Cape Air operates the most frequency on STT-SJU, running Cessna 402 and Tecnam P2012 aircraft several times daily. Seaborne Airlines (now operating as Silver Airways in some markets) has also served this route. American Eagle CRJ regional jets historically linked the pair, though scheduling varies by season. The 70-mile hop takes 30 to 35 minutes in the air. Check current schedules, as carrier operations on short Caribbean hops shift frequently.
Cape Air's Cessna 402 holds 9 passengers and carries 100–150 lbs of total cargo weight. Checked bag allowances on small turboprop equipment typically limit bags to 40 lbs per piece and 50 lbs total per passenger. Carry-on bags must fit under the seat; there is no overhead bin on a Cessna 402. Oversized or heavy luggage is better sent by ferry or cargo. Bring your smallest bag and ship larger items ahead if you're relocating.
No direct public ferry operates from St. Thomas to San Juan. The AV Ferries service connects St. Thomas (Red Hook or Charlotte Amalie) to Vieques and Culebra, which are off the east coast of Puerto Rico, not San Juan. Reaching San Juan from St. Thomas without flying requires a ferry to Culebra or Vieques followed by a short flight or a Puerto Rico mainland ferry to Ceiba, then ground transport. Flying STT-SJU is the practical option for most people.
St. Thomas to San Juan: Short-Hop Caribbean Air Link
STT-SJU covers 70 miles between the US Virgin Islands and Puerto Rico's capital in 30 to 35 minutes. Cape Air dominates the route with small turboprop equipment (Cessna 402 and Tecnam P2012), running multiple daily departures. When American Eagle or Silver Airways operate regional jets on the route, block time remains under 45 minutes including taxi. The corridor carries a mix of US residents moving between USVI and Puerto Rico for work, commerce, and family visits, as well as visitors using SJU as a gateway before connecting to the Virgin Islands. Both STT and SJU operate under US domestic rules: no customs or immigration for US citizens, though agriculture screening applies at some Caribbean-specific checkpoints.
Operational Notes for Small Aircraft Routes
STT's Cyril E. King Airport sits on a short runway constrained by terrain to the east and the Caribbean to the west. Crosswind conditions on the single runway regularly affect departure timing. Turboprop operations are more susceptible to wind shear and convective delays than jet aircraft on the same segment. Afternoon cumulus development over the islands June through October adds turbulence on short hops; morning departures are smoother. SJU's Luis Muñoz Marín International is the Caribbean's largest airport and handles connections to the US mainland from American, United, Delta, JetBlue, Southwest, and Spirit.
