Southwest Airlines is doubling down on some of its top strongholds, and planning a blockbuster slate of new routes for early next year.
The Dallas-based carrier on Thursday announced it's adding more than a dozen new routes with a big focus at several airports where it's made a big push in recent years, including: Austin, Texas; Orlando, Nashville and San Diego.
Nashville International Airport (BNA) and Las Vegas' Harry Reid International Airport (BNA) were the biggest winners, with four new routes apiece.
