Southwest Airlines has unveiled plans to begin seasonal flights from Nashville International Airport to Nassau, Providenciales, and Boise starting in June 2027. The airline is also resuming seasonal service to Bozeman and Portland as it continues to grow its hub operations.

Why it matters

The expansion reflects the airline’s ongoing effort to meet increasing demand from tourism and business travelers in the region. This growth builds upon recent infrastructure investments and a steady rise in flight departures at the airport.

Southwest operates 43 gates at Nashville International Airport, supported by a $539 million investment in hub renovations over the last decade. The facility is currently constructing a 30,200 square foot travel lounge.
