Airlines sponsoring college sports

Well, I went to a University of Michigan basketball game tonight, and to my surprise, a lot of stuff was sponsored by NWA this season.

One of the things sponsored was at half time, a shooting contest (you know, have to score a layup, free throw, 3 pointer etc.) for WorldPerks miles and a free r/t in the US... what bugged me was the contestants wore NWA 787 shirts!!! GRR! I WANT ONE!!

But anyway, what other airlines sponsor college teams and what are the teams???
