Platinum Icelandair, Premium Icelandair and Business cardholders can use the express check-in at the priority check-in desk at Leifstöð, when flying with Icelandair scheduled flights. This applies to all fares. The card must be presented at check-in. Note that the express check-in line only checks in the cardholder of the aforesaid card types, so if the cardholder is traveling with family or friends where the group is checking in together, we point out that a general check-in line is required.
