Mesaba Airlines to become Northwest Airlines Subsidiary Under New Plan.

Regional Airline Files Its Plan of Reorganization with Bankruptcy Court 

MINNEAPOLIS & ST. PAUL, Minn. -- Mesaba Airlines, a subsidiary of MAIR Holdings, Inc. (NASDAQ:MAIR) announced today that it has signed a stock purchase and reorganization agreement with Northwest Airlines (Pink Sheets:NWACQ) under which Mesaba would become a wholly-owned subsidiary of Northwest Airlines, Inc.

Intensive negotiations with Northwest Airlines officials concluded this week with the boards for both Mesaba Aviation and MAIR Holdings, Inc. approving the deal.

"Mesaba now is positioned to form a new partnership with Northwest Airlines and meet the on-going challenges of the airline industry," Mesaba President and Chief Operating Officer John Spanjers said. "The support of Northwest and the cooperation of our first-rate, dedicated employees and our vendors have allowed us to use this process to lay the groundwork for Mesaba's future success."

The stock purchase and reorganization agreement is part of Mesaba's Plan of Reorganization (POR) that it filed today with the United States Bankruptcy Court for the District of Minnesota. The Company intends to file its related Disclosure Statement with the Court in the coming days.

"We have achieved exceptional results across the board during this restructuring process and today's filing represents a significant step toward a successful future for Mesaba," Spanjers said. "Our efforts will ensure that we emerge from Chapter 11 as a competitive regional carrier with a solid financial foundation and a continued focus on unmatched operational performance."

Mesaba intends to exit from Chapter 11 bankruptcy protection by the spring of this year.

In addition to the stock purchase and reorganization agreement, the POR addresses the treatment of creditors' claims and assumes the new agreements with Mesaba's labor groups and certain vendors and suppliers.

Restructuring Progress

Mesaba's comprehensive restructuring plan reduces costs by $68 million a year, secures its core business with Northwest for the 49 Saab 340Bs and positions the company for future growth opportunities. As a result of its on-going restructuring initiatives, the company has achieved reductions in its fixed costs, vendor costs, aircraft and engine leases, and labor costs.

"Mesaba employees have made a considerable sacrifice to achieve that cost structure," Spanjers said. "Our employees have exemplified the true commitment and professionalism that makes Mesaba the exceptional airline that it is."

Plan Highlights

Under the Stock Purchase and Reorganization Agreement with Northwest Airlines, all of the existing equity securities of Mesaba will be cancelled and terminated. Northwest has agreed that Mesaba has an allowed $145 million unsecured claim in Northwest's Chapter 11 case in exchange for 100 percent of Mesaba's new common stock to be issued on the effective date of the Plan. It is expected that the $145 million claim will be sold to fund the plan distributions to creditors, with the remainder of the sale proceeds being distributed to MAIR Holdings, Mesaba's parent.

Timing

The Plan is expected to become effective approximately two weeks after the Bankruptcy Court confirms the Plan. The confirmation hearing will be set by the Bankruptcy Court at a later point in time, but is expected to occur in mid-April 2007.
