New Direct Flights to St. Thomas in 2026: Airlines, Routes & Deals

New Direct Flights to St. Thomas (STT) in 2026

Cyril E. King Airport (STT) is having its biggest route expansion in a decade. Southwest Airlines launched STT service in 2026 — a game-changer for budget travelers — and multiple carriers are backfilling the routes left behind by Spirit Airlines' shutdown. If you have been dreading connections through San Juan or Miami, 2026 is your year.

Spirit Airlines Is Gone — And That's Actually Good News

After Spirit's second Chapter 11 filing and its wind-down in early 2026, the airline stopped flying to STT entirely. The upside: those slots and that demand did not disappear. Southwest, JetBlue, Frontier, and United all moved in fast, adding capacity on the exact routes Spirit abandoned (Fort Lauderdale, Orlando, Detroit). Fares on those corridors have actually held steady or dropped as competition intensified.

New Nonstop Routes Added in 2026

Why Southwest Matters

Southwest is the first true low-cost carrier to fly STT with two free checked bags, no change fees, and Rapid Rewards points that never expire. For a family of four flying from the East Coast, that alone saves $200+ vs. legacy carriers. Expect BWI and FLL fares to settle in the $220–$320 round-trip range once introductory pricing normalizes.

Airport Reality Check

STT is small and gets clogged around ferry-connection times. Arrival tips:

• Cell service is spotty in baggage claim — cache directions before landing
• Taxi rates are fixed by zone — see the posted board
• Uber/Lyft do not operate — it is taxis or pre-arranged transfers

Connecting to St. John

Once you land STT, you have two ferry options and a barge for cars. Full breakdown in our Red Hook to Cruz Bay ferry guide.
