Airport Deadlines by Flight Type

Every departure has the same five deadlines; only the numbers change between domestic and international.

The first number is arrival guidance: three hours before an international departure, two hours before a domestic one. This is the outer envelope inside which every other deadline must fit.

Check-in and bag-drop desks close 45–60 minutes before an international pushback and 30–45 minutes before a domestic one; the exact minute is set by each airline. This is the earliest hard wall and the one that strands the most luggage.

Boarding starts 30–45 minutes before departure for both flight types, and the gate closes 10–15 minutes before pushback. The boarding time printed on the pass is an invitation, not a deadline — the deadline is gate close.

Connections carry their own minimums: roughly 45–90 minutes for domestic-to-domestic and 60–120 minutes for international itineraries, depending on the airport. Anything shorter sits below the airport's own minimum connection time.

International departures cost more time because more is checked: passport validity — often six months beyond the entry date — is verified at the desk before a bag tag is printed. That document check is why the international column runs 15–30 minutes tighter at almost every stage.

Use this table together with the queue estimates on How Long Security Screening Takes and the worked example in Departure Countdown: T-3 Hours to T-0; the three pages are one procedure split into reference, queue and schedule.
