Just wanted to post this for others, just booked the second ticket at the cheap price, was only 1 cheap seat available 2 days ago when I booked the first one....... lo and behold another cheap one became available just a few minutes ago and I snagged it.

Might be a way Airtran gets people to buy the next higher priced ticket by only showing 1 seat available at the cheap price........I guess its a marketing way to sell 2 seats at a time figuring people won't wait and purchase the second ticket at the higher price.
