I think this may be one of the times when you see a lot of airlines go big, and other airlines fall.
The world of aviation may be different 3 months from now, I'd hate to say it, but airlines like AA, DL, UA, and CO might not make it. I may be over exagerrating a little bit, but I think US Airways is bound to go out, along with a few of the more regional carriers.
The airlines who have the money making routes will be the ones who make it through.
Give me a break, I created this username when I was a kid...
