United Air flight attendants reject wage cuts Friday June 21, 1:35 PM EDT CHICAGO, June 21 (Reuters) - Union leadership for flight attendants at UAL Corp.'s (UAL) United Airlines has rejected a 5 percent wage cut, as expected, endangering a deal in which the pilots' union accepted lower pay in return for stock options in the struggling airline. In a resolution posted on the Association of Flight Attendants Web site, the union said the proposal is concessionary and "not in the best interest of the flight attendant carrier." A deal with pilots reached earlier in the week to cut wages by 10 percent requires participation of other unions, according to pilot spokesman Steve Derebey. Both machinists and flight attendants have repeatedly said they would not talk to the airline about wage cuts. Roger EWROPS
