Southwest Airlines has announced plans to expand its Caribbean service with new nonstop flights to St. Maarten beginning in April 2026. The airline will offer daily flights from Orlando International Airport to Princess Juliana International Airport, starting April 7, 2026. Two days later, weekend service from Baltimore/Washington International Thurgood Marshall Airport will also begin during peak travel weeks.
This marks Southwest's first international route addition since it began flying to Cozumel earlier this decade. The announcement follows last month's news that the carrier would add St. Thomas as a destination and earlier this summer's introduction of flights to McGhee Tyson Airport near Knoxville, Tennessee.
"St. Maarten is Southwest's first international destination since 2021 — and SXM will be just its third new airport during that period. Earlier this summer, the Dallas-based carrier announced new flights to St. Thomas' Cyril E. King International Airport (STT) and Tennessee's McGhee Tyson Airport (TYS) outside of Knoxville."
