UK regional operator Flybe is to conduct feeder routes on behalf of Oneworld alliance carrier Finnair, under an agreement which will involve basing some of its aircraft at Helsinki.
The flights - which will operate with Finnish cabin crew - will commence at the end of October.
Under the co-operation pact Flybe, which uses Bombardier Q400s and Embraer regional jets, will station three aircraft at the Finnish capital.
These will be used on domestic feeder routes from Tampere and Turku as well as from the Estonian capital Tallinn.
"We aim to strengthen our feeder operation on routes important for Finnair during the coming winter traffic season," says Finnair senior vice-president for resources management Ville Iho.
Finnair says the agreement could be extended if required. Iho says: "[Flybe's] fleet and production structure support the
operation of short routes.
"Expanding our cooperation base will give us flexibility to modify our feeder traffic network according to needs."
