Forward-Looking Statements

This Current Report on Form 8-K (including information included or incorporated by reference herein) includes “forward-looking statements” within the meaning of the safe harbor provisions of the United States Private Securities Litigation Reform Act of 1995.  Words such as “expect,’ “estimate,” “project,” “budget,” “forecast,” “anticipate,” “intend,” “plan,” “may,” “will,” “could,” “should,” “believes,” “predicts,” “potential,” “continue,” and similar expressions are intended to identify such forward-looking statements.  These forward-looking statements include, without limitation, Delta’s expectations with respect to the synergies, costs and charges, capitalization and anticipated financial impacts of the merger transaction and related transactions; approval of the merger transaction and related transactions by stockholders; the satisfaction of the closing conditions to the merger transaction and related transactions; and the timing of the completion of the merger transaction and related transactions.

These forward-looking statements involve significant risks and uncertainties that could cause the actual results to differ materially from the expected results. Most of these factors are outside our control and difficult to predict.  Factors that may cause such differences include, but are not limited to, the possibility that the expected synergies will not be realized, or will not be realized within the expected time period, due to, among other things, (1) the airline pricing environment; (2) competitive actions taken by other airlines; (3) general economic conditions; (4) changes in jet fuel prices; (5) actions taken or conditions imposed by the United States and foreign governments; (6) the willingness of customers to travel; (7) difficulties in integrating the operations of the two airlines; (8) the impact of labor relations; and (9) fluctuations in foreign currency exchange rates.  Other factors include the possibility that the merger does not close, including due to the failure to receive required stockholder or regulatory approvals, or the failure of other closing conditions.

Delta cautions that the foregoing list of factors is not exclusive. Additional information concerning these and other risk factors is contained in Delta’s and Northwest’s most recently filed Forms 10-K.  All subsequent written and oral forward-looking statements concerning Delta, Northwest, the merger, the related transactions  or other matters and attributable to Delta or Northwest or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements above. Delta and Northwest do not undertake any obligation to update any forward-looking statement, whether written or oral, relating to the matters discussed in this news release.

Additional Information About the Merger and Where to Find It

In connection with the proposed merger, Delta filed with the Securities and Exchange Commission (“SEC”) a Registration Statement on Form S-4 that includes a preliminary joint proxy statement of Delta and Northwest that also constitutes a prospectus of Delta.  At the appropriate time, Delta and Northwest will mail the final joint proxy statement/prospectus to their stockholders.  Delta and Northwest urge investors and security holders to read the final joint proxy statement/prospectus regarding the proposed merger when it becomes available because it will contain important information.  You may obtain copies of all documents filed with the SEC regarding this transaction, free of charge, at the SEC’s website (www.sec.gov).  You may also obtain these documents, free of charge, from Delta’s website (www.delta.com) under the tab “About Delta” and then under the heading “Investor Relations” and then under the item “SEC Filings.” You may also obtain these documents, free of charge, from Northwest’s website (www.nwa.com) under the tab “About Northwest” and then under the heading “Investor Relations” and then under the item “SEC Filings and Section 16 Filings.”

Delta, Northwest and their respective directors, executive officers and certain other members of management and employees may be soliciting proxies from Delta and Northwest stockholders in favor of the merger. Information regarding the persons who may, under the rules of the SEC, be deemed participants in the solicitation of Delta and Northwest stockholders in connection with the proposed merger will be set forth in the final proxy statement/prospectus when it is filed with the SEC. You can find information about Delta’s executive officers and directors in its definitive proxy statement filed with the SEC on April 25, 2008 related to Delta’s 2008 Annual Meeting of Stockholders.
