How long before flight Heathrow Terminal 3?

Check-in closes 60 minutes before long-haul flights depart and 45 minutes before short-haul flights depart. Pass through security at least 35 minutes before your flight departs. Be at the boarding gate at least 20 minutes before your flight departs.



For departures from Heathrow Terminal 3, which handles a large volume of international long-haul flights (including airlines like Virgin Atlantic, Emirates, and Delta), the general rule in 2026 is to arrive 3 hours before your flight. If you are flying on a domestic or short-haul European route, 2 hours is usually sufficient. Terminal 3 is one of the busiest terminals at Heathrow, and the walk from the check-in area to the furthest gates can take up to 20 minutes on its own. Furthermore, security queues can be a "wildcard"; even with the rollout of modern CT scanners that allow you to keep liquids in your bag, high passenger volumes during morning and evening "bank" hours can lead to significant waits. Arriving 3 hours early gives you a comfortable buffer for baggage drop-off (which often has its own queue) and allows you to enjoy the terminal's famous "Airside" amenities, such as the No1 Lounge or the extensive duty-free shopping. If you are traveling during peak holiday periods or summer weekends, adding an extra 30 minutes to your plan is a wise move to manage the risk of transport delays to the airport.
