I don't commute, and at this point in my careed WILL NOT COMMUTE! Any commute dramatically lowers your QOL.
I have flown with 2 guys that commute from AUS. One was a very senior A320 Captain that retired early...that should tell you someting. The other guy is the Chief Pilot for the 787 and he gets positive space both ways every week.
The problem with AUS in the past is it has been weight restricted due to the DC-9, and I don't believe we have more than a couple mainline flights in and out of there. I believe Compass/Mesaba are operating many of the flights now.
I know AUS is a great place to live, but you will pay the price. Best advice is move to a base.
