AirTran is interviewing Oct 8th and 9th. I'm pretty sure all those slots are filled. Not sure if any more interviews have been scheduled after that. I know they plan more, I'm just not sure if they have firm dates or have begun calling to fill any interview slots after the ones on the 9th.
There is also a new hire class beginning on Oct 10th, with one more planned for Nov. Those classes are filled with those that had already interviewed and been selected.
At least that's the word today. As always, this is all subject to change on short notice.
