US Airways is a rip off. Get this: bought a ticket, then couldn't use it because work came up. Cancelled the flight. They provided a voucher/credit for use w/in 12 months.
Two days later, found a new flight for a week & 1/2 later. Called to use the voucher and was told there would be $150 change fee on top of the NEW much lower airfare. Hmmm...
After multiple discussions with various agents, was told that tho' there was a ticket for $175 less than the voucher, which I was looking at online at the moment, and I wanted to use the voucher for the amount PLUS the ridiculous change fee, which would leave me still paying another $25 (remember, I already paid $250 for the ticket I had to cancel), I was not allowed! Period. No discussion. Too bad.
WHY? Because the actual ticket price had to be equal to or more than the original ticket, plus pay the change fee. EVIL
