The Allied Pilots Association (APA) board of directors has voted to reject a final contract offer from American Airlines, following similar decisions at the Association of Professional Flight Attendants (APFA) and Transport Workers Union (TWU).
The three unions will await a ruling from the US Bankruptcy Court for the Southern District of New York ruling on the Fort Worth, Texas-based carrier's section 1113 request to reject its labour contracts, which is expected on 22 June.
The APA board rejected the agreement by a five to 11 vote on 20 June. It says that it rejected the contract because of a "lack of specificity in various areas and the need for additional time to properly analyse various contractual provisions and related language."
American says it is "disappointed" that the pilots' union rejected the offer.
The failed agreement was the result of court mediated talks between American and the APA, as well as separate discussions with the APFA and TWU, ahead of the scheduled 1113 ruling.
American filed for chapter 11 bankruptcy protection in November 2011.
