Best Times to Go Through TSA Security

A data-driven guide to avoiding long TSA security lines at US airports. Plan your arrival for the shortest wait times.

Best Hours of the Day

Early Morning (Before 6 AM) — Shortest Waits

Airlines start their first wave of departures around 6 AM. Arriving before this rush means you'll encounter minimal lines, though some checkpoints may not yet be open.

Mid-Morning (9-11 AM) — Good Window

The early morning rush has cleared, and the midday wave hasn't started. This is often the sweet spot at major airports.

Afternoon (3-6 PM) — Avoid If Possible

Afternoon departures create some of the longest wait times, especially at business-travel hubs. If you must fly during this window, arrive at least 2.5 hours early.

Late Evening (After 8 PM) — Short Waits

Most departures have wrapped up by this time. Wait times drop significantly, though some checkpoints close for the night.

Consider flying on the actual holiday (Thanksgiving Day, Christmas Day) — airports are often quieter
