Finnair and British Airways have firmed up their "Nordic alliance", which will take the form of codesharing on 15 flights between London and Helsinki in Finland and Stockholm in Sweden.
The link will see a new service between Helsinki and London Gatwick, while Helsinki-Stockholm-Manchester flights will be included from May.
Finnair recently signed a codeshare agreement with LOT Polish Airlines. Both airlines already codeshare with BA's German subsidiary Deutsche BA. Finnair also codeshares with Iberia, which is tipped to link with BA.
