Southwest Airlines has announced that it will start offering nonstop flights between Portland and Orlando early next year. The airline said in a release that the “seasonal route” will be on Saturdays starting March 11. The Portland International Jetport previously had a nonstop flight to Orlando on AirTran. That flight ended in April 2012. AirTran merged with Southwest in May 2011. Airport Director Paul Bradbury tells The Portland Press Herald, that Orlando is the third-most-popular destination for passengers flying out of Portland, after the Washington, D.C., area and the New York City area. The jetport has had a slight increase in passenger traffic.
