Online/Mobile check-in
Check in on your computer or mobile device from 48 hours to 1.5 hours before your flight departs. You can also print your boarding pass or download it to your mobile device before going to the airport, if you’re departing from selected cities.
At the airport, proceed directly to the Immigration counter if you don’t have bags to check in and if you don’t require travel document/visa/credit card verification at the check-in counter.
