FILE - In this June 23, 2008 file photo, a US Airways jet takes-off as an American Airlines Jet is prepped for takeoff at Sky Harbor International Airport in Phoenix. American Airlines says it is agreeing with creditors to consider potential mergers. AMR management has said for months that it wants American to emerge from bankruptcy protection as an independent airline, but that hasn't stopped US Airways, a smaller but profitable competitor, from trying to combine with American. US Airways has lined up support from American's three unions for a takeover. The unions believe that a combined company would cut fewer jobs and be more competitive with industry leaders United and Delta. (AP Photo/Matt York, File)
