According to Petteri Kostermaa, Finnair's vice-president of network strategy and traffic planning, the extra flights will connect the airline's Asian route network with the US by allowing for quick connections via Helsinki from cities in Asia to New York.
Detailing the new flights' schedule, a Finnair statement said: "Finnair flight AY007 will depart from Helsinki on Wednesdays, Fridays and Sundays at 17:10 [local time], connecting with flights from Beijing, Delhi, Hong Kong, Nagoya, Osaka, Seoul, Shanghai and Tokyo."
The flights will arrive at New York JFK Airport at 18:50 (local time), with return flight AY008 departing from the Big Apple at 22:40.
The new flights, which take Finnair's total between the two cities to ten a week, will also allow for connections with the airline's European route network.
Finnair announced earlier this month that it would temporarily suspend its flights to Mumbai from May until the middle of October.
