There are lots of crashpads, and most of them are ASA pilots and FAs.
Most tend to be on the north side of the airport in College Park, Hapeville, and East Point. This isn't the best area to be in.
There are also quite a few in Newnan, Griffin, Peachtree, and Morrow, but it's about 20 minutes to the airport and you'd need wheels.
Next time you're here for a while, visit the ASA crew lounge and check out the bulletin board. You may want to check the Airtran boards too.
