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.

MISCELLANEOUS PROVISIONS 

Section 10.01 Final Termination Date. The respective obligations and responsibilities of the Company and the Trustee created
hereby and the Class B Trust created hereby shall terminate upon the distribution to all Class B Certificateholders and the Trustee of 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 10.02 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 To the extent that any provisions of the Basic Agreement are superseded by any provisions of this Trust Supplement, any reference to such provisions of the Basic Agreement herein or in the Basic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 to such provisions of this Trust Supplement. 
 Section 10.03 Governing Law. THIS AGREEMENT HAS
BEEN DELIVERED IN THE STATE OF NEW YORK AND THIS AGREEMENT AND THE CLASS B CERTIFICATES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE. 

Section 10.04 Counterparts. This Trust Supplement may be executed in any number of counterparts (and each of the parties
shall not be required to execute the same counterpart). Each counterpart of this Trust Supplement including a signature page or pages executed by each of the parties hereto shall be an original counterpart of this Trust Supplement, but all of such
counterparts together shall constitute one instrument. 
 Section 10.05 Intention of Parties. The parties hereto intend that the
Class B Trust be classified for United States federal income tax purposes as a grantor trust under Subpart E, Part I, Subchapter J, Chapter 1 of Subtitle A of the Code, and not as a trust or association taxable as a corporation or as a
partnership. Each Certificateholder of, and each Person acquiring a beneficial interest in, a Class B Certificate, by its acceptance of its Class B Certificate or a beneficial interest therein, agrees to treat the Class B Trust as a grantor trust
for all United States federal, state and local income tax purposes. The Trustee shall not be authorized or empowered to do anything that would cause the Class B Trust to fail to qualify as a grantor trust for such tax purposes (including as subject
to this restriction, acquiring any Aircraft by bidding the Equipment Notes relating thereto or otherwise, or taking any action with respect to any such Aircraft once acquired). 

Section 10.06 Submission to Jurisdiction. Each of the parties hereto, to the extent it may do so under applicable law, for
purposes hereof and of all other Operative Agreements hereby (i) irrevocably submits itself to the non-exclusive jurisdiction of the courts of the State of New York sitting in the City of New York and to the non-exclusive jurisdiction of the
United States District Court for the Southern District of New York, for the purposes of any suit, action or other proceeding arising out of this Agreement, the subject matter hereof or any of the transactions contemplated hereby brought by any party
or parties hereto or thereto, or their successors or permitted assigns and (ii) waives, and agrees not to

assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit,
action or proceeding is improper or that this Agreement or the subject matter hereof or any of the transactions contemplated hereby may not be enforced in or by such courts. 

Section 10.07 Successor and Assigns. All covenants, agreements, representations and warranties in this Agreement by the Trustee
and the Company shall bind and, to the extent permitted hereby, shall inure to the benefit of and be enforceable by their respective successors and assigns, whether so expressed or not. Any request, notice, direction, consent, waiver or other
instrument or action by any Class B Certificateholder shall bind the successors and assigns of such Class B Certificateholder. 

Section 10.08 Normal Commercial Relations. Anything contained in this Agreement to the contrary notwithstanding, the Trustee and
any Class B Certificateholder, or any bank or other affiliate of any such party, may conduct any banking or other financial transactions, and have banking and other commercial relationships, with the Company fully to the same extent as if this
Agreement were not in effect, including without limitation the making of loans or other extensions of credit to the Company for any purpose whatsoever, whether related to any of the transactions contemplated hereby or otherwise. 

Section 10.09 No Recourse against Others. No past, present or future director, officer, employee, agent, member, manager, trustee
or stockholder, as such, of the Company or any successor Person shall have any liability for any obligations of the Company or any successor Person, either directly or through the Company or any successor Person, under the Class B Certificates or
this Agreement or for any claim based on, in respect of or by reason of such obligations or their creation, whether by virtue of any rule of law, statute or constitutional provision of by the enforcement of any assessment or by any legal or
equitable proceeding or otherwise. By accepting a Class B Certificate, each Class B Certificateholder agrees to the provisions of this Section 10.09 and waives and releases all such liability. Such waiver and release shall be part of the
consideration for the issue of the Class B Certificates. 
 Section 10.10 U.S.A. Patriot Act. The parties hereto acknowledge
that in accordance with Section 326 of the U.S.A. Patriot Act, the Trustee, like all financial institutions, in order to help fight the funding of terrorism and money laundering, is required to obtain, verify and record information that
identifies each person or legal entity that establishes a relationship or opens an account with the Trustee. Each party to this Trust Supplement agrees for itself that it will provide the Trustee with such information relating to such party as it
may reasonably request in order for the Trustee to satisfy the requirements of the U.S.A. Patriot Act.

 THIS CERTIFIES THAT
                    , for value received, is the registered owner of a $        
(         dollars) Fractional Undivided Interest (or such lesser amounts as shall be the aggregate outstanding face amount hereof as set forth in the records of the Trustee) in the Delta Air Lines Pass Through
Trust, Series 2015-1B (the “Trust”) created by U.S. BANK TRUST NATIONAL ASSOCIATION, as successor trustee (together with any successor in interest and any successor or other trustee appointed pursuant to the Trust Supplement referred
to below, the “Trustee”) under a Pass Through Trust Agreement, dated as of November 16, 2000 (the “Basic Agreement”), between U.S. Bank Trust National Association (as successor in interest to State Street Bank and Trust
Company of Connecticut, National Association) and Delta Air Lines, Inc., a Delaware corporation ( together with any successor in interest pursuant to Section 5.02 of the Basic Agreement, the “Company”), as supplemented by Trust
Supplement No. 2015-1B thereto dated as of August 24, 2015 (collectively, and as may be amended from time to time, the “Agreement”), between the Trustee and the Company, a summary of certain of the pertinent provisions of which
is set forth below. To the extent not otherwise defined herein, the capitalized terms used herein have the meanings assigned to them in the Agreement. This Certificate is one of the duly authorized Certificates designated as “Delta Air Lines
Pass Through Certificates, Series 2015-1B” (herein called the “Certificates”). This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement. By virtue of its acceptance hereof, the
Certificateholder of this Certificate assents to and agrees to be bound by all of the provisions of the Agreement and the Intercreditor Agreement, including the subordination provisions of Section 9.09 of the Intercreditor Agreement. The Trust
Property is expected to include certain Equipment Notes and includes all rights of the Trust and the Trustee, on behalf of the Trust, to receive any payments under the Intercreditor Agreement and the Class B Liquidity Facility. Each issue of the
Equipment Notes will be secured by, among other things, a security interest in the Aircraft owned by the Company. 
 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 30 and July 30 (each, a “Regular Distribution Date”), commencing on January 30, 2016, 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 B Equipment Notes due on such Regular Distribution Date, the receipt of which has been confirmed by the
Trustee, equal to the product of 
  

	1 	 To be included on the face of each Global Certificate. 








 
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 B 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 B 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 (or in the case of Global Certificates, send electronically in accordance
with DTC’s applicable procedures) notice of each Special Payment and the Special Distribution Date therefor to the Certificateholder of this Certificate. 

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 (or in the case of Global Certificates, sent electronically in accordance with DTC’s applicable
procedures) 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 Registrar, or by any successor Registrar, duly endorsed or
accompanied by a written instrument of transfer in form satisfactory to the Trustee and the Registrar, duly executed by the Certificateholder hereof or such Certificateholder’s attorney duly authorized in writing, and thereupon one or more new
Certificates of authorized denominations evidencing the same aggregate Fractional Undivided Interest in the Trust will be issued to the designated transferee or transferees. 

The Certificates are issuable only as registered Certificates without coupons in minimum denominations of $2,000 (or such other denomination
that is the lowest integral multiple of $1,000 that is, at the time of issuance, equal to at least 1,000 euros) Fractional Undivided Interest and integral multiples of $1,000 in excess thereof except that one Certificate may be issued in a different
denomination. As provided in the Agreement and subject to certain limitations therein set forth, the Certificates are exchangeable for new Certificates of authorized denominations evidencing the same aggregate Fractional Undivided Interest in the
Trust, as requested by the Certificateholder surrendering the same. 
 No service charge will be made for any such registration of transfer
or exchange, but the Trustee shall require payment of a sum sufficient to cover any tax or governmental charge payable in connection therewith. 

The Company, the Trustee, the Registrar and any Paying Agent shall deem and treat the Person in whose name this Certificate is registered as
the owner hereof for all purposes, and none of the Company, the Trustee, the Registrar or any such agent shall be affected by any notice to the contrary. 

Each Certificateholder and Person with a beneficial interest herein, by its acceptance of this Certificate or such interest, agrees to treat
the Trust as a grantor trust for all U.S. federal, state and local income tax purposes. 
 The obligations and responsibilities created by
the Agreement and the Trust created thereby shall terminate upon the distribution to Certificateholders of all amounts required to be distributed to them pursuant to the Agreement and the disposition of 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
(a) 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 purchase or hold 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 or more prohibited transaction
statutory or administrative exemptions or similar exemptions under Similar Law and (b) direct the Trustee to invest the assets held in the Trust pursuant to, and take all other actions contemplated by, the terms and conditions of the Basic
Agreement, this Trust Supplement, the Intercreditor Agreement and each Participation Agreement. 
 THIS CERTIFICATE AND THE AGREEMENT
SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE. 

Unless the certificate of authentication hereon has been executed by the Trustee, by manual signature, this Certificate shall not be entitled
to any benefit under the Agreement or be valid for any purpose. 






 IN WITNESS WHEREOF, the Trustee has caused this Certificate to be duly executed.
