Southwest Airlines will soon cut more AirTran routes this fall as it transforms AirTran's hub into a Southwest operation.

Southwest is eliminating routes between Atlanta and Memphis, Pensacola and Buffalo this fall.

Meanwhile, the Dallas-based airline is adding flights from Atlanta to Hartford and Oklahoma City. Also as part of the new flight schedule starting Nov. 3: Atlanta-San Juan, Puerto Rico service will be converted from AirTran to Southwest.

Southwest, which bought Orlando-based AirTran and its Atlanta hub in 2011, started its own Atlanta flights last year and has been gradually expanding them as it absorbs AirTran operations and planes. AirTran operates about 140 daily flights from Atlanta, the world's busiest airport, while Southwest has about 30.
