Bankrupt carrier

Northwest Airlines

(NWACQ)

said it reached interim agreements with the Air Lines Pilots Association and the Professional Flight Attendants Association that would cut labor costs by a combined $332 million.

The pilots' union leadership agreed to temporary pay and other reductions of $215 million on an annualized basis. Flight attendants' leaders agreed to give up $117 million. The ALPA agreement requires membership ratification.

Northwest also said it signed tentative agreements on permanent wage and benefit reductions with workers represented by the Aircraft Technical Support Association and the Northwest Airlines Meteorology Association. The airline hopes to reach a deal with the Transport Workers Union of America shortly.

The airline didn't come to an interim pact with the heads of the International Association of Machinists and Aerospace Workers, and it has filed a motion with the U.S. Bankruptcy Court in New York asking for temporary wage and benefit reductions of $114 million from that union. Northwest is seeking a mid-November hearing date.

A statement on IAM Local 143's Web site said Northwest is asking the court to reduce the wages paid to the union's employees by 19% and the amount paid as sick pay to 75% of the prevailing wage rate, after taking into account the temporary pay reduction.

"The immediate sacrifice being asked from our members is unfortunate and regrettable," the IAM said. "Northwest's crisis took years to develop, and its problems will not be solved overnight. The IAM intends to utilize any additional time to obtain the best possible outcome for our members."

Minnesota-based Northwest, the world's fourth-largest airline, filed for bankruptcy in September. The carrier is trying to get $1.4 billion in labor concessions.
