Southwest Airlines is now coordinating schedule releases with AirTran, which the company acquired in May.
"These new flights are a result of better utilization of our aircraft and begin to deliver on what we've characterized as 'more flights, more options' as the two carriers become a larger, more nimble Southwest Airlines," spokesperson Brad Hawkins said in an email Sunday.
Southwest also announced that AirTran is filing with the Department of Transportation for the authority to fly some new, international service to Mexico, including nonstop flights from San Antonio to Mexico City and Cancun and from Orange City, California to Mexico City and Los Cabos.
Tickets sales for the new international services are pending government approval.
