AirTran Airways A+ Rewards - Consecutive flight #s ATL - CHS: Same plane?

I'm looking at doing a couple of roundtrips to hit Elite status and the likeliest candidate is the ATl- CHS route. I will most likely be doing this on a weekend and would like to keep the turnaround time as short as possible. There are some flight pairs on this route with consecutive flight numbers (e.g. 880,881) that involve a departure out of CHS approximately 30 minutes after the most recent ATL flight's arrival. From what I can gather of the information on CHS's website, it looks like all Airtran flights go to gate A1.

Can anyone confirm whether or not this is correct? If so, would it be safe to assume I'd be on the same plane on both flights, given that there is only one gate for Airtran to use? In that case, I wouldn't have to worry about the 30 minute connection time because in the event of a delay, I'd already be on the delayed aircraft headed to CHS ...

Thanks for any insight you can provide!

I'm not much of an Airtran flier, but since Airtran only flies to ATL from CHS, what goes into CHS from ATL has to come out of CHS to ATL. It's a pretty safe bet you'd be on the same plane in and out of CHS.

I guess the only way things could get messy is if things are running really late, Airtran cancels a CHS-ATL flight and sends the plane from an earlier ATL-CHS flight as the next scheduled flight, which would otherwise be your return. It's unlikely, but possible, I suppose. Like I said, I don't fly Airtran enough to know. But you'd probably be able to tell this is going to happen while on the ground in ATL and declare a trip in vain or get the agents to put you on a later return flight. And flights can always get canceled due to weather, but if your CHS-ATL flight is canceled, Airtran should put you on another flight anyway.

Thank you, longtime lurker! I appreciate your help.
