At least at ATL, Airtran has pretty much all of C terminal. Mind you there are 30ish i think gates split 15 on each side so it's not THAT far to walk from train to one end of the terminal.
The choice of terminal is irrelevant because it just means a shorter or longer train ride from ticketing/baggage claim. Unless you're connecting with other airlines, you usually don't have much to worry about.
