FI lounge access at CPH:
Icelandair Saga Class passengers and Gold card members: SAS lounge at Terminal 3. Open from 05:30 - 23:00.
Icelandair Comfort Class passengers and Silver card members: Aviator lounge
I'll try to get in with my BP (which should be the SK two flights on one BP format), if they don't allow it (see above, I have a FI onward flight in economy and only *G), I'll move on and use my PP card to check out the aviator and aspire lounge
On the way back CPH should be no issue in Plus and *G, in KEF I can get into the Saga lounge as 'Eco comfort' passenger:

My point was that I'm assigned seat 1C on the way back, which is definitely Saga Business territory. If you look at the seat map trying to book Eco comfort on the way back, the last 2-2 seater row (6) shows as available for ASR, but 1-5 is for Business class only.
Not really bothered by all this on a 3h flight, just curious!
