Finnair has announced an additional frequency for its popular Heathrow-Helsinki service.

New evening flights means the carrier will operate up to eight daily flights between on the route during the summer 2020 season.

Flight AY1347 will depart Helsinki at 1715, landing into Heathrow at 1820, with the return leg AY1348 leaving London at 2030, landing back into the Finnish capital at 0120 the following day.

The new frequency will increase capacity on the route by 10 per cent, adding 420 flights between the two cities this summer.

Finnair says that the new service “will offer travellers the chance to experience the land of the midnight sun during the peak summer season, where nights are almost as light as in the daytime and where evening events come to life”.

The extra frequency will be served by the carrier’s A319 aircraft, as opposed to the A350 and A330s which operate on some of Finnair’s Heathrow-Helsinki flights, and which offer a fully flat bed in business class.

Finnair has confirmed that the slot for the extra Heathrow-Helsinki service has come from Etihad.

Commenting on the news Andrew Fish, Finnair general manager UK and Ireland and Benelux, said:

“Finnair’s presence in London and in the UK has been growing steadily over the past few years and we are pleased to add capacity so visitors can enjoy more of the beauty of the midnight sun in Helsinki this summer.

“By adding this new evening flight for the summer sesaon, we will be able to offer even more flexibility and network connections for our customers.”

Finnair is set to launch flights between Helsinki and Busan on March 30, becoming the first carrier to operate direct, nonstop flights between Europe and South Korea’s second largest city.
