Southwest Airlines is closing AirTran Airways’ reservations centers in Carrollton and Savannah but keeping a call center in Atlanta, the airline announced Wednesday.

Southwest, which acquired AirTran last year and has been gradually integrating AirTran operations into its own, said it will close the Savannah and Carrollton call centers on July 31, 2013.

The company has 126 employees in Carrollton and 159 in Savannah. Those employees will be offered job in Atlanta or other Southwest call centers.

Southwest will move AirTran’s reservations center from Phoenix Boulevard, where roughly 300 employees work, to AirTran’s Atlanta corporate center in College Park. The Atlanta call center will open in its new location in May 2013, and will eventually handle Southwest calls, according to the airline.
