Finding your check-in zone
You'll find your check-in zone listed on the information screens near the departures entrance (the zones themselves are marked by illuminated yellow cubes).
You should have received check-in instructions with your booking. If you can't find them, your airline or travel agent will be able to help.
However, as a general guide you should aim to arrive:
- Long-haul and El Al: three hours before scheduled departure
- European flights: two hours before scheduled departure
- UK and Ireland flights: 90 minutes before scheduled departure.
Even if you have already checked in online you should still allow plenty of time – check the times given by your airline for dropping bags, collecting boarding cards and getting to your gate.
Use online check-in to select seats and print boarding passes before you get to the airport. Then when you arrive, just drop your baggage at the bag-drop kiosk and you're ready.
Some airlines also offer mobile check-in, where boarding cards are sent directly to compatible mobile devices. All you have to do is drop your baggage at the bag-drop kiosk and go straight to security.
To find out if you can use this service, please check with your airline.
Please note that passengers who have checked in on their mobile phones or online still need to arrive in good time for their flight. Please pay close attention to the times given by your airline for dropping bags, collecting boarding cards and arriving at the gate.
Many airlines offer self-service check-in kiosks where you can choose your seat and print your boarding card, then take your baggage to the bag-drop facility. Airline staff will be on hand if you need help.
