Tromso will become BA’s most northerly destination from 1 December, when it will operate from Heathrow on Thursday and Sunday, with return fares from £153. Flights will operate until 27 March.
BA said: “The Norwegian city is known as being one of the best places in the world to see the Aurora Borealis, thanks to its central position in the northern lights’ oval.
“With average winter temperatures ranging from 0°C to -5°C, the destination’s abundant snowfall also lends itself to winter activities including skiing, mountaineering and whale watching.”
It added the city, which is in the Arctic Circle, is also popular with those who enjoy exploring Christmas markets.
