I am a Silver Preferred member on US Airways. This has gotten me the same lousy level of customer service representatives, the same lousy website (why do I need to call you to view my itinerary when the flight number changed?) as everyone.
I have few complaints about the flights, except they're expensive to fly direct from SFO to Pittsburgh, even though they're "a low cost carrier". The whole different check in line for flights from SFO to LAS/PHX and PIT/CLT /PHL is kinda weird too.
I'm through with you guys. The only time I'll fly US Airways is when I _need_ a direct flight to Pittsburgh.
