SAS Customers have four methods of check-in: online check-in, mobile check- in, and check-in at an airport kiosk or counter. With online check-in, passengers can choose their seat or change their seat 22 hours to 1 hour before departure. Air ticket buyers with Scandinavian Airlines can purchase lounge access for 30 USD.
