SJU–STT Quick Facts
Frequently Asked Questions
San Juan to St. Thomas: The Essential Inter-Island US Territory Link
SJU–STT is one of the shortest commercial air routes in the US territories, covering 73 miles between Luis Muñoz Marín International in Puerto Rico and Cyril E. King Airport on St. Thomas in the US Virgin Islands. Cape Air operates the route on small turboprop aircraft, typically Cessna 402s or Caravans with 9-seat capacity. InterCaribbean and regional operators provide competing service. Both airports fall within the US domestic system, meaning no customs clearance is required for US citizens or residents traveling between them. The flight serves residents of the USVI who need Puerto Rico's larger airport for connections, medical travel, and government business, as well as tourists distributing between the two destinations.
Aircraft Type, Weight Limits, and Connecting Context
The SJU–STT route operates exclusively on small turboprop and piston aircraft due to the short distance and relatively low passenger volumes. STT's runway and infrastructure support regional jet operations, and American Eagle has served the route intermittently, but the core market is sustained by Cape Air's high-frequency small-plane schedule. Passengers connecting from the US mainland arrive at SJU on American, JetBlue, Delta, or United and transfer to the interisland carriers in a separate terminal area. Baggage restrictions on the small aircraft are a genuine operational constraint, particularly for dive tourism to the USVI's waters.
