passenger service employees said it has reached a tentative labor agreement with the bankrupt carrier.

In a release, the Communications Workers of America, which represents 6,000 US Airways reservation, gate and ticket agents, said it would send the agreement to its rank and file for a vote. The release did not provide details of the settlement.

"In the face of devastating demands for wage and benefit cuts and other concessions, the bargaining committee of CWA local union presidents and CWA staff was able to push back against some of the harsher and more excessive proposals made by US Airways management," the release said.

The airline confirmed the agreement, but also declined to provide details.

"We recognize the difficulty of this decision given the personal sacrifices that our CWA employees already have made, and we regret the industry conditions that require further changes to reduce costs," said Jerrold Glass, US Airways senior vice president of employee relations, in a statement. "But this agreement, coupled with our recent aircraft leasing and financing package, gives US Airways positive momentum toward a successful implementation of its Transformation Plan."

Earlier this week, the CWA board had authorized a strike should the airline get bankruptcy court approval to cancel its contracts. US Airways, which is in its second trip through bankruptcy in two years, has asked the judge overseeing its reorganization to cancel labor contracts with groups with which it is not able to reach consensual agreements.

US Airways has ratified agreements with the Air Line Pilots Association and three units of the Transport Workers Union. Negotiations continue with the Association of Flight Attendants (AFA) and the International Association of Machinists (IAM), mechanics and related, fleet service workers, and maintenance training specialists.

The AFA is in the midst of voting on whether to stage strikes should the judge cancel its contract.

US Airways shares finished Thursday's session up 9 cents, or 8.6%, at $1.14.
