Item 8.01 Other Events

Pinnacle Airlines, Inc. (“Pinnacle”), a wholly owned subsidiary of Pinnacle Airlines Corp. (the “Company”), provides regional airline service to Northwest Airlines, Inc. (“Northwest”) under an Amended and Restated Airline Services Agreement that was effective January 1, 2007 (the “ASA”).

The ASA contains a provision that required Pinnacle and the Airline Pilots Association (“ALPA”) to reach a new collective bargaining agreement by March 31, 2007 to retain the 17 CRJ aircraft scheduled to be delivered to Pinnacle in 2007 on a long-term basis. Because Pinnacle and ALPA did not reach agreement by March 31, 2007, Northwest has given Pinnacle notice that it intends to transition the 15 aircraft delivered in the first quarter of 2007 to one of Northwest’s wholly owned subsidiaries expected to begin in September 2007 at a rate of two aircraft per month. In addition, Pinnacle will not receive the two remaining aircraft originally scheduled to be delivered in 2007. Upon completion of this transition, Pinnacle will operate a fleet of 124 CRJ-200 aircraft under the ASA (subject to further adjustment under certain circumstances as provided for in the ASA).

Because these aircraft were not committed to Pinnacle on a long-term basis, Pinnacle is entitled to the full amount of its stipulated unsecured claim in the Northwest bankruptcy proceedings. The Company still retains $42.5 million of this unsecured claim, and may monetize it in the near future. Any sale of this remaining claim would be treated as deferred revenue and amortized into operating revenue over the remaining term of the ASA.
