Southwest Airlines said it will close its operations in three cities starting next summer.
The Dallas-based carrier said it will no longer serve Branson, Jackson-Evers and Key West airports as of June 7. The carrier had added Branson and Key West when it purchased AirTran Airways in 2011.
"Unfortunately, the level of local demand no longer allows Southwest to profitably serve these markets," said Southwest chief commercial officer Bob Jordan.
Employees at those locations will be able to apply for jobs elsewhere in Southwest's network, the company said.
