It is all on one booking, and the ticket was sold by SAS. So I guess I get then 1+1=2. I was somehow hoping that it would be 1+2=3 as the SK flight is the "most significant" one, but apparently not.
Of course this makes the SK*G benefit of having 1+2 bags a bit unusable if one connects. Perhaps according to rules, but still somewhat unexpected... in particular because they told me differently on the phone while booking.
Thanks!
