Keflavik to London flight path: KEF to LHR

Sit on the Left side of the plane for the best views on flights from Keflavik to London. The left side wins overall thanks to the dramatic volcanic terrain and coastline visible right after takeoff from Iceland, which outweighs the brief London skyline glimpse on arrival, especially given the many hours of featureless ocean in between.

During takeoff from Keflavik Nas (KEF), sit on the Left side for the best views. Departing KEF on runway 19 and banking left toward the southeast for the UK, passengers on the left get a sweeping view of the volcanic Reykjanes Peninsula with its black lava fields, geothermal steam plumes, and rugged coastline before the aircraft heads out over open water. Notable sights include: Reykjanes Peninsula lava fields, Krýsuvík geothermal area, southwest Iceland coastline, Atlantic shoreline cliffs.

When landing at Heathrow (LHR), sit on the Right side for the best views. On the descent into LHR under typical westerly operations, arrivals from the north often curve south past London before turning onto final approach, putting the Thames and London's skyline on the right side of the aircraft. Notable sights include: River Thames, Central London skyline, M25 orbital motorway, Home Counties patchwork fields.

The flight from Keflavik Nas (KEF) to Heathrow (LHR) takes 3h 15m.

Extended stretch of open North Atlantic Ocean, with the flight path passing south of the Faroe Islands and occasionally within sight of Scotland's Outer Hebrides or the northern Scottish coastline before crossing into England.
