Flight attendants at US Airways voted down a tentative agreement that would have been their first joint contract since the merger with America West in 2005.
The deal was rejected by 75 percent of 5,832 voting flight attendants, according to their union.
America West bought the old US Airways out of bankruptcy protection in 2005 to form the current US Airways Group Inc. But flight attendants and pilots have both continued to operate under separate contracts.
Both groups are covered by separate units of the Association of Flight Attendants-CWA. A joint negotiating committee had unanimously recommended approval of the deal.
“We believe that to get more money out of this company would require a strike,” which is difficult under federal labor rules, the committee wrote to workers on March 20.
But the next day, the council that runs the part of the union for pre-merger US Airways flight attendants ousted longtime president Mike Flores, apparently over his strong support for the deal.
