Sit on the Left side of the plane for the best views on flights from London to Tromso. While the right seat wins at Heathrow departure, the left side delivers more consistently across the full flight — it faces the Norwegian coastline and fjords during the cruise over the North Sea, and provides the spectacular Tromso arrival scenery. The dramatic Arctic mountain and fjord views on descent outweigh the London departure advantage.

During takeoff from Heathrow (LHR), sit on the Right side for the best views. Heathrow typically departs eastward on runways 09L/09R, so a right-side seat gives you a southward view over central London as the aircraft climbs and turns northeast. You'll see the Thames snaking through the city, the cluster of Canary Wharf towers, and the spread of south London suburbs. Left side faces north toward the M25 corridor and Hertfordshire — less visually interesting. Notable sights include: River Thames bends through central London, Canary Wharf tower cluster, Windsor Castle and Great Park (briefly, to the west before the turn), The O2 arena dome at Greenwich.

When landing at Tromso (TOS), sit on the Left side for the best views. Tromso Airport (IATA: TOS) runway 01/19 means arrivals typically come in from the south heading north, or from the north heading south. On a flight from the southwest, the approach is usually runway 01 heading north, putting the left side facing west toward the island of Tromsøya, the city center, and Tromsdalstinden mountain. The left seat gives you the dramatic fjord scenery, the bridge connecting the island, and the Arctic Cathedral. Notable sights include: Tromsøya island and city center, Tromsdalstinden mountain (1,238m) to the east of the city, Tromsø Bridge and Sandnessund strait, Ullsfjorden and surrounding snow-covered peaks.

The flight from Heathrow (LHR) to Tromso (TOS) takes Approximately 3 hours 15 minutes.

The route tracks northeast over the North Sea, passing east of the Shetland Islands, then crossing the Norwegian coast near Bergen or Ålesund where the western fjords become visible. Further north the route passes over the Lofoten Islands area and the dramatic coastal mountain ridges of Nordland and Troms counties before descending into Tromso. The midnight sun or polar twilight may be visible depending on season.
