Seaborne Airlines is a regional carrier based in the United States Virgin Islands, specializing in short-haul flights throughout the Caribbean. The airline operates scheduled passenger services connecting key islands including St. Croix, St. Thomas, Puerto Rico, and other regional destinations, serving both locals and tourists.
Founded in 1989, Seaborne built its reputation on serving routes that larger carriers often overlook, providing essential air connectivity to island communities. The airline has operated seaplane and turboprop services, reflecting the unique geography of its operating environment.
Seaborne Airlines has undergone ownership and operational changes over the years, at various times operating as a codeshare or partner carrier with larger airlines such as JetBlue. The carrier plays a vital role in inter-island mobility across the U.S. Virgin Islands and the broader eastern Caribbean region.
