SAT Customs & Immigration Wait Times

What these numbers mean

Each row is CBP's most recent published hour for that arrivals facility at San Antonio International Airport. The average is what a typical passenger in that hour spent between reaching the primary-inspection queue and clearing passport control; the max is the longest anyone waited. US-passport and visitor lanes are staffed and reported separately, which is why the columns diverge. In the data above, the longest published wait at SAT was 23 minutes (Main), with 6 booths open in that hour.

If you clear customs at SAT more than once or twice a year, Global Entry is the single biggest lever: members use kiosks or e-gates and bypass the standard queue entirely, so the max-wait column above largely stops applying to them. Mobile Passport Control — CBP's free app, no interview required — gets US citizens and eligible travelers a shorter dedicated lane and is the best zero-cost fallback when the visitor or standard lines run long.

Arrival peaks, not time of day alone, drive these waits: transatlantic banks tend to land in the early-to-mid afternoon and transpacific and Latin America banks in the morning and evening, so several wide-bodies can feed one arrivals hall inside an hour. Booth staffing matters just as much — a modest arrival bank with few booths open can out-wait a heavy bank that is fully staffed, which is why the booths-open column is worth reading alongside the waits.
