Welcome to FT.
Please note that the Finnair two-letter code is AY.
Make sure to preorder your main course. Go to the AY website to see your booking and pick your main course choices. It is free of charge and works for both flights.
Right at the beginning of the flight, ask the FA (flight attendant) for a memory foam pillow, which is a lot better than the flimsy ones that are waiting at your seat. Socks, lip balm and mouthwash are also available on request.
As there are two of you travelling, the D&H seats will work well for you.
