CINCINNATI – Elected union representatives for striking Comair pilots said Friday they would submit a proposed contract settlement to union members for a vote but are not endorsing the proposal.

The proposal from the National Mediation Board is not the result of a negotiated agreement, said J.C. Lawson, chairman of the Comair pilots’ unit of the Air Line Pilots Association.

“As such, this proposal is not endorsed by the pilots’ governing body,” he said.

Comair said later Friday that the airline would accept the settlement proposed by the board in order to end the strike that began March 26.

“This is a very serious decision with very serious ramifications,” Comair President Randy Rademacher said in a statement.

The airline declined to release details of the offer pending notification of all Comair pilots.

Negotiators narrowed differences during the bargaining session but failed to reach agreement, Lawson said.

He said, however, that union representatives were committed to giving members a voice in how to proceed. “In upcoming briefing sessions for our pilots, we will lay out the details of the proposal and the potential consequences of both its adoption and its rejection,” Lawson said.

The balloting period will end May 12, Lawson said.

Meanwhile, American Airlines said two days of mediated talks with its flight attendants ended without accord. The Association of Professional Flight Attendants, which represents 23,000 American attendants, has asked to be released from mediation without success.

American said in a statement it was disappointed that the talks did not result in a tentative agreement. The flight attendants have been working without a new contract for more than two years.

At Delta Air Lines, leaders of the pilots union have approved a new contract agreement and will put it to the rank-and-file for a vote beginning May 22. The vote by the 9,800 Delta pilots will last through June 20.

The walkout by Comair’s 1,350 pilots is costing owner Delta $3 million to $4 million a day in lost revenue. The company won’t disclose actual losses.
