I do the commute. . .It's not the best. . .not the worst. Usually five direct flights a day to JFK on us, Delta and AA. We are the least reliable. Commuting on the day of reserve or a trip is not a good idea. We usually have a late flight that leaves JFK around 2100 so it's usually okay to commute home on the last day. If I had to choose it over again, AUS would not have been my first choice as a commute city.
