When you book a package holiday with SAS Holidays, seat reservation is not included at the time of booking. Instead, the seat is automatically assigned by the airline at check-in.
If you wish to choose a seat in advance, you can do so directly via the SAS website at the earliest 14 days before departure. Use the booking reference stated for each flight in your travel documents. Advance seat reservation is possible up to 24 hours before departure and may be subject to a fee.
If you do not make an active selection, a seat will be automatically assigned when check-in opens, which usually occurs 24 hours before departure.
