As I sit here in the plane in Vegas, I am completely and utterly pissed off at US Airways. My girlfriend and i were suppose to have a non-stop flight from Philadelphia to SFO. Instead the captain informed us that they were taking a few more "friends" with us and would need to be diverted to Vegas. This is a late flight as it is and they decided to be greedy and sell out the last few seats and not care that anyone will be over 2 hours late getting to SFO. It is ridiculous how the airline can just make this adjustment not due to weather and still charge the full amount for a non-stop flight and I'm pretty sure they charged a high premium for those "friends".
If you can avoid it, do not travel with them. Consistently delayed and now diverted?
