Check alternate departure airports other than your NYC staples (LGA, EWR, and JFK). I see numerous carriers offering $198 roundtrips from Long Island (ISP) to Austin in March 2004 thanks to the Southwest effect. The same goes for arrival aiports. SAT, for example, is only an hour and fifteen minute drive from Austin.
