SAS' Scandinavian Lounge requires *A to get in. (They have Business Lounge for non-*G C class pax.)
However, if you hold an F class BP (on another * carrier since SK has no F) then you can get into the Scandi Lounge. In CPH the main difference is hard liquor and free domestic phone calls.
I am pretty sure that the Thai F lounge in BKK had a *G logo. I was about to go in but I decided not to enter when they told me that there were no bathrooms. (The main reason for entering after being in the bathroomless SAS lounge.)
