According to AirTran's facebook page, the airline will be unveiling "a special treat" tomorrow morning (6/16/) at 8 ET.

The guesses posted from FB users are all over the board, but I'm guessing it will just be an announcement about some new onboard snack/drink that will be available in flight. Perhaps they'll announce that little debbie cakes will be available or something like that.

Or maybe it's something totally different.
