Dallas, Texas - Southwest Airlines Co. filed an application Tuesday with the U.S. Department of Transportation to provide daily flights between Denver International Airport and Lic. Gustavo Diaz Ordaz International Airport in Puerto Vallarta, Mexico.

Dallas-based Southwest said in a release that the flights would begin in November, pending approvals from government agencies.

"Our new daily flight from the Rockies to the Mexican Pacific coastline will give our Colorado customers as well as connecting passengers quick access to another international destination," Steven Swan, Southwest Airlines director of international planning, said. "We expect strong demand from both leisure and business Customers for this route to the growing region that straddles both Jalisco and Nayarit."

The airline said its service to Puerto Vallarta will begin on June 7, 2015 with a daily flight from John Wayne Airport Orange County. Puerto Vallarta is the airline's fourth destination in Mexico.

Southwest said the flight times and fares for the Denver - Puerto Vallarta route will be announced in the coming weeks.
