American Airlines flight attendants demonstrate during a rally and march to save jobs at American Airlines and American Eagle, as hearings to void labor contracts begin at the U.S. Bankruptcy Court in New York in this April 23, 2012, file photo. Pilots at United Airlines and American Airlines are due to vote in coming weeks on new labor contracts that in some cases offer the first significant raises in almost a decade. But the carriers, citing high risks that the recovery in their fortunes could stall, are not prepared to improve contracts across the board, industry experts and airline executives say. That means labor relations could remain rocky. Flight attendants for U.S. Airways Group voted overwhelmingly last week to authorize a strike, saying their latest contract offer still reflects the days when airline profits were in free-fall.
