Whats wrong with living in DFW? It's cheap too! But yes, AUS and SAT would be pretty easy commutes. AA has all mainline flights running quite often. Although I believe they are sometimes full, but since they run pretty often, you wouldn't have too much problem getting a jumpseat. I guess if you really needed to get to work, you can take SWA to Love Field, but it'd be an expensive cab ride to DFW. My commute is 3 hours and would love to have a 30 minute commute.
Ok I just read the post above, and I would listen to him, someone who actually does the commute...
