Subject:    Promotional Support

Reference: Purchase Agreement No. 03776 (Purchase Agreement) between The Boeing
Company (Boeing) and United Airlines, Inc. (as assignee of United Continental
Holdings, Inc.) (Customer) relating to Model 737 *** aircraft (Aircraft)

This letter agreement (Letter Agreement) amends and supplements the Purchase
Agreement. This Letter Agreement supersedes and replaces in its entirety Letter
Agreement UAL-PA-03776-LA-1207646R1 dated December 13, 2013. All terms used but
not defined in this Letter Agreement shall have the same meaning as in the
Purchase Agreement.

Boeing and Customer wish to enter into an agreement pursuant to which each party
will contribute equally to promotional programs in support of the entry into
service of the Aircraft as more specifically provided below.

1.    Definitions.

1.1    Commitment Limit shall have the meaning set forth in Article 2, below.

1.2    Covered Aircraft shall mean those Aircraft identified on Table 1, Table
1.1 and
Table 1A to the Purchase Agreement as of the date of signing of this Letter
Agreement.

1.3 Performance Period shall mean the period beginning *** after the scheduled
delivery *** of the first Covered Aircraft. Customer requested, and Boeing
agreed to provide, *** of the Performance Period ***.

boeinglogoa01.jpg [boeinglogoa01.jpg]

Customer may request payment of any or all of such Promotional Support prior to
delivery of the first Covered Aircraft to Customer.

3.    Methods of Performance.

3.1 Subject to the Commitment Limit, Boeing will reimburse *** of Customer’s
payments of Qualifying Third Party Fees provided that Customer provides Boeing
copies of paid invoices for such Qualifying Third Party Fees no later than ***
after the delivery of the first Covered Aircraft.

3.2 Notwithstanding the above, at Customer’s request and subject to a mutually
agreed project, Boeing will provide certain Promotional Support during the
Performance Period directly to Customer. The full value of such Boeing provided
Promotional Support will be accounted for as part of the Commitment Limit and
will correspondingly reduce the amount of Qualifying Third Party Fees that are
subject to reimbursement pursuant to Article 3.1 above. Additionally, without
duplication the parties agree that the sum of *** (One-Time Non-Matching Promo
Support) shall be available to Customer on a one-time non-matching basis. For
the avoidance of doubt, the One-Time Non-Matching Promo Support shall be spent
on promotional activity selected at Customer’s discretion and shall be made

3.3 In the event Customer does not (i) utilize the full amount of the Commitment
Limit within the Performance Period or (ii) submit its paid invoices for
Qualifying Third Party Fees within the required time, as set forth in Article
3.1, Boeing shall have no further obligation to Customer for such unused
Commitment Limit or to *** Customer for such Qualifying Third Party Fees,
respectively.

4.    Project Approval.

Following the execution of this Letter Agreement, a Boeing Airline Marketing
Services representative will meet with Customer’s designated representative to
review and approve the extent, selection, scheduling, and *** process for the
Promotional Support to be provided pursuant to this Letter Agreement.

5.    Assignment.

Except as provided in Letter Agreement No. UAL-PA-03776-LA-1208238 the rights
and obligations described in this Letter Agreement are provided to Customer in
consideration of Customer’s becoming the operator of the Aircraft and cannot be
assigned in whole or, in part.

6.    Confidential Treatment.

Customer and Boeing understand that certain commercial and financial information
contained in this Letter Agreement are considered by Boeing and Customer as
confidential and are subject to the terms and conditions set forth in Letter
Agreement No. UAL-PA-03776-LA-

Subject:    Installation of Cabin Systems Equipment

Reference:    Purchase Agreement No. 03776 (Purchase Agreement) between The
Boeing
Company (Boeing) and United Airlines, Inc. (Customer) relating to Model 737
*** aircraft (Aircraft)

This letter agreement (Letter Agreement) amends and supplements the Purchase
Agreement. All terms used but not defined in this Letter Agreement shall have
the same meaning as in the Purchase Agreement.

Customer has requested that Boeing install in the Aircraft the In-Flight
Entertainment and communications systems (collectively referred to as Cabin
Systems Equipment or CSE) described in (i) Attachment A1 to this Letter
Agreement for the 737-*** Aircraft and (ii) Attachment A2 to this Letter
Agreement for the 737-*** Aircraft (Attachments A1 and A2 collectively referred
to herein as Attachment A). CSE is BFE that Boeing purchases for Customer and
that is identified in the Detail Specification for the applicable Aircraft.

1.    Customer Responsibilities.

1.1 For 737-*** Aircraft, Customer has already selected CSE suppliers
(Supplier(s)) system configuration and Options identified in Attachment A1 to
this Letter. For the 737-*** Aircraft, Customer will select Suppliers and system
configuration from among those identified in the Option(s) listed in Attachment
A2 to this Letter Agreement (Attachment A1 and Attachment A2 referred to
collectively as Attachment A), ***; or as otherwise available in the then
current Standard Selections Catalog and formally offered by Boeing.

1.2 Customer will enter into initial agreements with their selected Suppliers,
or otherwise cause the selected Suppliers, to actively participate with Customer
and Boeing in meetings, including but not limited to the Initial Technical
Coordination Meeting (ITCM), to ensure that Supplier's functional system
specifications meet Customer's and Boeing's respective requirements. Such
functional system specifications define functionality to which Boeing will test
prior to delivery but are not a guarantee of functionality at delivery.

1.3    Customer will enter into final agreements with the selected Suppliers
that will:

1.3.1 include the actual statement of work as defined at the ITCM. Final
agreements will also include price, warranty, training, product support
following Aircraft delivery (including spares support), and any other special
business arrangements required by Customer;

1.3.2 require Supplier to assist the seat suppliers in the preparation of seat
assembly functional test plans and procedures and coordinate integration
testing; and

1.3.3 require Supplier to comply with Boeing’s type design and type
certification data development and protection requirements where the Supplier
has type design/certification responsibility. The requirements will require
Suppliers to (i) maintain type design/certificate data for *** such type
certificate for all type design and (ii) entitle Boeing to access, review, and
receive such type design/certification data. These requirements will be provided
to Customer upon request.

2.    Boeing Responsibilities.

2.1    Boeing will:

2.1.1    perform the Project Manager functions stated in Attachment B;

2.1.2    provide Aircraft interface requirements to Suppliers;

2.1.3 assist Suppliers in the development of CSE system specifications and
approve such specifications;

2.1.4    release purchase orders, including on-dock dates to Supplier on behalf
of
Customer, and manage such purchase orders;

2.1.5    coordinate the resolution of technical issues with Suppliers;

2.1.6 ensure that at the time of Aircraft delivery the CSE configuration meets
the requirements of the Option(s) contained in Attachment A to this Letter
Agreement as such Attachment A may be amended from time to time; and

2.1.7    obtain FAA certification of the Aircraft with the conforming CSE
installed therein.

boeinglogoa01.jpg [boeinglogoa01.jpg]

3.    Software.

CSE systems may contain software of the following two types:

3.1    Certification Software. The software required to functionally test,
operate and certify the CSE systems on the Aircraft is the Certification
Software and is part of the CSE.

3.2    Customer's Software. The software which is defined by the Customer to
support specified features and appearance is Customer's Software and is not part
of the CSE.

3.2.1 Customer is solely responsible for specifying Customer's Software
functional and performance requirements and ensuring that Customer's Software
meets such requirements. Customer and Customer's Software supplier will have
total responsibility for the writing, certification, modification, revision, or
correction of any of Customer's Software. Boeing will not perform the functions
and obligations described in paragraph 1.2 above, or the Project Manager's
functions described in Attachment B, for Customer's Software.

3.2.2 The omission of any Customer's Software or the lack of any functionality
of Customer's Software will not be a valid condition for Customer's rejection of
the Aircraft at the time of Aircraft delivery unless such omission or lack of
functionality is due to a breach by Boeing of its obligations under this
Purchase Agreement.

3.2.3 Boeing has no obligation to approve any documentation to support
Customer's Software certification. Boeing will only review and operate
Customer's Software if in Boeing's reasonable opinion such review and operation
is necessary to certify the CSE on the Aircraft.

3.2.4    Boeing will not be responsible for obtaining FAA certification for
Customer's Software.

4.    Changes.

Any changes to CSE may only be made by and between Boeing and the Supplier.
Customer requested changes to the CSE specification after execution of this
Letter Agreement will be made in writing directly to Boeing for approval and for
coordination by Boeing with the Supplier. Any such change to the configuration
of the Aircraft will be subject to *** through Boeing’s master change or other
process for amendment of the Purchase Agreement. Any Supplier price increase or
decrease resulting from such change will be negotiated between Customer and
Supplier.

4.1 Boeing and Customer recognize that the developmental nature of the CSE may
require changes to the CSE or the Aircraft in order to ensure (i) compatibility
of the CSE with the Aircraft and all other Aircraft systems, and (ii) FAA
certification of the Aircraft with the CSE installed therein. In such event
Boeing will notify Customer and recommend to Customer

the most practical means for incorporating any such change. If *** after such
notification Customer and Boeing cannot mutually agree on the incorporation of
any such change or alternate course of action, the remedies available to Boeing
in Paragraph 6 will apply.

5. Supplier Defaults.

Boeing will notify Customer in a timely manner in the event of a default by a
Supplier under the Supplier's purchase order with Boeing. *** of Customer's
receipt of such notification, Boeing and Customer will agree on an alternate
Supplier or other course of action. If Boeing and Customer are unable to agree
on an alternate Supplier or course of action within such time, the remedies
available to Boeing in paragraph 6 will apply.

6. Exhibits B and C to the AGTA.

CSE is deemed to be BFE for the purposes of Exhibit B, Customer Support
Document, and Exhibit C, the Product Assurance Document, of the AGTA.

7.    Boeing’s Remedies.

If Customer does not perform its obligations as provided in this Letter
Agreement or if a Supplier fails (for any reason other than a default by Boeing
under the purchase order terms or this Letter Agreement) to deliver conforming
CSE per the schedule set forth in the purchase order, then, in addition to any
other remedies which Boeing may have by contract or under law, Boeing may:

7.1 revise the scheduled delivery month of the Aircraft to accommodate the delay
in delivery of the conforming CSE and base the calculation of the *** Adjustment
