Passengers flying with Scandinavian Airlines System (SAS) must complete a number of pre-flight formalities through the SAS flight check in process. Typically, this entails customers receiving their boarding tickets, selecting their seats, and confirming their flight reservations. In addition to traditional counter check-in, SAS also provides online check-in via their website or mobile app, as well as check-in at airport kiosks. For their specific travel requirements, passengers can select the most practical option.
