I don't have a lot to share about my experience with US Airways. I like that they have wifi on most flights, but I don't have status on this airline vs. others so my experience is different. For the most part the staff is friendly and I have not had many delays that I can remember (with the exception of a recent trip). I generally fly US Airways to Phoenix from Houston and again think it meets most of my expectations.
I give it a two only because I have preferred status on other airlines so my experience is better on those airlines.
