You may be able to check-in on your airline's website using the ticket number and airline reference found on your itinerary.
To see how many days in advance you can check-in online, please visit your airline’s website. All airlines have different dates so it is best to check directly with them as these can change.
Terminal information can also be found on your itinerary.
If you have purchased an STA Travel fare, and your ticket number begins with 000-09, you may not be able to check in or manage your booking on the airline's website.
If you are unable to log in on the airline's website, you will be required to check in at the airport in the normal way.
