Before departure
Terminals, check-in counters, and boarding gates vary by airline and date. Follow your flight booking and the airport’s departure displays on the day.
Transport and timing
Airport trains and buses have their own first and last services, while airlines set separate check-in deadlines. Plan your airport arrival to allow for security and the walk to your gate.
From check-in to your gate
Check the terminal on your booking, then complete airline check-in and bag drop. The public area before departure formalities is separate from the airside shopping area beyond security and passport control. Lounge access comes after those formalities.
- Check your terminal, counter and gate on the flight display.
- Separate checked baggage from cabin bags and complete airline check-in.
- Pass security and passport control, then locate your gate.
- Finish your meal or lounge visit in time for the boarding time on your boarding pass.
Flights departing from the concourse
Allow for the shuttle train if your flight leaves from the concourse. The airport warns that passengers cannot return after travelling from Terminal 1 to the concourse: finish any Terminal 1 lounge or shopping visit before boarding that train.
Gates can change, so recheck the displays and airline messages. A lounge allowance is not a measure of how much time remains before boarding.
Rail, buses and help desks
Follow signs to the transportation centre basement for the airport railway and to the terminal first floor for airport buses. Make sure you get off at Terminal 1 rather than Terminal 2. For buses, check the destination, boarding bay and final departure.
Public-area help desks include Terminal 1 level 3 near central entrance 8 and level 1 near entrances 5 and 10. Their locations are listed in the airport facility directory.
