Choose the correct terminal
Confirm domestic or international status and the exact terminal in the operating airline’s booking message. Allow time for traffic and the route from drop-off to check-in.
T1, T2 and T3 are separate terminals. Domestic assignments between T1 and T3 can change, so recheck before travelling to the airport.
Check-in to boarding
Complete airline document and baggage checks first. Then follow signs for security and, for international flights, exit immigration.
Gate assignments can change. Use the airport screens and airline messages rather than an old screenshot.
Frequently asked questions
