After flying in from Tallinn, we had a short transit in Helsinki so popped into Finnair's non-Schengen area business class lounge.
The lounge is located just before Gate 50, Gate 50 is actually a small wing with a series of gates called 50A-M where most Finnair non-Schengen flights depart from. The lounge is conveniently located at the top of this wing, a short walk to any of the Gate 50 departure gates. Conveniently there is also a duty free store right next to the lounge, making it easy to pop out for any last minute purchases.
