ATLANTA -- AirTran moved closer Monday to becoming part of Southwest Airlines.
The latest move in bringing the two airlines together involves combining the frequent flyer programs.
If you fly AirTran or Southwest and are enrolled in both frequent flyer programs, you can now use your frequent flyer credits on either airline.
The good news is whatever number of points you needed to get a free trip on AirTran or Southwest stays the same, giving passengers the option of going to 97 destinations.
There is a catch.
The credits expire one year after you get them.
On many airlines, like Delta, frequent flyer credits never expire.
As you transfer points, be sure to keep in mind that AirTran continues to charge passengers for flight changes and checked bags.
Southwest does not, but they say they will not change AirTran policies until the two airlines are fully integrated.
