Ladies and Gentlemen:

American Airlines, Inc., a Delaware corporation (the “Company”), proposes that Wilmington Trust Company, a Delaware trust company (“WTC”), acting not in its individual capacity but solely as pass through trustee (the “Trustee”) under the Pass Through Trust Agreement, dated September 16, 2014 (the “Basic Agreement”), as supplemented for the Company’s Pass Through Certificates, Series 2016-3B (the “Class B Certificates”) to be purchased hereunder by a Trust Supplement No. 2016-3B (the “Class B Trust Supplement”) between the Company and the Trustee (the Basic Agreement, as supplemented by the Class B Trust Supplement being referred to herein collectively as the “Class B Trust Agreement”), issue and sell to Credit Suisse Securities (USA) LLC (the “Underwriter” or “you”) the Class B Certificates, in the aggregate face amount and with the interest rate and final expected distribution date set forth on Schedule B hereto on the terms and conditions stated herein. The Company has previously offered $557,654,000 aggregate face amount of the Company’s Pass Through Certificates, Series 2016-3AA (the “Class AA Certificates”) that were issued pursuant to a Trust Supplement No. 2016-3AA and $256,143,000 aggregate face amount of the Company’s Pass Through Certificates, Series 2016-3A (the “Class A Certificates” and, together with the Class AA Certificates and the Class B Certificates, the “Certificates”) that were issued pursuant to Trust Supplement No. 2016-3A.

The Class B Certificates will represent interests in the Company’s 2016-3B Pass Through Trust (the “Class B Trust”), established pursuant to the Class B Trust Agreement to fund the purchase of equipment notes (the “Class B Equipment Notes”) to be issued by the Company in connection with the financing of (a) five Airbus A321-200S aircraft delivered new to American from November 2016 to February 2017, (b) eight Boeing 737-800 aircraft delivered new to American from March 2016 to December 2016, (c) four Boeing 787-9 aircraft delivered new to American from October 2016 to January 2017 and (d) eight Embraer ERJ 175 LR aircraft delivered new to American from September 2016 to December 2016 (each such aircraft, an “Aircraft” and collectively, the “Aircraft”). Subject to the terms and conditions of the Note Purchase Agreement (as defined below) and the relevant participation agreements between the Company and WTC, as Trustee, Loan Trustee and Subordination Agent, as amended and restated on the Closing Date (each, a “Participation Agreement”), the Class B Equipment Notes will be issued initially under 25 separate Indenture and Security Agreements between WTC, as Loan Trustee (the “Loan Trustee”), and the Company (each, including any supplements thereto and as amended and restated on the Closing Date, an “Indenture” and, collectively, the “Indentures”).

The cash proceeds from the sale of the Class B Certificates by the Class B Trust will be used by such Class B Trust to purchase Class B Equipment Notes in respect of the Aircraft at the Closing Time pursuant to a Note Purchase Agreement, to be amended and restated as of the Closing Date, among the Company, the Trustee and the Subordination Agent (as defined below) (the “Note Purchase Agreement”).

Certain amounts of interest payable on the Class B Certificates issued by the Class B Trust will be entitled to the benefits of a liquidity facility. KfW IPEX-Bank GmbH (the “Liquidity Provider”), and the Subordination Agent will enter into a revolving credit agreement with respect to the Class B Trust (the “Liquidity Facility”) to be dated as of the Closing Date, for the benefit of the holders of the Class B Certificates. The Liquidity Provider and the holders of the Class B Certificates will be entitled to the benefits of an Intercreditor Agreement, to be amended and restated as of the Closing Date (the “Intercreditor Agreement”), among the Trustee, the Liquidity Provider and WTC, as subordination agent and trustee thereunder (the “Subordination Agent”).

Capitalized terms not otherwise defined in this underwriting agreement (this “Agreement”) shall have the meanings specified therefor in the Class B Trust Agreement or the Intercreditor Agreement; provided that, as used in this Agreement, the term “Operative Documents” shall mean the Intercreditor Agreement, the Liquidity Facility, the Participation Agreements, the Indentures, the Class B Trust Agreement and the Note Purchase Agreement.

Any information included in such final prospectus that was omitted from the Original Registration Statement but that is deemed to be part of and included in such registration statement pursuant to Rule 430B(f) is referred to as the “Rule 430B Information.”

Each Operative Document to which the Company is, or is to be, a party, when duly executed and delivered by the Company, assuming that such document constitutes the legal, valid and binding obligation of each other party thereto, constitutes or will constitute, as the case may be, a valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except as may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting enforcement of creditors’ rights generally and by general principles of equity.

As used herein, “Repayment Event” means any event or condition which gives the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment prior to the stated maturity or date of mandatory redemption or repayment thereof of all or a portion of such indebtedness by the Company.

Other than as set forth in the General Disclosure Package and the Final Prospectus, there is no action, suit, proceeding, inquiry or investigation before or brought by any court or governmental agency or body, domestic or foreign, now pending, or, to the knowledge of the Company, threatened, against the Company or any of its subsidiaries which, in the judgment of the Company, is likely to result in a Material Adverse Effect.

In making the foregoing determination, the Class B Trust is relying upon the exemption from registration set forth in Rule 3a-7 under the 1940 Act, although additional exemptions or exclusions may be available to the Class B Trust.

(xix) Environmental Laws. There has been no storage, disposal, generation, manufacture, refinement, transportation, handling or treatment of toxic wastes, medical wastes, hazardous wastes or hazardous substances by the Company (or, to the knowledge of the Company, any of its predecessors in interest), or at, upon or from any of the property now or previously owned or leased by the Company in violation of, and the Company has no liability under, any applicable law, ordinance, rule, regulation, order, judgment, decree or permit or which would require remedial action under any applicable law, ordinance, rule,

regulation, order, judgment, decree or permit applicable to the Company, except for any violation, liability or remedial action which would not have, or could not be reasonably likely to have, singularly or in the aggregate with all such violations, liabilities and remedial actions, a Material Adverse Effect; there has been no spill, discharge, leak, emission, injection, escape, dumping or release of any kind by the Company onto such property or into the environment surrounding such property of any toxic wastes, medical wastes, solid wastes, hazardous wastes or hazardous substances due to or caused by the Company or with respect to which the Company has knowledge, except for any such spill, discharge, leak, emission, injection, escape, dumping or release which would not have or would not be reasonably likely to have, singularly or in the aggregate with all such spills, discharges, leaks, emissions, injections, escapes, dumpings and releases, a Material Adverse Effect. The terms “hazardous wastes,” “toxic wastes,” “hazardous substances” and “medical wastes” shall have the meanings specified in any applicable local, state, federal and foreign laws or regulations with respect to environmental protection or human health. In the ordinary course of its business, the Company conducts a periodic review of the effect of any and all applicable foreign, federal, state and local laws and regulations relating to the protection of human health and safety, the environment, and hazardous and toxic substances and wastes, pollutants and contaminants (“Environmental Laws”) on the business, operations and properties of the Company, in the course of which it identifies and evaluates associated costs and liabilities (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties). On the basis of such review, the Company has reasonably concluded that such associated costs and liabilities have not had and would not, singularly or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(xx) Insurance. The Company carries, or is covered by, insurance in such amounts and covering such risks as is adequate for the conduct of its business and the value of its properties.

3. Covenants. The Company covenants with the Underwriter as follows:

(a) Immediately following the execution of this Agreement, the Company will (x) prepare the Final Prospectus that complies with the Securities Act and the Securities Act Regulations and which sets forth the face amount of the Class B Certificates and their terms not otherwise specified in the basic prospectus relating to all offerings of pass through certificates under the Registration Statement and the face amount of the Class B Certificates that the Underwriter has agreed to purchase, the price at which the Class B Certificates are to be purchased by the Underwriter from the Trustee, any initial public offering price, any selling concession and reallowance, and such other information as you and the Company deem appropriate in connection with the offering of the Class B Certificates and (y) file all material required to be filed by the Company with the Commission pursuant to Rule 433(d) within the time required by such rule. The Company will promptly transmit copies of the Final Prospectus to the Commission for filing pursuant to Rule 424 and will furnish to the Underwriter as many copies of the Final Prospectus as you shall reasonably request.

(b) During the period when a prospectus (or in lieu thereof, a notice referred to in Rule 173(a) under the Securities Act (“Rule 173(a)”) relating to the Class B Certificates is required to be delivered under the Securities Act, the Company will promptly advise you of

(i) the effectiveness of any amendment to the Registration Statement, (ii) the transmittal to the Commission for filing of any supplement to the Final Prospectus or any document that would as a result thereof be incorporated by reference in the Final Prospectus, (iii) any request by the Commission for any amendment of the Registration Statement or any amendment or supplement to the Final Prospectus or for any additional information relating thereto or to any document incorporated by reference therein, (iv) the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the institution or threatening of any proceeding for that purpose, and (v) the receipt by the Company of any notification with respect to the suspension of the qualification of the Class B Certificates for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Company will use its best efforts to prevent the issuance of any such stop order or suspension and, if issued, to obtain as soon as possible the withdrawal thereof.

(c) If, at any time when a prospectus (or in lieu thereof, a notice referred to in Rule 173(a)) relating to the Class B Certificates is required to be delivered under the Securities Act, any event occurs as a result of which the Final Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or if it shall be necessary to amend or supplement the Final Prospectus to comply with the Securities Act or the Securities Act Regulations, the Company will promptly prepare and file with the Commission, subject to paragraph (d) of this Section 3, an amendment or supplement which will correct such statement or omission or an amendment or supplement which will effect such compliance and the Company will use its reasonable efforts to have any such amendment to the Registration Statement or new registration statement declared effective as soon as practicable (if it is not an automatic shelf registration statement with respect to the Class B Certificates). Neither the Underwriter’s consent to, nor the Underwriter’s delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 4 hereof.

(d) At any time when a prospectus (or in lieu thereof, a notice referred to in Rule 173(a)) relating to the Class B Certificates is required to be delivered under the Securities Act or the Securities Act Regulations, the Company will give you notice of its intention to file any amendment to the Registration Statement or any amendment or supplement to the Final Prospectus, whether pursuant to the Exchange Act, the Securities Act or otherwise, will furnish you with copies of any such amendment or supplement or other documents proposed to be filed within a reasonable time in advance of filing, and will not file any such amendment or supplement or other documents in a form to which you shall reasonably object.

(e) The Company has furnished or will furnish, if requested, to the Underwriter and its counsel, without charge, conformed copies of the Original Registration Statement and of all amendments thereto, whether filed before or after such Registration Statement originally became effective (including exhibits thereto and the documents incorporated therein by reference) and the copies of the Original Registration Statement and each amendment thereto furnished to the Underwriter will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T. So long as delivery of a Final Prospectus (or in lieu thereof, a notice referred to in Rule 173(a)) by the Underwriter may be required by the Securities Act, the Company will furnish as many copies of

any Statutory Prospectus, the Final Prospectus and any amendments thereof and supplements thereto as the Underwriter may reasonably request and the Final Prospectus and any amendments or supplements thereto furnished to the Underwriter will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T or required under Rule 424(e).

(f) The Company shall use its reasonable efforts, in cooperation with the Underwriter, to qualify the Class B Certificates for offering and sale under the applicable securities laws of such states in the United States as the Underwriter may reasonably designate and will maintain such qualifications in effect so long as required in connection with the distribution of the Class B Certificates; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any such jurisdiction in which it is not otherwise so subject.

(g) The Company shall use the proceeds received by it from the sale of the Class B Equipment Notes in the manner to be indicated in the Final Prospectus under “Use of Proceeds.”

(h) The Company shall cooperate with the Underwriter and use its reasonable efforts to permit the Class B Certificates to be eligible for clearance and settlement through the facilities of DTC.

(i) The Company, during the period when a Final Prospectus (or in lieu thereof, the notice referred to in Rule 173(a)) relating to the Class B Certificates is required to be delivered, will file promptly all documents required to be filed with the Commission pursuant to the Exchange Act within the time periods required by the Exchange Act and the Exchange Act Regulations.

(j) The Company represents and agrees that, unless it obtains the prior consent of the Underwriter, and the Underwriter represents and agrees that, unless it obtains the prior consent of the Company, it has not made and will not make any offer relating to the Class B Certificates that would constitute an “issuer free writing prospectus,” as defined in Rule 433 or that would otherwise constitute a “free writing prospectus” as defined in Rule 405. Any such free writing prospectus consented to by the Company and the Underwriter is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents that it has treated or agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rule 433 as applicable to any Permitted Free Writing Prospectus, including timely filing with the Commission where required, legending and record keeping.

(k) Between the date of this Agreement and the Closing Time, the Company will not, without the Underwriter’s prior consent, offer, sell or enter into any agreement to sell any public debt securities registered under the Securities Act (other than the Certificates) or any debt securities which may be sold in a transaction exempt from the registration requirements of the Securities Act in reliance on Rule 144A under the Securities Act and which are marketed through the use of a disclosure document containing substantially the same information as a prospectus for similar debt securities registered under the Securities Act.

(l) If by the third anniversary (the “Renewal Deadline”) of the initial effective date of the Original Registration Statement, any of the Class B Certificates remain unsold by the Underwriter, the Company will use its best efforts to file, if it has not already done so and is eligible to do so, a new automatic shelf registration statement relating to the Class B Certificates, in a form satisfactory to the Underwriter. If at the Renewal Deadline the Company is no longer eligible to file an automatic shelf registration statement, the Company will, if it has not already done so, use its best efforts to file a new shelf registration statement relating to the Class B Certificates, in a form satisfactory to the Underwriter and will use its best efforts to cause such registration statement to be declared effective within 180 days after the Renewal Deadline. The Company will take all other action necessary or appropriate to permit the public offering and sale of the Class B Certificates to continue as contemplated in the expired registration statement relating to the Class B Certificates. References herein to the Registration Statement shall include such new automatic shelf registration statement or such new shelf registration statement, as the case may be.

The Underwriter agrees that in the aggregate, the Class B Certificates will be widely offered. The Underwriter agrees that the Class B Certificates offered by it will be primarily offered in the United States to United States persons. The term “United States person” shall have the meaning set forth in section 7701(a)(30) of the Internal Revenue Code of 1986, as amended.

4. Conditions to the Obligations of the Underwriter. The obligations of the Underwriter to purchase and pay for the Class B Certificates pursuant to this Agreement shall be subject to the accuracy of and compliance with the representations and warranties of the Company contained herein as of the date hereof and as of the Closing Time, to the accuracy of the statements of the Company’s officers made in any certificates furnished pursuant to the provisions hereof, to the performance by the Company of its covenants and other obligations hereunder and to the following additional conditions:

Form T-1, and (ii) the Company shall not be liable for any loss, liability or expense of any settlement or compromise of or consent to entry of judgment with respect to, any pending or threatened litigation or any pending or threatened governmental agency investigation or proceeding if such settlement or compromise of or consent to entry of judgment with respect thereto is effected without the prior written consent of the Company (which consent shall not be unreasonably withheld), except to the extent that such consent is not required pursuant to Section 6(d) hereof. This indemnity agreement will be in addition to any liability that the Company may otherwise have.

(b) The Underwriter agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signed the Registration Statement, and each person who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, against any and all losses, claims, damages, liabilities and expenses described in the indemnity contained in Section 6(a) hereof, but only with respect to untrue statements or alleged untrue statements or omissions or alleged omissions made in the Registration Statement (or any amendment thereto), any Permitted Free Writing Prospectus, the General Disclosure Package, or the Final Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information relating to the Underwriter furnished to the Company by or on behalf of the Underwriter specifically for use in the Registration Statement (or any amendment thereto), the General Disclosure Package, any Permitted Free Writing Prospectus or the Final Prospectus (or any amendment or supplement thereto), it being understood and agreed that the only such information provided by the Underwriter consists of the information separately in writing identified to the Company; provided, however, that the Underwriter shall not be liable for any loss, liability or expense of any settlement or compromise of or consent to entry of judgment with respect to, any pending or threatened litigation or any pending or threatened governmental agency investigation or proceeding if such settlement or compromise of or consent to entry of judgment with respect thereto is effected without the prior written consent of the Underwriter (which consent shall not be unreasonably withheld), except to the extent that such consent is not required pursuant to Section 6(d) hereof. This indemnity agreement will be in addition to any liability that the Underwriter may otherwise have.

(c) Promptly after receipt by an indemnified party under Section 6(a) or (b) hereof of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under Section 6(a) or (b) hereof, notify the indemnifying party or parties in writing of the commencement thereof; but the omission so to notify the indemnifying party or parties will not relieve it from any liability which it may have to any indemnified party otherwise than under Section 6(a) or (b) hereof. In case any such action is brought against any indemnified party and it notifies the indemnifying party or parties of the commencement thereof, the indemnifying party or parties will be entitled to participate therein, and to the extent that such indemnifying party or parties may elect, by written notice delivered to such indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof, with counsel satisfactory to such indemnified party; provided, however, that if, in the reasonable judgment of such indemnified party, a conflict of interest exists where it is advisable for such indemnified party to be represented by separate counsel, the indemnified party shall have the right to employ separate counsel in any such action, in which event the fees and expenses of such separate counsel shall be borne by the indemnifying party or parties. Upon receipt of notice from the indemnifying party or parties to such

indemnified party of the election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party or parties will not be liable to such indemnified party under this Section 6 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party or parties shall not be liable for the expenses of more than one such separate counsel representing the indemnified parties under subparagraph (a) or (b), as applicable) of this Section 6 who are parties to such action in addition to one local counsel in each jurisdiction), (ii) the indemnifying party or parties shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action or (iii) the indemnifying party or parties have authorized the employment of counsel for the indemnified party at the expense of the indemnifying party or parties; and except that, if clause (i) or (iii) is applicable, such liability shall be only in respect of the counsel referred to in such clause (i) or (iii). It is understood that all such fees and expenses of counsel for the indemnified party for which the indemnifying party is liable shall be reimbursed as they are incurred. No indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld), effect any settlement or compromise of, or consent to entry of judgment with respect to, any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement or compromise of, or consent to entry of judgment with respect to, includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

(d) If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel payable pursuant to this Section 6, such indemnifying party agrees that it shall be liable for any settlement, compromise or consent to entry of judgment of the nature contemplated by clause (ii) of the proviso in Section 6(a) hereof and the proviso in Section 6(b) hereof effected without its written consent if (i) such settlement, compromise or consent to entry of judgment is entered into more than 45 days after receipt by such indemnifying party of the aforesaid notice of request, (ii) such indemnifying party shall have received notice of the terms of such settlement, compromise or consent to entry of judgment at least 30 days prior to such settlement being entered into, and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement, compromise or consent to entry of judgment.

(e) If the indemnification provided for in paragraph (a) or (b) of this Section 6 is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriter on the other hand from the offering of the Class B Certificates pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of

the Company on the one hand and of the Underwriter on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriter on the other hand in connection with the offering of the Class B Certificates pursuant to this Agreement shall be deemed to be in the same proportion as the total proceeds from the offering of the Class B Certificates pursuant to this Agreement (net of underwriting discounts and commissions paid to the Underwriter but before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriter in each case as set forth on the cover of the Final Prospectus, bears to the aggregate initial public offering price of the Class B Certificates as set forth on such cover. The relative fault of the Company on the one hand and the Underwriter on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriter agree that it would not be just and equitable if contribution pursuant to this Section 6 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 6. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 6 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any such action or claim. Notwithstanding the provisions of this Section 6, the Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the Class B Certificates underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which the Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 6, each person, if any, who controls the Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company.

7. Representations, Warranties, Covenants, Indemnities and Agreements to Survive Delivery. All representations, warranties, covenants, indemnities and agreements contained in this Agreement, or contained in certificates of officers of the Company submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of the Company or the Underwriter, its affiliates, their respective directors and officers or any controlling person of either and shall survive delivery of any Class B Certificates to the Underwriter.

8. Termination. This Agreement may be terminated immediately upon notice from you to the Company at any time at or prior to the Closing Time (i) if there has been, since the respective dates as of which information is given in the Registration Statement and the Final Prospectus (exclusive of any amendments or supplements thereto subsequent to the date of this Agreement), any material adverse change in the condition, financial or otherwise, of the Company and its subsidiaries considered as one enterprise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has occurred any outbreak or escalation of hostilities or any material adverse change in the financial markets in the United States or in the international financial markets or any other calamity or crisis the effect of any of which on the financial markets is such as to make it, in your judgment, impracticable to market the Class B Certificates or enforce contracts for the sale of the Class B Certificates, or (iii) if trading in the securities of AAG or the Company has been suspended by the Commission or the New York Stock Exchange, or if trading generally on the New York Stock Exchange has been suspended, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices for securities have been required, by said exchange or by order of the Commission or any other governmental authority, or (iv) if a banking moratorium has been declared by either Federal or New York authorities. In the event of any such termination, the provisions of Sections 5, 6 and 7 hereof shall remain in effect.

9. Notices. All notices and other communications hereunder shall be in writing and effective only upon receipt, and, if sent to the Underwriter, will be mailed or transmitted by any standard form of telecommunication to Credit Suisse Securities (USA) LLC, Eleven ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention: LCD-IBD or, if sent to the Company, will be mailed or transmitted by any standard form of telecommunication to the Company at ▇.▇. ▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇/▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇-▇▇▇▇, facsimile no.

Additionally, the Underwriter is not advising the Company or any of its subsidiaries as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction with respect to the offering of the Class B Certificates or the process leading thereto (irrespective of whether the Underwriter has advised or is advising AAG or the Company on other matters). The Underwriter advises that it and its affiliates are engaged in a

broad range of securities and financial services and that it and its affiliates may enter into contractual relationships with purchasers or potential purchasers of the securities of the Company or its affiliates and that some of these services or relationships may involve interests that differ from those of the Company and need not be disclosed to the Company, unless otherwise required by law. The Company has consulted with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriter shall not have any responsibility or liability to the Company or any of its subsidiaries or affiliates with respect thereto. Any review by the Underwriter of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriter and shall not be on behalf of the Company. The Company waives, to the fullest extent permitted by law, any claims it may have against the Underwriter for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Underwriter shall not have any liability (whether direct or indirect) to the Company in respect of such a fiduciary duty claim.

12. GOVERNING LAW. THIS AGREEMENT AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THIS AGREEMENT SHALL BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

13. Submission to Jurisdiction; Venue; Waiver of Jury Trial.

(a) The Company agrees that any suit or proceeding arising in respect of this Agreement or the Underwriter’s engagement will be tried exclusively in the U.S. District Court for the Southern District of New York or, if that court does not have subject matter jurisdiction, in any state court located in The City and County of New York and the Company agrees to submit to the jurisdiction of, and to venue in, such courts. Each of the parties to this Agreement agrees that a final action in any such suit or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other lawful manner.

(b) Each party hereto hereby irrevocably waives, to the fullest extent permitted by applicable law, and agrees not to assert, by stay of motion, as a defense, or otherwise, in any legal action or proceeding brought hereunder in any of the above-named courts, that such action or proceeding is brought in an inconvenient forum, or that venue for the action or proceeding is improper.

(c) Each party hereto hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

14. Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriter is required to obtain, verify and record information that identifies its clients, including the Company, which information may include the name and address of their its clients, as well as other information that will allow the Underwriter to properly identify its clients.

15. Effect of Headings. The Section headings herein are for convenience only and shall not affect the construction hereof.

16. Counterparts. This Agreement may be executed in one or more counterparts and when a counterpart has been executed by each party hereto all such counterparts taken together shall constitute one and the same agreement.

Re: American Airlines, Inc. Pass Through Certificates, Series 2016-3B

Ladies and Gentlemen:

We have acted as counsel to (i) Wilmington Trust Company, a Delaware trust company (in its individual capacity, “WTC”; in its capacity as Subordination Agent, Paying Agent, Pass Through Trustee or Loan Trustee, the “Trustee”), and (ii) Wilmington Trust, National Association (in its individual capacity, “WTNA”; in its capacity as Escrow Agent, the “Escrow Agent”), a national banking association, in connection with the transactions contemplated by a Pass Through Trust Agreement, dated as of September 16, 2014, between WTC, as Pass Through Trustee, and American Airlines, Inc. (“American”) (the “Basic Agreement”), as supplemented by one Pass Through Trust Supplement, dated as of the date hereof (a “Trust Supplement” and, together with the Basic Agreement, as so supplemented, the “Pass Through Trust Agreement”). This opinion is furnished pursuant to Section [ ] of the Class B Underwriting Agreement, dated [ ], 2017 (the “Underwriting Agreement”), between American and Credit Suisse Securities (USA) LLC, as the Underwriter. Capitalized terms used herein and not otherwise defined are used as defined in the Underwriting Agreement, except that reference herein to any document shall mean such document as in effect as of the date hereof.

We have examined executed counterparts of the following documents:

(h)

the Underwriting Agreement;

(i)

(1) the Registration Statement on Form S-3 (Registration No. 333-216167-01), filed by American under the Securities Act of 1933, as amended, and the rules and regulations thereunder (the “Securities Act”), with the Securities and Exchange Commission on February 22, 2017, including the exhibits thereto and the documents filed by American with the Securities and Exchange Commission pursuant to the Securities Exchange Act of 1934, as amended, that are incorporated by reference therein and also including the information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430B under the Securities Act, (2) the base prospectus dated February 22, 2017 related to pass through certificates included in the Registration Statement, (3) the preliminary prospectus supplement of American dated September 20, 2017, relating to the Pass Through Certificates, Series 2016-3B (the “Certificates”) in the form filed pursuant to Rule 424(b) under the Securities Act, including the documents incorporated by reference therein, (4) the free writing prospectuses identified in Section A to the Underwriting Agreement, and (5) the final prospectus supplement of American dated [ ], 2017, relating to the Certificates in the form filed pursuant to Rule 424(b) under the Securities Act, including the documents incorporated by reference therein (collectively, the “Prospectus”); and

(j)

the Certificates (with attached Escrow Receipts) being issued today in definitive form.

We have also examined originals or copies of such other documents and such corporate records, certificates and other statements of governmental officials and corporate officers and other representatives of the corporations or entities referred to herein as we have deemed necessary or appropriate for the purposes of this opinion. Moreover, as to certain facts material to the opinions expressed herein, we have relied upon the representations and warranties contained in the documents referred to in this paragraph.

Based upon the foregoing and upon an examination of such questions of law as we have considered necessary or appropriate, and subject to the assumptions, exceptions and qualifications set forth below, we advise you that, in our opinion:

1. WTC is a trust company duly organized and validly existing in good standing under the laws of the State of Delaware, and has the corporate power and authority to execute, deliver and perform its obligations under, in its individual capacity, or as Trustee, as the case may be, the Transaction Documents and the Certificates. WTC is a “citizen of the United States” as defined in 49 U.S.C. § 40102.

2. Each of the Transaction Documents has been duly authorized, executed and delivered by WTC in its individual capacity, or as Trustee, as the case may be, and constitutes the legal, valid and binding obligation of WTC in its individual capacity, or as Trustee, as the case may be, enforceable against WTC in its individual capacity, or as Trustee, as the case may be, in accordance with its terms. The Pass Through Trust Agreement is a legal, valid and binding obligation of American, enforceable against American in accordance with its terms.

3. WTC, solely in its capacity as Trustee, has duly authorized, issued, executed and delivered the Certificates to the holders thereof pursuant to the terms and provisions of the Pass Through Trust Agreement; the Certificates are duly authorized, legal, valid and binding obligations of the Class B Trust (as defined in the Intercreditor Agreement), enforceable against the Class B Trust in accordance with their terms and the terms of the Pass Through Trust Agreement and are entitled to the benefits of the Pass Through Trust Agreement.

4. No authorization, consent or approval of, notice to or filing with, or the taking of any other action in respect of, any governmental authority or agency of the United States or the State of Delaware governing the trust powers of WTC is required for the execution, delivery or performance by WTC in its individual capacity, or as Trustee, as the case may be, of the Transaction Documents or the Certificates.

5. Neither the execution, delivery or performance by WTC in its individual capacity, or as Trustee, as the case may be, of the Transaction Documents or the Certificates, nor compliance with the terms and provisions thereof, conflicts with the charter or bylaws of WTC or results in a breach or violation of any of the terms, conditions or provisions of any law, governmental rule or regulation of the United States or the State of Delaware governing the trust powers of WTC or, to our knowledge, any order, writ, injunction or decree of any court or governmental authority against WTC or by which it or any of its properties is bound or, to our knowledge, any indenture, mortgage, contract or other agreement or instrument to which WTC is a party or by which it or any of its properties is bound, or constitutes a default thereunder.

6. Assuming that the Class B Trust will not be taxable as corporations, but, rather, will be classified as grantor trusts under subpart E, Part I of Subchapter J of the United States Internal Revenue Code of 1986, as amended (the “Code”), or as a partnership under Subchapter K of the Code, (i) the Class B Trust will not be subject to any tax (including, without limitation, net or gross income, tangible or intangible property, net worth, capital, franchise or doing business tax), fee or other governmental charge under the laws of the State of Delaware or any political subdivision thereof and (ii) the Certificateholders (as defined in the Basic

Agreement) that are not residents of or otherwise subject to tax in Delaware will not be subject to any tax (including, without limitation, net or gross income, tangible or intangible property, net worth, capital, franchise or doing business tax), fee or other governmental charge under the laws of the State of Delaware or any political subdivision thereof as a result of purchasing, holding (including receiving payments with respect to) or selling a Certificate.

7. The statements set forth under the caption “Certain Delaware Taxes” in the Prospectus, insofar as such statements purport to constitute summaries of Delaware tax law and regulations or legal conclusions with respect thereto, are accurate summaries of the matters described therein in all material respects.

8. To our knowledge, there are no proceedings pending or threatened against or affecting WTC in any court or before any governmental authority, agency, arbitration board or tribunal which, if adversely determined, individually or in the aggregate, would materially and adversely affect the Class B Trust or question the right, power and authority of WTC in its individual capacity, or as Trustee, as the case may be, to enter into or perform its obligations under the Transaction Documents or which would call into question or challenge the validity of any of the Transaction Documents or the enforceability thereof.

9. The Series B Equipment Notes (as defined in the Note Purchase Agreement) to be delivered to and registered in the name of the Subordination Agent pursuant to the Participation Agreements, the Indentures (each as defined in the Intercreditor Agreement), the Note Purchase Agreement and the Intercreditor Agreement will be held by the Subordination Agent in trust as trustee for the Class B Trustee under the Pass Through Trust Agreement on behalf of the Certificateholders of the Class B Trust.

10. WTNA is a national banking association duly organized and validly existing in good standing under the laws of the United States of America and has the corporate power and authority to execute, deliver and perform its obligations under, in its individual capacity, or as Escrow Agent, as the case may be, the Transaction Documents.

11. Each of the Transaction Documents has been duly authorized, executed and delivered by WTNA in its individual capacity, or as Escrow Agent, as the case may be, and constitutes a legal, valid and binding obligation of WTNA in its individual capacity, or as Escrow Agent, as the case may be, enforceable against WTNA in its individual capacity, or as Escrow Agent, as the case may be, in accordance with its terms.

12. No authorization, consent or approval of, notice to or filing with, or the taking of any other action in respect of, any governmental authority or agency of the State of Delaware or the United States of America governing the banking and trust powers of WTNA is required for the execution, delivery or performance by WTNA in its individual capacity, or as Escrow Agent, as the case may be, of the Transaction Documents.

13. Neither the execution, delivery or performance by WTNA in its individual

capacity, or as Escrow Agent, as the case may be, of the Transaction Documents, nor compliance with the terms and provisions thereof, conflicts with the charter or bylaws of WTNA or results in a breach or violation of any of the terms, conditions or provisions of any law, governmental rule or regulation of the State of Delaware or the United States governing the banking and trust powers of WTNA or, to our knowledge, any order, writ, injunction or decree of any court or governmental authority against WTNA or by which it or any of its properties is bound or, to our knowledge, any indenture, mortgage, contract or other agreement or instrument to which WTNA is a party or by which it or any of its properties is bound, or constitutes a default thereunder.

The foregoing opinions are subject to the following assumptions, exceptions and qualifications:

A. We are admitted to practice law in the State of Delaware and do not hold ourselves out as being experts on the law of any other jurisdiction. The foregoing opinions are limited to the laws of the State of Delaware, the federal laws of the United States of America governing the trust powers of WTC and the federal laws of the United States of America governing the banking and trust powers of WTNA, except that we express no opinion with respect to (i) federal securities laws, including the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, the Investment Company Act of 1940, as amended, and the Trust Indenture Act of 1939, as amended, (ii) Part A of Subtitle VII of Title 49 of the United States Code, as amended (except with respect to the opinion set forth in paragraph 1 above concerning the citizenship of WTC), (iii) the Federal Communications Act of 1934, as amended, (iv) state securities or blue sky laws, or (v) laws, rules and regulations applicable to the particular nature of the equipment acquired by American. Insofar as the foregoing opinions relate to the validity and enforceability of the Transaction Documents expressed to be governed by the laws of the State of New York, we have assumed that each such document is legal, valid, binding and enforceable in accordance with its terms under such laws (as to which we express no opinion).

B. The foregoing opinions regarding enforceability are subject to (i) applicable bankruptcy, insolvency, moratorium, receivership, reorganization, fraudulent conveyance and similar laws relating to or affecting the rights and remedies of creditors generally, and (ii) principles of equity (regardless of whether considered and applied in a proceeding in equity or at law).

C. We have assumed the due authorization, execution and delivery by each of the parties thereto (other than WTC in its individual capacity, or as Trustee, as the case may be, or WTNA in its individual capacity, or as Escrow Agent, as the case may be) of the Transaction Documents, and that each of such parties has the full power, authority and legal right to execute, deliver and perform each such document.

D. We have assumed that all signatures (other than those of WTC in its individual capacity, or as Trustee, as the case may be, or WTNA in its individual capacity, or as Escrow Agent, as the case may be) on documents examined by us are genuine, that all documents submitted to us as originals are authentic, and that all documents submitted to us as copies or specimens conform with the originals, which facts we have not independently verified.

E. The opinions expressed in paragraph 8 above regarding any pending litigation or court order with respect to the Trusts are limited solely to our search as of the date hereof of public records of the Chancery Court of the State of Delaware in and for New Castle County, the Superior Court of the State of Delaware in and for New Castle County and the United States District Court for the District of Delaware.

F. We have not participated in the preparation of any offering materials with respect to the Certificates and assume no responsibility for their contents.

G. In basing the opinions set forth herein on “our knowledge,” the words “our knowledge” signify that no information has come to the attention of the attorneys in the firm who are directly involved in the representation of WTC or WTNA in this transaction that would give us actual knowledge that any such opinions are not accurate. Except as otherwise stated herein, we have undertaken no independent investigation or verification of such matters.

This opinion may be relied upon by you in connection with the matters set forth herein. We also consent to the reliance upon this opinion as to matters of Delaware law by ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP and Milbank, Tweed, ▇▇▇▇▇▇ & ▇▇▇▇▇▇ LLP as if it were addressed to them, in rendering their opinions to you of even date herewith. Except as stated above, without our prior written consent, this opinion may not be furnished or quoted to, or relied upon by, any other person or entity for any purpose.

Very truly yours,

MML/mag

Re:

Ladies and Gentlemen:

We have acted as special New York (the “State”) counsel to KfW IPEX-Bank GmbH (“KfW IPEX-Bank”), in connection with the negotiation, execution and delivery of (i) the Revolving Credit Agreement (2016-3B) dated as of [ ], 2017 (the “Class B Liquidity Facility”) by and between KfW IPEX-Bank, as Liquidity Provider, and Wilmington Trust Company, not in its individual capacity but solely as Subordination Agent and as agent and trustee for the trustee of the American Airlines Pass Through Trust 2016-3B (the “Class B Trust”), as Borrower under the Class B Liquidity Facility and (ii) the Amended and Restated Intercreditor Agreement (2016-3) dated as of [ ], 2017 (the “Intercreditor Agreement”, and together with the Class B Liquidity Facility, the “Opinion Documents”) among Wilmington Trust Company, not in its individual capacity but solely as Trustee of the Class AA Trust, the Class A Trust and the Class B Trust, KfW IPEX-Bank, as the Class AA Liquidity Provider, the Class A Liquidity Provider and the Class B Liquidity Provider, and Wilmington Trust Company, as Subordination Agent. This opinion is delivered to you at the request of our client pursuant to Section 4(b)(3) of the Underwriting Agreement with respect to the purchase of the Class B Certificates.

Except as otherwise noted herein, all capitalized terms used herein shall have the respective defined meanings set forth in the Intercreditor Agreement, or by reference therein. In our capacity as special counsel to KfW IPEX-Bank, we have examined each of the Opinion Documents.

On the basis of the assumptions and subject to the qualifications and limitations set forth below, we are of the opinion that:

1. The Opinion Documents constitute the valid and legally binding agreements of KfW IPEX-Bank, enforceable against KfW IPEX-Bank in accordance with their respective terms.

2. The execution, delivery and performance by KfW IPEX-Bank of the Opinion Documents and the consummation of the transactions contemplated therein do not and will not violate any banking law, or any governmental rule or regulation relating thereto, of the United States of America or the State.

3. No authorization, consent, approval or other action by, and no notice to or filing with, any banking authority or regulatory body of the United States of America or the State is required for the due execution, delivery and performance by KfW IPEX-Bank of the Opinion Documents, as the case may be, other than administrative and ministerial filings which KfW IPEX-Bank is obligated to make in the ordinary course of its business (which filings we have assumed have been and will continue to be made in a timely manner).

Our opinions are subject to the following qualifications and limitations:

(b) We express no opinion with respect to the enforceability of (A) any consent to jurisdiction clause or waiver of inconvenient forum clause, insofar as any such clause relates to federal courts (except as to the personal jurisdiction thereof); (B) any waiver of trial by jury clause insofar as such clause is sought to be enforced in a federal court, (C) any forum-selection clause, or (D) any choice of venue clause, i.e., requiring actions to be commenced in a particular court in a particular jurisdiction.

(c) In giving our opinions 2 and 3, we have, without independent investigation or verification, relied in part on the opinion dated the date hereof and addressed to you by an in-house counsel of KfW IPEX-Bank, attached hereto as Exhibit B.

In rendering our opinions:

(i) We have, without independent verification, relied, with respect to factual matters, statements and conclusions, on certificates and statementsof governmental officials and of individuals identified to us as officials of KfW IPEX-Bank and on the representations and warranties made by KfW IPEX-Bank in the Opinion Documents.

(ii) We have examined originals, or copies of originals certified, conformed or otherwise identified to our satisfaction, of such agreements, documents and records as we have considered relevant and necessary as a basis for this opinion.

(iii) We have assumed the accuracy, completeness and authenticity of all original certificates, agreements, documents, records and other materials submitted to us, the conformity with the originals of any copies submitted to us, the genuineness of all signatures and the legal capacity of natural persons.

(iv) We have assumed that (A) KfW IPEX-Bank (1) is duly incorporated or organized, validly existing and in good standing under the laws of the Federal Republic of Germany and (2) has the corporate power and has taken all necessary action to authorize it to execute and deliver, and to perform its obligations under, and has duly executed and delivered, each of the Opinion Documents; (B) the execution, delivery and performance by KfW IPEX-Bank of the Opinion Documents do not and will not (1) violate or conflict with, result in a breach of, constitute a default under, (aa) the organizational documents of KfW IPEX-Bank, (bb) any agreement or instrument to which KfW IPEX-Bank or any of its affiliates is a party or by which KfW IPEX-Bank or any of its affiliates or any of their respective properties may be bound, (cc) any authorization, consent, approval (including without limitation all foreign exchange control approvals) or license (or the like) of, or exemption (or the like) from, any governmental unit, agency, commission, department or other authority granted to or otherwise applicable to KfW IPEX-Bank or any of its affiliates or any of their respective properties (each a “Governmental Approval”) (other than the Governmental Approvals that are the subject of our opinion in

paragraph 3 above), (dd) any registration or filing (or the like) with, or report or notice (or the like) to, any governmental unit, agency, commission, department or other authority, including without limitation the central bank of the Federal Republic of Germany, made by or otherwise applicable to KfW IPEX-Bank or any of its affiliates or any of their respective properties (each a “Governmental Registration”) (other than the Governmental Registrations that are the subject of our opinion in paragraph 3 above), (ee) any order, decision, judgment or decree that may be applicable to KfW IPEX-Bank or any of its affiliates or any of their respective properties or (ff) any law (other than the federal law of the United States of America and the law of the State, each as in effect on the date hereof), or (2) require any Governmental Approval or any Governmental Registration (other than the Governmental Approvals and Governmental Registrations that are the subject of our opinion in paragraph 3 above); (C) all parties to the transactions contemplated in the Opinion Documents will act in accordance with, and will refrain from taking any action that is forbidden by, the terms and conditions of the Opinion Documents; and (D) there are no agreements, instruments, understanding or negotiations between the parties not set forth in the Opinion Documents that would modify the terms or rights and obligations of the parties thereunder.

(v) We have assumed that the Opinion Documents constitute (subject to the same qualifications as are contained in subparagraph (A) of the immediately preceding paragraph above) the valid, legally binding and enforceable agreements of the parties thereto under all applicable law (other than, in the case of KfW IPEX-Bank, the federal law of the United States of America and the law of the State).

(vi) We have assumed that there exists no provision of any law (other than federal law of the United States of America and the law of the State) which would adversely affect the enforceability of the Opinion Documents.

(vii) We have assumed that the choice of law of the State as the governing law of the Opinion Documents would not result in a violation of an important public policy of another state or country having greater contacts with the transactions contemplated by the Opinion Documents other than the State.

We express no opinion as to the law of any jurisdiction other than the law of the State (excluding the securities and blue sky laws of such State, as to which we express no opinion) and the federal law of the United States of America (excluding the federal securities laws, customs laws and international trade laws as to which we express no opinion), in each case that a New York lawyer exercising customary professional diligence would reasonably be expected to recognize as being applicable to transactions

of the type reflected in the Opinion Documents and not including any law that is part of a regulatory regime applicable to specific assets or business of any party to any of the Opinion Documents (other than the laws that are the subject of our opinions in paragraphs 2 and 3) and not including charters, ordinances, bylaws and other laws enacted by political subdivisions of the State.

This opinion speaks only as of the date hereof. We have no responsibility or obligation to update this letter or to take into account changes in law, facts or any other developments of which we may later become aware.

This opinion is rendered by us as special counsel for KfW IPEX-Bank solely for your benefit in connection with the transaction referred to herein and may not be used, circulated, quoted or otherwise referred to or relied upon for any other purpose or by any other person without our prior written consent, except that this letter may be disclosed to (a) legal counsel of the persons listed on Exhibit A hereto and (b) others insofar as it relates to the income tax treatment or tax structure of the transaction.

[KfW IPEX-Bank LETTERHEAD]

, 2017

To: The Addressees listed on Exhibit A to this opinion letter

Re: Liquidity Facility relating to American Airlines Pass Through Trust 2016-3B

Ladies and Gentlemen:

As in-house counsel to KfW IPEX-Bank GmbH (“KfW IPEX-Bank”) I have been asked to give this legal opinion. In this connection, I have reviewed the following documents (collectively, the “Documents”):

(i)

a copy of the Revolving Credit Agreement (2016-3B) dated as of , 2017 (the “Class B Liquidity Facility”) between (a) Wilmington Trust Company, not in its individual capacity but solely as Subordination Agent and as agent and trustee for the trustee of the American Airlines Pass Through Trust 2016-3B (the “Class B Trust”), as borrower and (b) KfW IPEX-Bank, as “Class B Liquidity Provider”; and

(ii)

a copy of the Amended and Restated Intercreditor Agreement dated as of , 2017 (the “Intercreditor Agreement”) among (a) Wilmington Trust Company, not in its individual capacity but solely as trustee of the Class AA Trust, the Class A Trust and the Class B Trust, (b) KfW IPEX-Bank, as the Class AA Liquidity Provider, the Class A Liquidity Provider and the Class B Liquidity Provider, and (c) Wilmington Trust Company as Subordination Agent.

Unless otherwise defined in this opinion letter, terms used but not defined herein have the meanings ascribed thereto in the Intercreditor Agreement, or by reference therein.

I have also examined such other documents and corporate records of KfW IPEX-Bank and have made such investigations in respect of KfW IPEX-Bank as I have deemed necessary for the purpose of giving this opinion. This opinion is being furnished pursuant to Section 4(b)(4) of the Underwriting Agreement with respect to the purchase of the Class B Certificates.

In giving this opinion I have assumed that all documents submitted to me as copies or specimen documents are complete and conform to the originals of such documents, that all documents have, where applicable, been executed in the form examined by me and that the signatures on the originals of all documents submitted to me, other than the signatures of KfW IPEX-Bank’s officers, are genuine. In my examination I have assumed that all such documents are within the capacity and power of, have been duly executed and delivered and also duly authorized by or on behalf of each of the parties thereto other than KfW IPEX-Bank and that there has been no breach of the terms thereof. As to various questions of fact material to my opinion, I have relied upon information provided to us by officers of KfW IPEX-Bank. I have also assumed:

(a)

There is nothing in New York law or the law of any other jurisdiction (other than Germany) nor any other document (other than the Documents) which affects the matters addressed by this opinion.

(b)

Each party to the Documents (other than KfW IPEX-Bank) is duly incorporated and validly existing under the laws of the place of its incorporation.

(c)

Insofar as any obligation falls to be performed in any jurisdiction outside Germany, its performance will not be illegal or ineffective by virtue of the laws of that jurisdiction.

(d)

that the Documents constitute legal, valid, binding and enforceable obligations of KfW IPEX-Bank under the laws of the State of New York;

(e)

that the Documents constitute legal, valid and binding obligations of the parties to the Documents (other than KfW IPEX-Bank) under the laws of their place of incorporation or organization and all other applicable laws and have been and remain duly approved and authorized by all necessary corporate, governmental and other action in accordance with their constitutive documents, the laws of their place of incorporation or organization and such other laws; and

(f)

the correctness of the representations as to factual matters made in each of the Documents.

No opinion is expressed herein as to the laws of any jurisdiction other than the laws of the Federal Republic of Germany (“Germany”).

Based upon the foregoing and subject to the assumptions and reservations set forth herein and matters of fact, documents or events not disclosed to me, in connection with the obligations of KfW IPEX-Bank under the Documents, I am of the opinion that insofar as the laws of Germany are concerned:

1.	KfW IPEX-Bank is a private limited liability company (Gesellschaft mit beschränkter Haftung) incorporated under the laws of Germany with full legal capacity (“unbeschränkter Rechtsfähigkeit”), is duly established and validly exists as a credit institution under the laws of Germany.

2.	KfW IPEX-Bank has unlimited corporate existence and has the corporate power and authority to execute and deliver, and perform its obligations under, the Documents, and execution, delivery and performance under the Documents has been duly authorized by KfW IPEX-Bank;

KfW IPEX-Bank has the power to enter into the Documents which have been (i) duly executed on behalf of KfW IPEX-Bank when signed by any two of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ or ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇, as duly appointed officers of KfW IPEX-Bank, and (ii) duly delivered by KfW IPEX-Bank on the date hereof;

the obligations of KfW IPEX-Bank under the Documents are legal, valid, binding and enforceable against KfW IPEX-Bank under the laws of Germany (assuming the Documents are legal, valid, binding and enforceable under New York law), except to the extent that enforcement may be limited by equitable principles and applicable bankruptcy, insolvency, re-organization, moratorium or other similar laws and judicial decisions affecting creditors’ rights generally;

5.	it is not necessary that any of the Documents be filed, recorded or enrolled with any public office, governmental authority or court in Germany in order to ensure the legality or validity of the Documents in Germany;

to the best of my knowledge, there are no pending actions, suits or proceedings against KfW IPEX-Bank which if adversely determined (i) would materially and adversely affect the ability of KfW IPEX-Bank to perform its obligations under the Documents or (ii) would render the Documents invalid or unenforceable;

7.	no consent or approval of any governmental or public bodies or authorities or courts of Germany is required by KfW IPEX-Bank in connection with the execution and delivery of the Documents and the performance by KfW IPEX-Bank of its obligations under the Documents;

8.	the execution, delivery and performance of the Documents does not violate any law of Germany applicable to KfW IPEX-Bank and does not contravene any of KfW IPEX Bank’s organizational documents;

the choice of the law of the State of New York to govern the obligations of the parties under the Documents will be upheld as a valid choice of law in any action brought in connection with the Documents in the courts of Germany against KfW IPEX-Bank and the submission by KfW IPEX-Bank to the non-exclusive jurisdiction of the courts of the State of New York, the courts of the United States of America for the Southern District of New York, and the appellate courts from any thereof under such Documents is binding on KfW IPEX-Bank;

10.

any final and conclusive judgment rendered by the Supreme Court of the State of New York or by the United States District Court for the Southern District of New York for a definite sum for the recovery of amounts due and unpaid by KfW IPEX-Bank under the Documents will be enforceable against KfW IPEX-Bank in Germany without re-examination or re-litigation of the matters adjudicated subject to the applicable rules for obtaining a necessary executory decision (action upon the foreign judgment) issued by a competent German court. Such a decision will not be rendered if any of the reasons for excluding enforceability set out in Section 328 (1) of the German Code of Civil Procedure (Zivilprozessordnung—ZPO) is present, in particular, if:

(a)

under German law the said state or federal court did not have jurisdiction;

(b)

KfW IPEX-Bank has not been served with process in a proper and timely fashion and has not defended itself against the claim in court;

(c)

the judgment conflicts with a prior judgment relating to the same matter of a German court or a prior judgment relating to the same matter of a foreign court which is to be recognized in Germany, or the litigation resulting in the judgment to be enforced conflicts with litigation relating to the same matter previously commenced in Germany;

(d)

recognition of the judgment would clearly be contrary to basic principles of German law or public policy, in particular the constitutional human rights (“Grundrechte”), though we do not know of any such conflict; or

(e)

reciprocity is not ensured; I understand that reciprocity for the recognition of judgments currently exists between Germany and the State of New York, but I must point out that such reciprocity might cease to exist at any time.

11.

the payment obligations of KfW IPEX-Bank under the Class B Liquidity Facility rank pari passu with its obligations to pay any other unsecured and unprivileged obligations of KfW IPEX-Bank for borrowed money that are not preferred by contractual stipulations or by law or in proceedings under the Insolvency Code (Insolvenzordnung) or by similar laws affecting creditors’ rights generally.

12.	In any proceeding taken in Germany in relation to the Documents, KfW IPEX-Bank will not be entitled to claim for itself or any of its assets immunity from suit, execution, attachment or other legal process.

The opinions set forth above are subject to the following reservations:

(a)

the courts in Germany may not enforce any provision of the Documents or any obligation or right in connection therewith which is or becomes illegal under the law of the foreign jurisdiction in which it is to be performed or which may be contrary to public policy or mandatory provisions of German law;

(b)

enforcement of the obligations under the Documents in a German court may be affected by prescription or lapse of time, bankruptcy, insolvency, liquidation, re-organization, reconstruction or similar laws and judicial decisions affecting creditors’ rights generally;

(c)

provisions in any of the Documents providing that certain certifications or determinations will be conclusive and binding will not necessarily prevent judicial enquiry by a German court into the merits of any claim by an aggrieved party; and

(d)

as regards provisions in the Documents relating to jurisdiction, a German court may stay proceedings if concurrent proceedings are being brought elsewhere;

(e)

the relevant contents of New York law must be duly proved in any such action on proceeding and

(f)

the enforcement of a foreign judgment in Germany or the commencement of proceedings in Germany are subject to the German laws of civil procedure and enforcement, which inter alia without limitation will require the translation of foreign language documents into the German language by an official sworn translator and a German court might decide on the costs to be borne by the parties otherwise than as contemplated in any contract or judgment. Such rules shall not be discriminatory against foreign parties to such enforcement or other proceedings.

This opinion speaks only as of the date hereof and is solely for the benefit of the addressees of this opinion letter listed on Exhibit A, their successors and permitted assigns. This opinion is limited to matters of German law as in force at the date of this opinion. This opinion may not be delivered to or relied upon by any other person, firm, corporation or entity without my express prior consent in writing and is strictly limited to the matters stated herein and is not to be used or extended by implication to any other matter whether in connection with the Documents or any of them or otherwise; provided that a copy of this opinion may be furnished (but such recipients may not rely on this opinion) without my prior written consent to (i) any prospective successors or assigns; (ii) your legal and other advisors; (iii) any legislative, administrative, regulatory or judicial body having jurisdiction over you to the extent required by applicable law; and (iv) any person pursuant to legal process. I assume no obligation to advise any of the addressees of any change that may hereafter be brought to our attention.

This opinion is issued in Germany and the signing in-house counsel in its capacity as representative of KfW IPEX-Bank. Consequently, this opinion is exclusively issued by KfW IPEX-Bank and the undersigned is excluded from any personal liability in connection herewith.

Very truly yours,

KfW IPEX-Bank GmbH
