AirTran Airways, which is a subsidiary of Southwest Airlines, have received approval from the Department of Transportation (DOT) to operate four new international flights to destinations in Mexico.

Flights starting on June 3, 2012 will include one daily round-trip from John Wayne Orange County Airport in California to Cabo San Lucas/San Jose del Cabo in Mexico, as well as one daily round-trip that will travel between the Orange County Airport and Mexico City. In addition, AirTran will offer four new weekly round-trip flights from San Antonio, Texas, to Cancun, Mexico, starting on May 24, 2012.

The flights from the California-based Airport will be supported by new domestic service in the form of one daily round-trip flight from San Francisco to Orange County and another daily round-trip flight from Las Vegas to Orange County, as AirTran does not presently offer flights out of this location.

“With the DOT’s approval, we are excited to now make these destinations available for sale to both AirTran and Southwest’s customers,” said Bob Jordan, who is the executive vice president and chief commercial offer of Southwest Airlines, as well as the president of AirTran Airways. “The new service is another direct benefit of Southwest’s acquisition of AirTran as we take low fares farther by expanding our route maps to more places customers want to go.”

The low, one-way fares (excluding taxes and fees) include a route from San Antonio and Cancun real estate for $119, a route from San Antonio to Mexico City for $119, a route from Orange County to Cabo San Lucas/San Jose del Cabo for $119, and a route from Orange County and Mexico City for $109. Customers must book the flight by December 19^th to take advantage of these low introductory rates and travel between San Antonio and Mexico must take place between May 24^th and June 26^th of 2012, while travel between Orange County and Mexico must take place between June 3^rd and June 24^th of 2012.
