one thing nice about DFW Airport is that you can usually get through security pretty quickly, CU should be able to leave go visit with them at that hotel or wherever and then get back in in a relatively quick fashion. The only problem is is that if you're on American they board the airplane 30 minutes early, and if you get off the plane and have a two-hour layover you're really only gotta be left with about 60 to 75 minutes.
