U.S. Airways Flight Attendant Carletta Farley yells slogans as she pickets with fellow attendants at Charlotte Douglas International Airport in Charlotte, North Carolina in this November 14, 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.
