USAirways is a horrible airline. There're no two ways about it and it is now painfully clear to me why they are in bankruptcy (it was clear to me before from prior experiences -- only now is it painfully clear). I know not many people read this blog, but for those of you that do, I encourage you to avoid them like the plague.
Without getting into details (they're boring), USAir managed to get me into Montreal five hours late last night. Had I been a lemming, and followed the advice of their ticket agents, I'd be getting into Montreal at 3pm today. My flight was cancelled and they put everyone on a flight tomorrow INSTEAD OF THE FLIGHT LEAVING 3 HOURS LATER. How they thought this would be the best solution, I have no idea. Luckily, I was able to get on the later flight over the phone. Of course, by doing so, the ticket agent decided to cancel my flight back from Montreal, so I'm stuck here. That's now been rectified though, so don't worry.
Sorry to ramble. I don't know if that even made sense. If you take anything away from this post, it should be don't fly USAirways. If it's your only choice, rent a car, take a train, bus, anything. It is a terrible airline and deserves to go out of business.
Also, Montreal (what I've seen of it) seems to be pretty cool. I'll go explore now (that I'm off the phone with USAir (which took over an hour (roaming charges too (assholes (USAir, not Verizon))))).
