AirTran Airways' service from John Wayne Airport to Cabo San Lucas will switch carriers in August.

AirTran parent Southwest Airlines will take over the daily, non-stop service previously offered from JWA through AirTran beginning Aug. 10.

It's offering an introductory, one-way fare of $143.

The switch to Southwest is part of a planned integration of AirTran’s operations under the parent company’s banner.
