Got a response. Here it is:
*
Thank you for contacting AirTran Airways via email.* You may bring a stroller to the gate for ease of travel through the airport.* The stroller may be gate*checked just before boarding the plane,*and will be returned to the aircraft jet way upon arrival at your destination.**Car seats and strollers may be checked at the ticket counter free of charge; however, any other items would be subject to excess luggage fees (i.e. portable crib high chair...etc.).*
*
In regards to your inquiry, you may check the stroller in a box for no fee.* However, if there are any additional items placed in the box with the stroller there will be a fee based on the size and weight of the box in addition to a baggage charge.
*
Should you need any further assistance, please do not hesitate to contact us again.* We thank you for including AirTran Airways in your travel plans and we wish you a very pleasant flight.

Sincerely,
