Southwest Airlines Co. intends to grow its network in 2026 initially with new service at Cyril E. King International Airport (STT) on St. Thomas, adding the U.S. Virgin Islands to the carrier’s tropical destinations in the Caribbean. Service is expected to begin in early 2026* and will be available for purchase soon.

St. Thomas is the first of three new destinations for 2026 the carrier expects to announce this summer. It will be the ninth island destination served by Southwest in the Atlantic Basin – joining Aruba, The Bahamas, Cayman Islands, Cuba, Dominican Republic, Jamaica, Puerto Rico, and Turks and Caicos Islands. Southwest also offers international service to Belize, two destinations in Costa Rica, and three destinations in Mexico.

In addition to offering new destinations, Southwest also is set to begin selling assigned and premium seating in the third quarter of this year and plans to operate with its new fare bundles and a reconfigured fleet, including extra legroom seating, in the first quarter of 2026.
