Know before you go — STT
Airport terminal opens at 6:00am — you can't get inside earlier.
STT has only 2 TSA lanes — peak lines can exceed 2 hours.
Check-in desks open ~3 hours before departure, not earlier.
TSA PreCheck and Global Entry are both available at STT.
US Customs at STT: the USVI is OUTSIDE the US customs zone, so every traveler heading back to the mainland has to clear US Customs & Border Protection before boarding.
Mobile Passport Control (MPC): use the free app to complete your U.S. Customs declaration before you reach the airport — it can get you through CBP inspection faster.
Saturday mornings remain the busiest time of the week, especially Dec–Apr.
Inter-island prop flights (9K, WB, Tradewind) use a separate check-in area and don't share the main TSA queue.
How the crowd forecast works
Departure crowds are modeled from each flight's seat count × a typical load factor, spread across a multi-hour check-in/security curve that peaks about 2 hours before departure.
Crowd estimates are modeled from published flight schedules × typical load factors. Actual TSA wait times vary. Always verify your airline's check-in window.
