The last time I flew AirTran, a couple of months ago, their FF program was set to terminate at the end of this year, as I recall. At that time, no one had any word on whether or not it would be continued, replaced by a different program, or what. Like I said, though, this was a while ago, and I don't know what the current status is.

It's an innovative program and if they elect to continue it, I'll definitely book more flights with them.
