REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ON INTERNAL CONTROL
OVER FINANCIAL
REPORTING
The Board of Directors and Stockholders of
Delta Air Lines, Inc.
We have audited Delta Air Lines, Inc.'s internal control over financial reporting as of December 31, 2012
, based on criteria established in Internal
Control-
Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Delta Air
Lines, Inc.'s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness
of internal control over financial reporting included in the accompanying Management's Annual Report on Internal Control Over Financial
Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was
maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting,
assessing the risk that a
material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing
such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial
reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's
internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable
detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions
are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts
and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3)
provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that
could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the
degree of compliance with the policies or procedures may deteriorate.
In our opinion, Delta Air Lines, Inc. maintained, in all material respects, effective internal control over financial reporting as of
December 31,
2012 , based on the COSO criteria.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated
balance sheets of Delta Air Lines, Inc. as of December 31, 2012 and 2011
, and the related consolidated statements of operations, comprehensive
income (loss), stockholders' (deficit) equity, and cash flows for each of the three years in the period ended December 31, 2012
of Delta Air Lines,
Inc. and our report dated February 12, 2013 expressed an unqualified opinion thereon.
