I think I may have ended up accidentally booking myself on the last AirTran revenue flight on the 737. Flight 1043 (SWA 6043) ATL-LAS on 11/30. It doesn't go back to Atlanta afterwards, so my guess is its a ferry flight to the shop for a paint job and to get reconfigured. Sure will miss AirTran.

If anyone finds a later one, post it up!
