Contract talks between bankrupt American Airlines and its flight attendants union have broken off without a deal. The two sides have been trying to negotiate a new contract since 2008.
The Association of Professional Flight Attendants says the airline has insisted on "dramatic concessions" from it and other labor groups.
The AFPA maintains that American is making the wrong move in trying to exit bankruptcy on its own.
"I firmly believe a merger is the right move for this company," said APFA president Laura Glading in a written statement. "Our airline needs a network that can grow and compete with United and Delta. A strong company will provide more job security than even the best agreement American can offer as a standalone."
On Monday, the Fort Worth-based carrier is expected to start mediation talks with its pilots. In mid-May, American announced agreements with five workgroups represented by the Transport Workers Union.
A judge is expected to rule on the airline's bankruptcy case later this month.
