International arrivals

| Main | 10 min | 18 min | 193 min | 0.7% |

Source: US Customs and Border Protection · 2024-08-28 to 2026-08-27 · These are CBP passport control waits for arriving international passengers — a different queue from TSA departure screening. CBP publishes them about two days in arrears, so this describes what is normal rather than what is happening now.
What to expect at SAT
How busy the airport is through the day, from scheduled departure volume.
Scheduled departures by hour
The busiest hour is 6 AM, with about 12 departures a day, against roughly 1 at 9 PM. Counterintuitively, that peak is also more punctual than a typical hour here — early banks fly aircraft that have been on the ground overnight rather than ones inheriting the day’s delays.

Weekly and seasonal patterns
By day of week
Tuesday is historically the most reliable day and Sunday the least, a gap of 4.9 percentage points.
