Handling of opups seems to be quite weird at SAS. It looks like to be based only on the discretion of the gate agents. It seems some prefer SK*G, some prefer expensive revenue tickets, some pick by names they like.
On my last TATL SFO-CPH they opuped round about 15 pax (10to Y, 5 to C), most of them without any status with SK or *G.
A clear, consistent and transparent procedure how opups are cleared would be a great.
