How early should you leave for a flight?

A good rule of thumb is to get to the airport at least two hours before your flight is scheduled to depart for short-haul flights. If you have any bags to put in the hold and/or you need to check-in in person (ie. you haven't been able to do so online), you may want to leave a little longer.



For travel in 2026, the gold standard remains arriving at the airport three hours before an international flight and two hours before a domestic one. While technology has introduced "High-Fidelity" biometrics and digital bag drops, the sheer volume of global travel has increased security wait times and terminal congestion. Arriving early is essential if you have bags to check, as most long-haul counters close exactly 60 minutes before departure. If you are traveling during peak seasons or from major hubs like Heathrow, JFK, or Dubai, adding an extra 30–60 minutes is a wise safety margin. Premium travelers with "Fast Track" access or "Twilight Bag Drop" privileges may be able to arrive closer to the 90-minute mark, but unpredictable security queues make the 3-hour rule the only way to ensure a stress-free start to your journey, especially given the strict "boarding gate close" times (usually 20 minutes before takeoff).
