St. Thomas airport wait times right now, tonight, and tomorrow morning. Live TSA and U.S. Customs crowd forecast for Cyril E. King Airport (STT) — see the calmest check-in windows and time your arrival.
STT airport security combines TSA screening and U.S. Customs pre-clearance in one line — travelers leaving the US Virgin Islands for the mainland clear customs at STT before TSA, which is why St. Thomas TSA wait times can run longer than a typical domestic airport. The forecast above breaks down the STT airport security wait times by 30-minute window so you can see when the line is Low (under 15 min), Moderate, High, or Severe (70+ min).
This St. Thomas airport wait-times forecast models TSA and U.S. Customs checkpoint waits at Cyril E. King Airport (STT) using scheduled departure seat counts and a time-distributed passenger arrival curve. Each departure's passengers are spread across a 4-hour pre-departure window, with the peak about 2 hours before scheduled departure. Severity ratings (Low, Moderate, High, Severe) are based on 30-minute passenger volume thresholds calibrated for STT.
Because the US Virgin Islands sit outside the US Customs zone, travelers leaving St. Thomas for the mainland clear U.S. Customs before TSA — so STT wait times today can run longer than a typical domestic airport on busy cruise-and-flight mornings. Check the forecast above before you leave for the airport.
