From which terminal does my flight depart?

You can check your flight's departure terminal if you log in to Manage booking on Finnair.com or once you add your booking reference to the Finnair app. The departure terminal is given under the flight details.

If you don't have a booking yet, you can check the departure terminal of a Finnair flight when booking one, from the timetables or directly on the airport's homepage – from the departures or operating airlines list.
