AirTran Airways A+ Rewards - Cost to use A+ International Reward

I have only used the Southwest Rapid Rewards, so sorry for a newbie question.

What is usually the cost each way to use a A+ reward internationally. With Southwest it only cost $5 each way to use a reward. Looking to do MDW to CUN or MDW to MBJ. Is there additional cost to pick a seat?

Thanks in advance
Chris

Just like WN the security fee of up to $5 has to be paid.

Yes the usual seat fees of $6-$20 apply... though if you're A List with RR you can get Elite status on A+ and your seat fee and bag fee (2 bags) would be waived. Though any travelling companion not Elite would still have to pay them.

For a party of two unless you really want say exit rows prompt online checkin at t-24 normally has decent availability for free.
