Southwest Airlines opened its summer 2027 schedule on Friday, October 2, 2026, and Nashville International Airport (BNA) gets three new seasonal nonstop routes: Boise, Nassau in the Bahamas and Providenciales in Turks and Caicos. The schedule runs from June 3 through August 2, 2027, and is bookable now at Southwest.com.
Nashville travelers should treat this as a planning window, because a summer trip to the islands can now be booked without a connection. If you are choosing where to fly from, the guide to the closest airport to Nashville explains how BNA compares with the alternatives.
- New from Nashville: Boise, Nassau and Providenciales, all seasonal.
- Returning from Nashville: Bozeman, Montana, and Portland, Oregon.
- Schedule window: June 3 through August 2, 2027.
- Nashville peak: up to 220 daily trips, as many as 20 more than summer 2026.
- Booking: open now at Southwest.com.
The Three New Nashville Routes
Reporting from The Points Guy lists Nashville to Boise, Nashville to Nassau and Nashville to Providenciales among the 11 routes in Southwest’s latest expansion. Nine of the 11 routes are ones Southwest has never flown before.
Both island routes are new for Nashville, and Nassau is one of the Bahamas destinations that Southwest is also adding from Austin in the same schedule. The reports we read did not publish days of the week or exact start dates for the Nashville routes, so confirm those on Southwest.com before you plan around them.
Returning Seasonal Service
Upgraded Points counts five seasonal routes from Nashville in total, three of them new. The other two bring back Bozeman and Portland, Oregon, which Southwest flew from Nashville in 2026 and is restoring for summer 2027.
Seasonal means the flights run only during the summer window. Outside June 3 to August 2, 2027, none of these routes appear on the schedule that is open for booking today.
What 220 Daily Trips Means in Nashville
Southwest says it expects up to 220 trips a day in Nashville on peak days next summer, as many as 20 more departures than in summer 2026. Upgraded Points ties the growth to the crew base Southwest opened in Nashville in 2024.
More departures usually mean more time-of-day choices on routes Nashville already has. For a traveler, that matters most on peak summer weekends, when the earliest and latest flights tend to sell first.
Lounges Are Coming Too
Southwest is building airport lounges in Nashville and Austin, two of the four it plans to open in 2027. Construction is underway, and the sources we read gave no opening date for either one.
Nothing in the schedule announcement links the lounges to specific flights, so do not assume lounge access when you price a trip.
Planning a Trip to Nassau or Providenciales
Both island routes are international, so a valid passport is the safe assumption for U.S. citizens, and other travelers should check the entry rules for the Bahamas and for Turks and Caicos. Rules can change, so confirm them with each government before you book.
If you want to pair the flight with a stay, the guide to where to stay in Nassau covers the main areas to consider. Because these are seasonal routes with limited days, flexible dates usually help you find the best fit.
The Bigger Southwest Picture for Summer 2027
Southwest says it has scheduled 4,498 trips on peak days for summer 2027, the most it has ever run in a single summer, according to Upgraded Points. The announcement also covers Austin and San Diego, and Nashville is one of the three markets the airline is leaning on hardest.
For Nashville travelers, the practical point is simple: the three new routes are on sale now, the schedule window is fixed, and the missing detail is the day-by-day pattern. Check back on Southwest.com as booking opens up for your dates.
How This Fits Earlier Nashville Announcements
Southwest announced a separate batch of Nashville nonstops in July 2026, starting in March 2027, which our earlier report on the St. Thomas nonstop covers. The summer routes here are a different set, and they start later in the year.
Travelers comparing Southwest across cities can also read how the same schedule reshapes Austin planning for Nassau nonstops. Southwest’s own newsroom at swamedia.com carries the company’s announcements.
| If you… | What to do |
|---|---|
| Want a Bahamas or Turks and Caicos trip from Nashville | Check Southwest.com for Nassau and Providenciales dates between June 3 and August 2, 2027. |
| Live in the Mountain West or Idaho | Look at the new Boise link as a way to reach Nashville without a connection. |
| Need exact days of the week | Wait for the published schedule detail; the reports we read did not list days for these routes. |
| Plan a July 4 trip | Hold off, because Southwest will publish a reduced July 4 schedule later. |
June 3, 2027 is the start of the schedule window. Early June is the first date any of these routes can operate, so build summer plans from that date forward.
August 2, 2027 is the end of the schedule window. Trips that return after that date are not yet bookable on Southwest.
The July 4 schedule is still to come. Southwest says a reduced schedule will be published later, so holiday plans may change.
