aw, i feel kind of sorry for the guy, this whole situation must be so degrading and embarrassing (yes, he probably did it to himself, but still). i don't blame the airline for not letting him fly one bit, though. if he really needs constant oxygen and medical supervision and is carried in a wheelchair they should've told the airline beforehand. i'm sure they would've told him there's no way he can fly like this on a commercial flight. you can't be that careless/ignorant and then cry when things don't go your way.
