CPH Terminal Transfer Question
First time flyer through CPH, will be arriving from FRA and continuing onto SVO. It looks like the arrival and departure of SK flights will be through Terminal 3. I have a bit of a layover, and have access to a lounge in Terminal 2 (Novia Lounge?), how easy/hard is it to get from terminal 3 to Terminal 2 and then back to terminal 3? How long will it take, is there security check, immigration check, etc? Thanks for your help.
