As Finnair Plus Platinum Lumo/Platinum/Gold/Silver member, can I take one carry-on bag free of charge when travelling with a Superlight ticket?

Yes, Finnair Plus Silver, Gold, Platinum and Platinum Lomo members can take one complimentary carry-on bag (55cm x 44cm x 23cm) on short-haul flights within Europe when travelling with an Economy Superlight ticket that otherwise would only include a small bag (40cm x 30cm x 15cm) placed under the front seat. This applies to bookings made on or after 1 June 2023.
