Which terminal this flight departs from
Departs from Terminal 2, the Queen’s Terminal, in the Central Terminal Area and the Star Alliance base. Check-in and bag drop are in the main T2A building; after security some gates sit in the airside T2B satellite, a walk away, so leave time. There are lounges in Terminal 2 once you are through, and you can check the security queue before you travel. The shared Heathrow Terminals 2 and 3 station brings you in on the Elizabeth Line, the Piccadilly Line and Heathrow Express, a short covered walk from the departures level. See the Terminal 2 guide.
Check-in, bag drop and security
Online check-in usually opens 24 hours before departure. Bag drop desks generally open about three hours before a long-haul flight and close 60 minutes before departure, though the exact cutoff is set by the airline, so confirm yours. Everyone leaving goes through the same central security search: liquids follow the limits shown at the terminal on the day, and the hand-baggage rules are on the luggage page. Fast Track security is sold at some terminals if you would rather skip the main queue. For a long-haul departure, arriving about three hours before takeoff leaves room for bag drop, security and the walk to a satellite gate.
A morning departure and the queues
Leaves in one of the busiest security windows of the day, the mid-morning long-haul bank. Allow the full recommended arrival time and check the queue before you travel. Every way in is running: the Elizabeth Line, Piccadilly Line, Heathrow Express and the coaches.
Seeing someone off on SQ317
You can only go through to the departure lounge with a boarding pass, so there is no gate farewell at Heathrow. Say your goodbyes landside in the Terminal 2 departures hall, before the passenger goes through security. If you have driven, the cheapest place to wait is Terminal 2 short-stay rather than the forecourt, where the £7 drop-off charge applies.
Getting to and from Heathrow
Getting to Heathrow for SQ317: if someone is dropping you off, the forecourt carries a £7 charge, or they can use the Terminal 2 Park & Ride free 29-minute window instead. For public transport into the terminal, compare the Heathrow Express, the Elizabeth Line, the Piccadilly Line, coaches, black cabs and private transfers.
