MINNEAPOLIS (AP) _ Two days of mediated contract talks between Northwest Airlines and its pilots ended Thursday with no movement by either side and pilots continuing to push for an impasse to be declared.

Only the National Mediation Board can declare an impasse in the talks, which would set into motion a 30-day cooling off period required before pilots could strike.

No further talks were scheduled.

``They gave us no new proposals or counterproposals. We told the National Mediation Board that we thought the talks were at an impasse, that nothing would happen without a real deadline,'' said Paul Omodt, a spokesman for the Air Line Pilots Association.

``It's clear to us that the (management) people at the table have no authority to make a move and that their job is just to stall the talks as long as possible,'' Omodt said.

But Northwest management disagreed that talks are at an impasse.

``It is not in the best interests of the company or the passengers or any of our employees to have a strike,'' said spokeswoman Marta Laughlin. ``We will continue to pursue every means available to avoid a strike.''

Pilots have rejected Northwest's proposal for binding arbitration to settle the dispute. Pilot negotiators also rejected a proposal by Northwest last week that management said would have kept pilot compensation in line with that of pilots of other major carriers.

The latest round of talks were held Wednesday and Thursday in Washington, D.C.

The pilots and Northwest have been in contract negotiations since August 1996. Issues of pay, pensions, job protection and work rules still divide the two sides.

Northwest's other five unions also have open contracts. The International Association of Machinists votes on a tentative contract agreement with Northwest late this month.
