Southwest is adding a nonstop between Nashville International (BNA) and Cyril E. King Airport (STT) in St. Thomas. Service starts March 13, 2027, and it runs once a week on Saturdays through the season.

Southwest only arrived in the U.S. Virgin Islands in February 2026, and it is already flying to St. Thomas from Orlando and Baltimore/Washington. Nashville becomes the third U.S. gateway, and it hands a big slice of the Southeast a route that has never existed before.

St. Thomas is not the only Caribbean addition out of Nashville, either. Southwest is launching Saturday-only March service to Aruba, Liberia in Costa Rica, and Montego Bay as well, which turns one city into a genuine winter-sun hub.

Jennifer Matarangas-King, commissioner of the U.S. Virgin Islands Department of Tourism, said the new service “gives travelers across Nashville and the broader Southeast a more convenient way to experience the U.S. Virgin Islands while opening the door to a market with significant growth potential.”

One flight a week isn’t much capacity. A Saturday-only seasonal route fills early, and the spring break weeks will go first.

Delta will fly Austin-Bergstrom (AUS) to Paris-Charles de Gaulle (CDG) starting March 27, 2027. It runs daily through the summer season, and it is the first nonstop ever flown between Austin and Paris.

You’ll fly it on an Airbus A330-900neo with four cabins: Delta One with lie-flat seats and privacy doors, Delta Premium Select, Delta Comfort, and Delta Main. Paris also works as a connecting point. Through Delta’s joint venture with Air France-KLM, the route puts nearly 70 destinations across Europe, India, and Africa within one connection of Austin.

Joe Esposito, Delta’s executive vice president and chief commercial officer, framed the route as part of a longer bet on the city: “Austin’s growth continues to create new opportunities for customers, and Delta is proud to grow alongside it.”

Paris is the headline, but it sits inside a much bigger Austin build-out, and that matters if you fly out of AUS regularly. By summer 2027 Delta expects to serve roughly 30 destinations from Austin with more than 70 peak-day departures, plus new daily San Diego service and a second daily San Jose frequency starting April 12, 2027.

Both routes are seasonal, and seasonal routes do not behave like the year-round flying you are used to booking. Four things worth knowing before you plan around either one:

• Your selling window is short. When the season closes the flight does not drop to a lighter schedule, it disappears until the following year.
• Saturday-only service pins your whole itinerary to one departure day, so you’ll build the rest of your trip around that date rather than the other way around.
• Premium cabins and award space on a brand-new long-haul route are usually at their best the week the schedules load, and they thin out fast after that.
• A new nonstop isn’t automatically your cheapest way to go. In the first season it’s often the opposite, and the value sits in the hours you didn’t spend connecting through Atlanta or JFK.

If either of these lines up with a trip you’ve been circling, now’s the moment to say so. I’d much rather hold your dates this month than explain in January why the only Saturday that works for you is already gone.
