In order to use online check-in, you must know the surnames of all passengers you will be checking in and have the Booking Reference/PNR from your eTicket.
When you have the necessary information:
Visit the Online Check-in page.
Enter your surname and Booking Reference/PNR to initiate your check-in.
Select the passengers you'd like to check in.
You may be asked to enter Advanced Passenger Information if required by the destination country.
You will then have the option of changing seats and adding any missing Skywards numbers before finalising your online check-in.
Once you've completed the check-in process, you'll be issued an online check-in receipt or an eBoarding Pass (available at select airports) for each passenger in your party. Please print* and take your Online check-in receipts or eBoarding pass with you to the airport, allowing sufficient time to complete the remaining formalities.
