Looking for some advice - I have 148 Airtran credits but have not converted to Southwest (yet). I would like to fly 4 of us Atlanta-Austin Labor Day weekend on credits. Neither the Airtran nor Southwest website will show me those dates yet. Is there a way to book these dates by phone, or do I have to wait until the scheduling window opens up? Am I better off trying for AirTran or just converting to Southwest points and going through them? We'll be in coach so the biz class on Airtran is not a factor.

Any advice would be greatly appreciated.
