Oh and see I thought the Centurion was free with Amex (anything). I don't have my amex anymore either way. I'm on AC arriving at E (according to wiki) then AA to MEX so it looks like either A,C or D. But that's cool I like checking out airports anyway and I've only ever been to DFW once briefly.
Maybe someone can tell me this, any idea if AA will accept my checked bag like 10 hours prior?
