I had problems with picking seats if my card was entered as silver in the reservation. The system would not recognize entirely that my status is gold. It would say that I can assign seats, but when I clicked on the seat selection it would fail either before loading the seatmap, or just after I selected seats. The workaround I found was to access the reservation from miles-and-more website, fix the card no. there, and then select seats at sas.dk.

I do not recall OLCI problems with tickets bought from SK. I often experience these with tickets bought from expedia, or tickets of other *A carriers serviced by SK in CPH. This is in fact one of the main reasons for me using expedia less and less.
