US Airways may be the worst airline right next to Spirit. I flew them to go to Burlington, VT for a wedding. On the return, our flight began announcing delays about 45 minutes before boarding. Fine, no problem. There were harsh storms back at home. We kept being told that there was a delay and the next announcment would be made in an hour. This happened 4 times. Once the lady got on and said "no new update, next update in 20 minutes." Finally, flight was cancelled after 4 hours. Everyone ran to the counter to rebook. They gave me a stand by flight. My friend ended up renting a car and driving 8.5 hours to be sure we would get out of there. They wouldn't even give us a free room. I've been told that US Airways' unofficial motto is "I'm sorry," because this is what they always say and never fix anything.
I will never fly them ever again. What a night mare to travel.
