Someone without status who has bought a classic J ticket (I'd assume all travel classes are affected) might be rather surprised to find out that they can't select seats for free even during check-in.
At the same time as the baggage-related changes, we are making changes to the seat selection practices. With a Superlight, Light, or Classic ticket, you can choose your preferred seat by purchasing it in advance, and if you do not wish to do that, we will choose a seat for you. This means that complimentary seat selection is no longer available during check-in for these tickets. Finnair Plus members continue to have their current advance seat reservation benefit.
