beneficial owners thereof pursuant to paragraph (b) of this Section 4.03, such Global Certificate or Global Exchange Certificate shall be deemed to be surrendered to the Trustee for cancellation, and the Trustee shall execute, authenticate

clause (i) above and instructions given in accordance with DTC’s and the Registrar’s procedures therefor, the Registrar shall reflect on its books and records the date of such transfer and an increase in the principal amount of Global

(c) [Reserved]

compliance with the provisions of the Securities Act.

and any interest therein only as provided in this Trust Supplement. The Registrar shall not register a transfer of any Class A Certificate unless such transfer complies with the restrictions on transfer of such Class A Certificate set

certifications, legal opinions or other information as either of them may reasonably require to confirm that such transfer is being made pursuant to an exemption from, or a transaction not subject to, the registration requirements of the Securities
Act and in accordance with the terms and provisions of this Article IV of this Trust Supplement; provided that the Registrar and the Trustee shall not be required to determine the sufficiency of any such certifications, legal opinions or other
information and shall be fully protected in relying thereon.

communications at any reasonable time upon the giving of reasonable written notice to the Registrar.

Rating. Each Holder of Class A Certificates agrees that if the Class A Certificates do not have an Investment Grade Rating and such Holder is (i) an affiliate of American or the Class A Trust, or a broker-dealer selling or
otherwise transferring Class A Certificates acquired directly from American for its own account, or (ii) an underwriter as defined in section 2(a)(11) of the Securities Act, such Holders (a) may not resell or otherwise transfer such
Class A Certificates under a Shelf Registration Statement and (b) may only offer, sell or otherwise transfer such Class A Certificates to QIBs.

transfers and exchanges of such Class A Certificates as herein provided. The Trustee shall initially be the registrar (the “Registrar”) for the purpose of registering such Class A Certificates and transfers and exchanges
of such Class A Certificates as herein provided. Promptly upon the Trustee’s request therefor, (a) the Registrar shall provide to the Trustee a true and complete copy of the Register, and (b) the Registrar shall provide to the
Trustee such information regarding the Class A Certificates and the Class A Certificateholders as is reasonably available to the Registrar. 
 All Class A Certificates issued upon any registration of transfer or exchange of Class A Certificates shall be valid obligations of the Trust, evidencing the same interest therein, and entitled
to the same benefits under this Agreement, as the Class A Certificates surrendered upon such registration of transfer or exchange. 
 Upon surrender for registration of transfer of any Class A Certificate at the Corporate Trust Office or such other office or agency designated by the Registrar with the form of transfer notice
thereon duly completed and executed, and otherwise complying with the terms of this Agreement, including providing evidence of compliance with any restrictions on transfer, in form satisfactory to the Trustee, the Registrar and the Company, the
Trustee shall execute, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Class A Certificates, in authorized denominations of a like aggregate Fractional Undivided Interest. Whenever any
Class A Certificates are surrendered for exchange, the Trustee shall execute, authenticate and deliver the Class A Certificates that the Class A Certificateholder making the exchange is entitled to receive. Every Class A
Certificate presented or surrendered for registration of transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Trustee and the Registrar duly executed by the Class A
Certificateholder thereof or its attorney duly authorized in writing. The Registrar and/or the Trustee may request and shall be entitled to receive as a prerequisite to the registration of transfers of any Class A Certificate in connection with

has so notified the Trustee and the Registrar in writing of such satisfaction. The Registrar and the Trustee shall not be liable to any Person for registering any transfer or exchange, or for executing, authenticating or delivering any Class A

Class A Certificate.

restrictions hereof, the Trustee shall execute and authenticate Class A Certificates at the Registrar’s request. No service charge shall be made to a Class A Certificateholder for any registration of transfer or exchange of
Class A Certificates, but the Trustee and the Registrar shall require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Class A Certificates. All
Class A Certificates surrendered for registration of transfer or exchange shall be canceled and subsequently destroyed by the Trustee. Notwithstanding anything contained herein or elsewhere to the contrary, neither the Registrar nor the Trustee

purchase all, but not less than all, of the Class A Certificates and the Class B Certificates pro rata based on the Fractional Undivided Interest in the Additional Trust held by each such Additional Certificateholder and (B) upon
consummation of such purchase no Additional Certificateholder shall have a right to purchase the Class A Certificates and the Class B Certificates pursuant to this Section 6.01(a)(ii) during the continuance of such Certificate Buy-Out
Event; and 
 (iii) if any Refinancing Certificates are issued, each Refinancing Certificateholder shall have the
same right (subject to the same terms and conditions) to purchase Certificates pursuant to this Section 6.01(a) (and to receive notice in connection therewith) as the Holders of the Class that such Refinancing Certificates refinanced.

 The purchase price with respect to the Class A Certificates shall be equal to the Pool Balance of the Class A
Certificates, together with accrued and unpaid interest in respect thereof to the date of such purchase, and any other amounts then due and payable to the Class A Certificateholders under this Agreement, the Intercreditor Agreement, the Escrow
Agreement, any Series A Equipment Note held as the property of the Class A Trust or the related Indenture and Participation Agreement or on or in respect of the Class A Certificates but without any Premium, provided, however,
that if such purchase occurs after (x) a record date specified in Section 2.03 of the Escrow Agreement relating to the distribution of unused Deposits and/or accrued and unpaid interest on Deposits and prior to or on the related
distribution date under the Escrow Agreement, such purchase price shall be reduced by the aggregate amount of unused Deposits and/or interest to be distributed under the Escrow Agreement (which deducted amounts shall remain distributable to, and may
be retained by, the Class A Certificateholders as of such record date) or (y) the Record Date relating to any Distribution Date, such purchase price shall be reduced by the amount to be distributed hereunder on such related Distribution
Date (which deducted amounts shall remain distributable to, and may be retained by, the Class A Certificateholders as of such Record Date); provided, further, that no such purchase of Class A Certificates pursuant to this
Section 6.01(a) shall be effective unless the purchaser(s) shall certify to the Trustee that contemporaneously with such purchase, such purchaser(s) is purchasing, pursuant to the terms of this Agreement, the Class B Trust Agreement, the
Additional Trust Agreement (if any) or the applicable Refinancing Trust Agreement (as the case may be), and the Intercreditor Agreement, all of the Class A Certificates, the Class B Certificates and, if applicable, the Refinancing Certificates
that are senior to the securities held by such purchaser(s). Each payment of the purchase price of the Class A Certificates referred to in the first sentence of this paragraph shall be made to an account or accounts designated by the Trustee
and each such purchase shall be subject to the terms of this Section 6.01(a). Each Class A

Certificateholder agrees by its acceptance of its Class A Certificate that it will, upon payment from such Class B Certificateholder(s), Additional Certificateholder(s) or Refinancing
Certificateholder(s), as the case may be, of the purchase price set forth in the first sentence of this paragraph, forthwith sell, assign, transfer and convey to the purchaser(s) thereof (without recourse, representation or warranty of any kind
except as to its own acts) all of the right, title, interest and obligation of such Class A Certificateholder in this Agreement, the Escrow Agreement, the Deposit Agreement, the Intercreditor Agreement, the Class A Liquidity Facility, the
NPA, the Note Documents and all Class A Certificates and Escrow Receipts held by such Class A Certificateholder (excluding all right, title and interest under any of the foregoing to the extent such right, title or interest is with respect
to an obligation not then due and payable as respects any action or inaction or state of affairs occurring prior to such sale) and the purchaser(s) shall assume all of such Class A Certificateholder’s obligations under this Agreement, the
Escrow Agreement, the Deposit Agreement, the Intercreditor Agreement, the Class A Liquidity Facility, the NPA, the Note Documents and all such Class A Certificates and Escrow Receipts. The Class A Certificates will be deemed to be
purchased on the date payment of the purchase price is made notwithstanding the failure of any Class A Certificateholder to deliver any Class A Certificate and, upon such a purchase, (i) the Class A Certificateholders shall have
no further rights with respect to the Class A Certificates and (ii) if the purchaser(s) shall so request, each such Class A Certificateholder will comply with all the provisions of Section 3.04 of the Basic Agreement and the
applicable provisions of this Trust Supplement to enable new Class A Certificates to be issued to the purchaser(s) in such denominations otherwise authorized under this Agreement as it shall request. All charges and expenses in connection with
the issuance of any such new Class A Certificates shall be borne by the purchaser(s) thereof. 
 (b) This Section 6.01
supplements and, to the extent inconsistent with any provision of Section 6.01(d) of the Basic Agreement, replaces the provisions of Section 6.01(d) of the Basic Agreement. Notwithstanding anything to the contrary set forth herein or in
any Operative Agreement, the provisions of this Section 6.01 may not be amended in any manner without the consent of each Class A Certificateholder, Class B Certificateholder and Additional Certificateholder or, as the case may be,
Refinancing Certificateholder (in each case, other than the Company or any of its Affiliates in its respective capacity as a Certificateholder) that would be adversely affected thereby; provided that the purchase price under this
Section 6.01 (as in effect on the date hereof) for any Certificate held by the Company or any of its Affiliates shall not be modified without the prior written consent of the Company. For the avoidance of doubt, if a Certificate Buy-Out Event
ceases to exist and another Certificate Buy-Out Event occurs and is continuing, the purchase rights set forth in Section 6.01(a) shall be revived notwithstanding any exercise of such rights during the continuance of any preceding Certificate
Buy-Out Event.

or waiver of the closing conditions specified in the Certificate Purchase Agreement, the Trustee shall execute, deliver, authenticate, issue and sell Class A Certificates in authorized
denominations equaling in the aggregate the amount set forth, with respect to the Class A Trust, in Schedule A to the Certificate Purchase Agreement evidencing the entire ownership interest in the Class A Trust, which amount equals the
maximum aggregate principal amount of Series A Equipment Notes which may be purchased from time to time by the Trustee pursuant to the NPA. Except as provided in Sections 3.03, 3.05 and 3.06 of the Basic Agreement, Sections 4.03, 4.04 and 4.05 of
this Trust Supplement or upon exchange of the Initial Certificates for Exchange Certificates, the Trustee shall not execute, authenticate or deliver Class A Certificates in excess of the aggregate amount specified in this paragraph. The
provisions of this Section 7.01(a) supersede and replace the first three sentences of Section 2.02(a) of the Basic Agreement and the first sentence of Section 3.02(a) of the Basic Agreement, with respect to the Class A Trust.

 (b) On or after the Issuance Date, the Company may deliver from time to time, and in accordance with Section 1(b) of the
NPA, to the Trustee a Funding Notice relating to one or more Series A Equipment Notes. After receipt of such a Funding Notice and in any case no later than one Business Day prior to a Funding Date as to which such Funding Notice relates (the
“Applicable Funding Date”), the Trustee shall (as and when specified in the Funding Notice) deliver to the Escrow Agent the Withdrawal Certificates and related Applicable Notices of Purchase Withdrawal, as contemplated by
Section 1.02(c) of the Escrow Agreement and by such Funding Notice. The Trustee shall (as and when specified in such Funding Notice), subject to the conditions set forth in Section 2 of the NPA, enter into and perform its obligations under
the Participation Agreement specified in such Funding Notice (the “Applicable Participation Agreement”) and cause such certificates, documents and legal opinions relating to the Trustee to be duly delivered as required by the
Applicable Participation Agreement. If at any time prior to the Applicable Funding Date, the Trustee receives from the Company a notice pursuant to the first sentence of Section 1(f) of the NPA, then the Trustee shall give notice to the
Depositary (with a copy to the Escrow Agent) of the cancellation of such Notice of Purchase Withdrawal relating to such Deposit or Deposits on such Applicable Funding Date as contemplated by Section 2.3 of the Deposit Agreement. Upon
satisfaction of the conditions specified in the NPA and the Applicable Participation Agreement, the Trustee shall purchase the applicable Series A Equipment Notes with the proceeds of the withdrawals of one or more Deposits made on the Applicable
Funding Date in accordance with the terms of the Deposit Agreement and the Escrow Agreement. The purchase price of such Series A Equipment Notes shall equal the principal amount of such Series A Equipment Notes. Amounts withdrawn from such Deposit
or Deposits in excess of the purchase price of the Series A Equipment Notes or to the extent not applied on the Applicable Funding Date to the purchase price of the Series A Equipment Notes shall be re-deposited by the Trustee with the Depositary on
the Applicable Funding Date in accordance with the terms of the Deposit Agreement. The provisions of this Section 7.01(b) supersede and replace the provisions of Section 2.02 of the Basic Agreement with respect to the Class A Trust,
and no provisions of the Basic Agreement relating to Postponed Notes and Section 2.02 of the Basic Agreement shall apply to the Class A Trust. 
 (c) With respect to the Class A Trust, Section 4.01(b) of the Basic Agreement is superseded and replaced in its entirety with the following: “The Trustee shall establish and maintain on
behalf of the Class A Certificateholders a Special Payments Account as one or more accounts, which shall be non-interest bearing except as provided in Section 4.04 of the Basic

Agreement. The Trustee shall hold the Special Payments Account in trust for the benefit of the Class A Certificateholders and shall make or permit withdrawals therefrom only as provided in
the Agreement or the Intercreditor Agreement. On each day when one or more Special Payments are made to the Trustee under the Intercreditor Agreement, the Trustee, upon receipt thereof, shall immediately deposit the aggregate amount of such Special
Payments in the Special Payments Account.” 
 (d) With respect to the Class A Trust, the second sentence of
Section 4.02(c) of the Basic Agreement shall be superseded and replaced in its entirety with the following sentence: “Subject to the provisions of the Intercreditor Agreement: (i) in the event of redemption or purchase of Series A
Equipment Notes held in the Class A Trust, such notice shall be mailed not less than 15 days prior to the Special Distribution Date for the Special Payment resulting from such redemption or purchase, which Special Distribution Date shall be the
date of such redemption or purchase; and (ii) in the case of any other Special Payments, such notice of Special Payment shall be mailed as soon as practicable after the Trustee has confirmed that it has received funds for such Special Payment
and shall state the Special Distribution Date for such Special Payment, which shall occur 15 days after the date of such notice of Special Payment or (if such 15th day is not practicable) as soon as practicable thereafter.” 

(e) With respect to the Class A Trust, clause (ii) of the third sentence of Section 4.02(c) of the Basic Agreement shall be
amended by deleting in its entirety the parenthetical phrase “(taking into account any payment to be made by the Responsible Party pursuant to Section 2.02(b)).” 

Section 7.02 Withdrawal of Deposits. If any Deposits remain outstanding on the Business Day next succeeding the Cut-off Date,
the Trustee shall promptly give the Escrow Agent notice, as contemplated by clause (ii) of Section 1.02(f) of the Escrow Agreement, that the Trustee’s obligation to purchase Series A Equipment Notes under the NPA has terminated and
the Cut-off Date has occurred. 
 Section 7.03 The Trustee. (a) Subject to Section 7.04 of this Trust
Supplement and Section 7.15 of the Basic Agreement, the Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Trust Supplement, the Intercreditor Agreement, the Deposit Agreement, the
NPA or the Escrow Agreement or the due execution hereof or thereof by the Company or the other parties thereto (other than the Trustee), or for or in respect of the recitals and statements contained herein or therein, all of which recitals and

Intercreditor Agreement, the NPA and the Escrow Agreement has been executed and delivered by one of its officers who is duly authorized to execute and deliver such document on its behalf. 

(b) The Trustee shall at all times be a bank or trust company, organized and doing business under the laws of the United States or any
state thereof, a substantial part of the business of which consists of (i) receiving deposits and making loans or (ii) exercising fiduciary powers similar to those permitted to national banks by the Comptroller of the Currency, and which

all amounts required to be distributed to them pursuant to this Agreement and the disposition of all property held as part of the Trust Property; provided, however, that in no event
shall the Trust created hereby continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Joseph P. Kennedy, Sr., the father of John F. Kennedy, former President of the United States, living on the date of
this Trust Supplement. 
 Section 9.02 Basic Agreement Ratified. Except and so far as herein expressly provided, all
of the provisions, terms and conditions of the Basic Agreement are in all respects ratified and confirmed; and the Basic Agreement and this Trust Supplement shall be taken, read and construed as one and the same instrument. To the extent that any
provisions of the Basic Agreement are superseded by any provisions of this Trust Supplement, any reference to such provisions of the Basic Agreement herein or in the Basic Agreement shall be deemed to be such provisions of this Trust Supplement.

 Section 9.03 Governing Law. THIS AGREEMENT HAS BEEN DELIVERED IN THE STATE OF NEW YORK AND THIS AGREEMENT AND THE

any Aircraft by bidding the Equipment Notes relating thereto or otherwise, or taking any action with respect to any such Aircraft once acquired).

 The Certificates represent Fractional Undivided Interests in the Trust and the Trust
Property, and will have no rights, benefits or interest in respect of any other separate trust established pursuant to the terms of the Basic Agreement for any other series of certificates issued pursuant thereto. 

Subject to and in accordance with the terms of the Agreement and the Intercreditor Agreement, from funds then available to the Trustee,
there will be distributed on each January 15 and July 15 (each, a “Regular Distribution Date”), commencing on July 15, 2013, to the Person in whose name this Certificate is registered at the close of business on the
15th day preceding the Regular Distribution Date, an amount in respect of the Scheduled Payments on the Series A Equipment Notes due on such Regular Distribution Date, the receipt of which has been confirmed by the Trustee, equal to the product of
the percentage interest in the Trust evidenced by this Certificate and an amount equal to the sum of such Scheduled Payments. Subject to and in accordance with the terms of the Agreement and the Intercreditor Agreement, in the event that Special
Payments on the Series A Equipment Notes are received by the Trustee, from funds then available to the Trustee, there shall be distributed on the applicable Special Distribution Date, to the Person in whose name this Certificate is registered at the
close of business on the 15th day preceding the applicable Special Distribution Date, an amount in respect of such Special Payments on the Series A Equipment Notes, the receipt of which has been confirmed by the Trustee, equal to the product of the
percentage interest in the Trust evidenced by this Certificate and an amount equal to the sum of such Special Payments so received. If a Regular Distribution Date or Special Distribution Date is not a Business Day, distribution shall be made on the
immediately following Business Day and no interest shall accrue during the intervening period. The Trustee shall mail notice of each Special Payment and the Special Distribution Date therefor to the Certificateholder of this Certificate. 

The Holder of this Certificate is entitled to the benefits of the Registration Rights Agreement, dated as of
March 12, 2013, among the Company, the Trustee and the representatives of the Initial Purchasers named therein (the “Registration Rights Agreement”). Subject to the terms of the Registration Rights Agreement, in the event that
neither the consummation of the Exchange Offer nor the declaration by the Commission of a Shelf Registration Statement to be effective (a “Registration Event”) occurs on or prior to the 90th day after the Exchange Deadline (as defined below) (or, if the last
day of such 90th day period is not a Business Day, the
first Business Day thereafter) (the “Shelf Registration Deadline”), the interest rate per annum borne by the Certificates shall be increased by 0.50% per annum effective as of the first day after the Shelf Registration Deadline
but only until the Exchange Offer is consummated or the Shelf Registration Statement is declared or otherwise becomes effective under Securities and Exchange Commission rules. In the event that the Shelf Registration Statement ceases to be available
at any time in the manner prescribed and during the period specified by the Registration Rights Agreement for more than 45 days during any three-month period or 120 days within any one-year period, the interest rate per annum borne by the
Certificates shall be increased by 0.50% from the 46th day
or 121st day, as applicable, until such time as the Shelf
Registration Statement again becomes available. The “Exchange Deadline” means the 270th day after the Plan Effective Date (or, if the last day of such 270-day period is not a Business Day, the first Business Day thereafter).2

 Distributions on this Certificate will be made by the Trustee by check mailed to the Person
entitled thereto, without the presentation or surrender of this Certificate or the making of any notation hereon, except that with respect to Certificates registered on the Record Date in the name of a Clearing Agency (or its nominee), such
distributions shall be made by wire transfer. Except as otherwise provided in the Agreement and notwithstanding the above, the final distribution on this Certificate will be made after notice mailed by the Trustee of the pendency of such
distribution and only upon presentation and surrender of this Certificate at the office or agency of the Trustee specified in such notice. 
 The Certificates do not represent a direct obligation of, or an obligation guaranteed by, or an interest in, the Company, the Trustee, the Subordination Agent, any Loan Trustee or any Affiliate of any
thereof. The Certificates are limited in right of payment, all as more specifically set forth on the face hereof and in the Agreement. All payments or distributions made to Certificateholders under the Agreement shall be made only from the Trust
Property and only to the extent that the Trustee shall have sufficient income or proceeds from the Trust Property to make such payments in accordance with the terms of the Agreement. Each Certificateholder of this Certificate, by its acceptance
hereof, agrees that it will look solely to the income and proceeds from the Trust Property to the extent available for any payment or distribution to such Certificateholder pursuant to the terms of the Agreement and that it will not have any
recourse to the Company, the Trustee, the Loan Trustees or any Affiliate of any thereof except as otherwise expressly provided in the Agreement, in any Note Document or in the Intercreditor Agreement. This Certificate does not purport to summarize
the Agreement and reference is made to the Agreement for information with respect to the interests, rights, benefits, obligations, proceeds and duties evidenced hereby. A copy of the Agreement may be examined during normal business hours at the
principal office of the Trustee, and at such other places, if any, designated by the Trustee, by any Certificateholder upon request. 
 The Agreement permits, with certain exceptions therein provided, the amendment thereof, and the modification of the rights and obligations of the Company and the rights of the Certificateholders under the
Agreement, at any time by the Company and the Trustee with the consent of the Certificateholders holding Certificates evidencing Fractional Undivided Interests aggregating not less than a majority in interest in the Trust. Any such consent by the
Certificateholder of this Certificate shall be conclusive and binding on such Certificateholder and upon all future Certificateholders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange hereof or in lieu hereof
whether or not notation of such consent is made upon this Certificate. The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Certificateholders of any of the Certificates. 

As provided in the Agreement and subject to certain limitations set forth therein, the transfer of this Certificate is registrable in the
Register upon surrender of this Certificate for registration of transfer at the offices or agencies maintained by the Trustee in its capacity as

interest, agrees to treat the Trust as a grantor trust for all U.S. federal, state and local income tax purposes.

all property held as part of the Trust Property. 
 Any Person acquiring or accepting this Certificate or an interest herein
will, by such acquisition or acceptance, be deemed to represent and warrant to the Company, the Loan Trustees and the Trustee that either: (i) no assets of a Plan or any trust established with respect to a Plan have been used to acquire this
Certificate or an interest herein or (ii) the purchase and holding of this Certificate or interest herein by such Person are exempt from the prohibited transaction restrictions of ERISA and the Code or provisions of Similar Law pursuant to one
