Section 1.03. Initial Escrow Amount; Issuance of Escrow Receipts. The Escrow Agent hereby directs the Underwriters to, and the Underwriters hereby acknowledge that on the date hereof they shall, irrevocably deliver to the Depositary on behalf of the Escrow Agent, an amount in U.S. dollars (“Dollars”) and immediately available funds equal to $235,765,000 for deposit on behalf of the Escrow Agent with the Depositary in accordance with Section 2.1 of the Deposit Agreement. The Underwriters hereby instruct the Escrow Agent, upon receipt by the Depositary of such sum from the Underwriters, to confirm such receipt by executing and delivering to the Pass Through Trustee an Escrow Receipt in the form of Exhibit A hereto (each, an “Escrow Receipt” and, collectively, the “Escrow Receipts”) (a) to be affixed by the Pass Through Trustee to each Certificate and (b) to evidence the same percentage interest (the “Escrow Interest”) in the Account Amounts (as defined below) as the Fractional Undivided Interest in the Pass Through Trust evidenced by the Certificate to which such Escrow Receipt is to be affixed. The Escrow Agent shall provide to the Pass Through Trustee for attachment to each Certificate newly issued under and in accordance with the Pass Through Trust Agreement an executed Escrow Receipt as the Pass Through Trustee may from time to time request of the Escrow Agent. Each Escrow Receipt shall be registered by the Escrow Agent in a register (the “Register”) maintained by the Escrow Agent in the name of the same holder that is the holder of the Certificate to which such Escrow Receipt is attached and may not thereafter be detached from such Certificate to which it is to be affixed. No Escrow Receipt may be assigned or transferred except in connection with the assignment or transfer of the Certificate to which such Escrow Receipt is affixed. After the termination of the Deposit Agreement (or, if applicable, any Replacement Deposit Agreement), no additional Escrow Receipts shall be issued and the Pass Through Trustee shall request the return to the Escrow Agent for cancellation of all outstanding Escrow Receipts.

Section 1.04. Payments to Receiptholders. All payments and distributions made to a holder (each, a “Receiptholder” and, collectively, the “Receiptholders”) of an Escrow Receipt in respect of such Escrow Receipt shall be made only from amounts deposited in the Paying Agent Account (as defined below) (the “Account Amounts”). Each Receiptholder, by its acceptance of an Escrow Receipt, agrees that (a) it will look solely to the Account Amounts for any payment or distribution due to such Receiptholder pursuant to the terms of such Escrow Receipt and this Agreement (subject to Section 16 hereof) and (b) it will have no recourse to American, the Pass Through Trustee, the Paying Agent or the Escrow Agent, except as expressly provided herein or in the Pass Through Trust Agreement. No Receiptholder shall have any right to vote or in any manner otherwise control the operation and management of the Paying Agent Account (as defined below) or the obligations of the parties hereto, nor shall anything set forth herein, or contained in the terms of any Escrow Receipt, be construed so as to constitute the Receiptholders from time to time as partners or members of an association.

Section 1.05. Mutilated, Destroyed, Lost or Stolen Escrow Receipt. If (a) any mutilated Escrow Receipt is surrendered to the Escrow Agent or the Escrow Agent receives evidence to its satisfaction of the destruction, loss or theft of any Escrow Receipt and (b) there is delivered to the Escrow Agent and the Pass Through Trustee such security, indemnity or bond, as may be required

Escrow and Paying Agent Agreement (Class B)

(American Airlines 2026-1 EETC)

by them to hold each of them harmless, then, absent notice to the Escrow Agent or the Pass Through Trustee that such destroyed, lost or stolen Escrow Receipt has been acquired by a bona fide purchaser, and provided that the requirements of Section 8-405 of the Uniform Commercial Code in effect in any applicable jurisdiction are met, the Escrow Agent shall execute and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Escrow Receipt, a new Escrow Receipt or Escrow Receipts of like Escrow Interest in the Account Amounts and bearing a number not contemporaneously outstanding.

In connection with the issuance of any new Escrow Receipt under this Section 1.05, the Escrow Agent may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Pass Through Trustee and the Escrow Agent) connected therewith.

Any duplicate Escrow Receipt issued pursuant to this Section 1.05 shall constitute conclusive evidence of the appropriate Escrow Interest in the Account Amounts, as if originally issued, whether or not the lost, stolen or destroyed ▇▇▇▇▇▇ Receipt shall be found at any time.

The provisions of this Section 1.05 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Escrow Receipts.

Section 1.06. Additional Escrow Amounts. On the date of any Purchase Withdrawal, the Pass Through Trustee may re-deposit with the Depositary some or all of the amounts so withdrawn in accordance with Section 2.4 of the Deposit Agreement.

Section 1.07. Resignation or Removal of Escrow Agent. Subject to the appointment and acceptance of a successor ▇▇▇▇▇▇ Agent as provided below, the Escrow Agent may resign at any time by giving 30 days’ prior written notice thereof to the Investors, but may not otherwise be removed except for cause by the written consent of the Investors with respect to Investors representing Escrow Interests aggregating not less than a majority in interest in the Account Amounts (an “Action of Investors”). Upon any such resignation or removal, the Investors, by an Action of Investors, shall have the right to appoint a successor Escrow Agent. If no successor ▇▇▇▇▇▇ Agent shall have been so appointed and shall have accepted such appointment within 30 days after the retiring Escrow Agent’s giving of notice of resignation or the removal of the retiring Escrow Agent, then the retiring Escrow Agent may appoint a successor ▇▇▇▇▇▇ Agent. Any successor ▇▇▇▇▇▇ Agent shall be a bank or a trust company which has an office in the United States with a combined capital and surplus of at least $100,000,000. Upon the acceptance of any appointment as Escrow Agent hereunder by a successor ▇▇▇▇▇▇ Agent, such successor Escrow Agent shall enter into such documents as the Pass Through Trustee shall require and shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Escrow Agent, and the retiring Escrow Agent shall be discharged from its duties and obligations hereunder. No resignation or removal of the Escrow Agent shall be effective unless a written confirmation shall have been obtained from each of Fitch Ratings, Inc. and Standard & Poor’s Global Ratings, a Standard & Poor’s Financial Services LLC business, to the effect that the replacement of the Escrow Agent with the successor Escrow Agent will not result in (a) a reduction of the rating for the Certificates below the then current rating for the Certificates or (b) a withdrawal or suspension of the rating of the Certificates.

(American Airlines 2026-1 EETC)

Section 1.08. Persons Deemed Owners. Prior to due presentment of a Certificate for registration of transfer, the Escrow Agent and the Paying Agent may treat the Person in whose name any Escrow Receipt is registered (as of the day of determination) as the owner of such Escrow Receipt for the purpose of receiving distributions pursuant to this Agreement and for all other purposes whatsoever, and neither the Escrow Agent nor the Paying Agent shall be affected by any notice to the contrary.

Section 1.09. Further Assurances. Without limiting Sections 4 and 8 of this Agreement, the Escrow Agent agrees to take such actions, and execute such other documents, as may be reasonably requested by the Pass Through Trustee in order to effectuate the purposes of this Agreement, the Note Purchase Agreement or the Deposit Agreement and the performance by the Escrow Agent of its obligations hereunder or thereunder.

SECTION 2. Paying Agent.

Section 2.01. Appointment of Paying Agent. The Escrow Agent hereby irrevocably appoints and authorizes the Paying Agent to act as its paying agent hereunder, for the benefit of the Investors, for such specific purposes and with such powers as are specifically delegated to the Paying Agent by the terms of this Agreement, together with such other powers as are reasonably incidental thereto. Any and all money received and held by the Paying Agent under this Agreement or the Deposit Agreement shall be held in the Paying Agent Account for the benefit of the Investors. The Paying Agent (which term as used in this sentence shall include reference to its affiliates and its own and its affiliates’ officers, directors, employees and agents): (a) shall have no duties or responsibilities except those expressly set forth in this Agreement, and shall not by reason of this Agreement be a trustee for the Escrow Agent; (b) shall not be responsible for any recitals, statements, representations or warranties of any person other than itself contained in this Agreement or for the failure by the Escrow Agent or any other person or entity (other than the Paying Agent) to perform any of its obligations hereunder (whether or not the Paying Agent shall have any knowledge thereof); (c) may consult with legal counsel in connection with its duties hereunder and under the Deposit Agreement and shall be fully protected if any action taken, suffered or permitted by it is in good faith in accordance with the advice of counsel selected by it with due care; (d) shall not be responsible for any action taken or omitted to be taken by it hereunder or provided for herein or in connection herewith, except for its own willful misconduct or gross negligence (or simple negligence in connection with the handling of funds); and (e) shall in no event be liable for punitive, incidental or consequential damages.

Section 2.02. Establishment of Paying Agent Account. Upon the execution of this Agreement, the Paying Agent shall establish and maintain a segregated trust account (the “Paying Agent Account”) with the corporate trust department of Wilmington Trust Company in the name of the Escrow Agent, bearing a designation clearly indicating that the funds deposited therein are held in trust for the benefit of the Escrow Agent. It is expressly understood by the parties hereto that the Paying Agent is acting as the paying agent and trustee of the Escrow Agent hereunder and that no amounts on deposit in the Paying Agent Account constitute part of the Trust Property. The Paying Agent shall be under no obligation to invest any amounts held by it pursuant to the terms of this Agreement and the funds held in the Paying Agent Account shall not earn or accrue interest.

This Escrow Receipt evidences a fractional undivided interest in amounts (“Account Amounts”) from time to time deposited on behalf of the holder hereof into a certain paying agent account (the “Paying Agent Account”) described in the Escrow and Paying Agent Agreement (Class B) dated as of May 11, 2026 (as amended, modified or supplemented from time to time, the “Escrow and Paying Agent Agreement”) among Wilmington Trust, National Association, as Escrow Agent (in such capacity, together with its successors in such capacity, the “Escrow Agent”), ▇▇▇▇▇▇▇ ▇▇▇▇▇ & CO.

This Escrow Receipt is issued under and is subject to the terms, provisions and conditions of the Escrow and Paying Agent Agreement. By virtue of its acceptance hereof the holder of this Escrow Receipt assents and agrees to be bound by the provisions of the Escrow and Paying Agent Agreement and this Escrow Receipt.

This Escrow Receipt represents a fractional undivided interest in amounts deposited from time to time in the Paying Agent Account, and grants or represents no rights, benefits or interests of any kind in respect of any assets or property other than such amounts.

All payments and distributions made to the Receiptholders in respect of this Escrow Receipt shall be made only from Account Amounts deposited in the Paying Agent Account.

No Receiptholder of this Escrow Receipt shall have any right to vote on or in any manner otherwise control the operation and management of the Paying Agent Account, nor shall anything set forth herein, or contained in the terms of this Escrow Receipt, be construed so as to constitute the Receiptholders from time to time as partners or members of an association.
