Airtran rates

[Mickey's Girl]

I have been watching Airtrans rates for our March trip, and the lowest fares for non-stop are gone. Does anyone know if they ever go back to the lower rates for those times, or if they are gone once are they are forever? I am not sure I am making myself clear, but basically I am trying to decide whether to take the rate offered today, or wait and hope that they will lower the rates again. I thought maybe some folks who fly Airtran regularly might be more knowledgeable on their policies and help me figure this out Thanks!!
