How early should I arrive before boarding?

Check-In Times at U.S. Airports For most airports, you must be checked in at least 30 minutes before your scheduled departure time (airports requiring additional time are listed below, Go to footer note). Additionally, you're required to be at the gate and ready to board 15 minutes before scheduled departure.



For a stress-free experience in 2026, the gold standard is to arrive at the airport 3 hours before international flights and 2 hours before domestic flights. This "arrival" means being inside the terminal, not just pulling into the parking lot. While biometric gates and "Express Security" lanes have become more common in 2026, staffing shortages and technical glitches can still cause unpredictable queues. If you have bags to check, be mindful that many airlines close their "Bag Drop" exactly 60 minutes before departure; missing this cutoff means your luggage won't make the flight. If you have no bags and have already checked in via an app, you can theoretically arrive 90 minutes early, but you are at the mercy of the security line. Remember: boarding usually begins 45 minutes before takeoff and the gate closes 15–20 minutes before the plane pushes back.
