US Airways, should not be allowed to fly humans. Perhaps cargo.. Worst check in staff and worst air hostesses. They boarder dangerous, they are so incompetent. I would never fly with them again. If you want to ruin your holiday, fly US Airways. Flight 733 on 09/04/09 and flight 1660 on 17/04/09 by far rates for the most unhelpful, rude, down right useless ground and air crew I have ever had the displeasure of dealing with.
