Yes. We advise all passengers to allow more time for visa checks at the airport. The check-in and Visa/Document Check desks are open at least 2 hours before your departure time and close strictly 40 minutes prior to the scheduled time of departure. If you have not had your visa check done before this deadline, you will not be allowed to travel, and you will not be entitled to a refund of the missed flight.
All visa checks must be done before you travel through airport security. You should check your departure time and ensure you have planned to allow sufficient for all these visa checks.
