I fly US Airways often being based in Phoenix.
Service is ok and it's gate location in terminal 4 makes it great for parking in the economy east lot - $9 daily for uncovered and $11 daily for covered parking.
I also upgrade to first often especially for longer hauls when available.
Most recently I had a sub par experience with a chipped glass and spray paint mark on the arm rest.
Food options are not that great on the plane but terminal before boarding has some pretty decent options.
Love that they are part of one world alliance now.
