I've never booked Airtran before, but am looking at it for a February trip. This seems like a stupid question, but how do you know when they've opened up?
The site lets me search for the last half of Feb, but then tells me that flights aren't available because either the flights are full or because they haven't yet opened. But I don't know which is true in my case. I know that they do fill up pretty quickly once they are opened.
