Management's Annual Report on Internal Control Over Financial Reporting
Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is
defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. Our internal control over financial reporting is
designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for
external purposes in accordance with accounting principles generally accepted in the United States of America.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 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 may deteriorate.
Management conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2005
using the criteria issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control —
Integrated Framework. Based on that evaluation, management believes that our internal control over financial reporting was effective
as of December 31, 2005.
Management's assessment of the effectiveness of our internal control over financial reporting as of December 31, 2005 has been
audited by Deloitte & Touche LLP, an independent registered public accounting firm, which also audited our Consolidated Financial
Statements. Deloitte & Touche LLP's report on management's assessment of internal control over financial reporting is set forth
below.
Report of Independent Registered Public Accounting Firm
To the Board of Directors and Shareowners of Delta Air Lines, Inc.
Atlanta, Georgia
We have audited management's assessment, included in the accompanying Management's Annual Report on Internal Control over
Financial Reporting, that Delta Air Lines, Inc. (Debtor and Debtor-in-Possession) and subsidiaries (the "Company") maintained
effective internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control —
Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company'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. Our responsibility is to express an opinion on management's assessment and
an opinion on the effectiveness of 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, evaluating management's assessment, testing and evaluating the design and operating effectiveness of internal
control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a
reasonable basis for our opinions.
A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's principal
executive and principal financial officers, or persons performing similar functions, and effected by the company's board of directors,
management, and other personnel 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.
