SEA → LHR
Which side of the plane to sit from Seattle Tacoma International Airport (Seattle) to London Heathrow Airport (London)?
Left Side of the Plane
The left side is superior for this northern Great Circle route, offering incredible views of the Greenland ice cap and Baffin Island, along with the highest probability of seeing the Aurora Borealis.
Canadian Rockies
Stunning views of the jagged, snow-capped peaks of British Columbia and Alberta shortly after takeoff.
Baffin Island
Dramatic arctic wilderness featuring massive fjords and vast frozen tundras in Northern Canada.
Greenland Ice Sheet
The flight's crown jewel, showing immense glaciers and deep blue ice melt pools along the coast.
Aurora Borealis
On overnight flights, the northern horizon often glows with green and purple solar activity.
North London
Views of Wembley Stadium and the northern suburbs during the standard arrival patterns.
Sit on the left for the best lighting on the Greenland glaciers during daylight flights. If flying between September and April, choose this side for a high chance of spotting the Northern Lights over Northern Canada and the Atlantic. Use a blanket to cover your head and the window to block cabin light for the best night viewing.
Mount Rainier
If the flight departs to the south before turning north, you will see the massive volcanic peak dominating the horizon.
Canadian Prairies
Vast, geometric patterns of agricultural land stretching across Saskatchewan and Manitoba.
Bristol Channel
Aerial views of the Welsh coastline and the Severn Bridge as you enter UK airspace.
Windsor Castle
A close-up view of the historic royal residence during the final descent into Heathrow.
Central London Skyline
The most iconic view, including the London Eye, The Shard, and Tower Bridge when landing on Runway 27.
The right side is best for the arrival into London. Most flights land facing west; if you are tracking in from the south or east, the right side provides a spectacular 'flightseeing' tour of the city center. Keep your camera ready about 10 minutes before landing for the best shots of the Thames.
