Cape Air, Seaborne Airlines (now part of InterCaribbean), and InterCaribbean Airways operate SJU–STT nonstop on turboprop aircraft. American Eagle has operated the route with regional jets. Cape Air uses Cessna 402 and Grand Caravan aircraft, typically seating 9 passengers. Flight time is 25–30 minutes. Departures run 4–8 times daily depending on the carrier and season. Both airports are US domestic for customs purposes, as Puerto Rico and the US Virgin Islands are US territories.
No direct ferry service operates between San Juan and St. Thomas. The water route requires a stop in Culebra or via a private charter. The Vieques/Culebra ferry from Ceiba, Puerto Rico to St. Thomas does not exist as a scheduled commercial service. Some high-speed private charter boats operate the crossing, but no public ferry links SJU and STT. The seaplane service that historically connected the islands (Seaborne) now focuses on interisland flights. For most travelers, the 25-minute flight is the only practical transport option.
Cape Air's 9-seat aircraft have a strict 15 lb carry-on limit and a 50 lb checked bag limit per passenger. Total baggage weight (carry-on plus checked) is often capped at 40 lb on some Cape Air legs due to weight-and-balance restrictions. Passengers with dive gear, large suitcases, or sports equipment should contact the carrier before booking. Overweight bags may need to travel on a later flight if the aircraft is at maximum payload. Pack light or ship luggage separately for extended stays.
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.
