I fly out of Hartford, CT. In the last few months that I've been traveling, US Air has never had a schedule + price that would make me choose them over NW or AA. Of course when I'm going south, Delta makes sense for me, and I know I'm new to the world of flying frequently, but I've never had an unpleasant experience on Delta. However, after reading some topics here I'm beginning to think that their FF program isn't worth striving to achieve a higher level in (i'm currently silver).

when i'm not traveling for my job, i mostly travel to wisconsin to visit my family (wish midwest express would expand their market), mississippi to visit my friends, the Caribbean and (hopefully) Europe when I take my vacations. Because of AA's coverage to the Caribbean, I was leaning toward them.

thanks for all the help so far, y'all!
