I use US Airways a lot and I find the crews on the planes and at the counter to be about as friendly as I to them. I rely on a tight connection at Phoenix and rarely have a problem. I have a beef of no consequence in that I think the crews look sloppy and unkept but that a choice some corporate uniform czar made that I wish had shown more style. That said, the people in the uniforms have an unenviable job and generally do it acceptably.
