Sit on the Left side of the plane for the best views on flights from London to San Francisco. The SFO approach on the left side is one of the great urban arrival views in commercial aviation — the full sweep of San Francisco Bay, the city, and both major bridges in a single frame. The Heathrow departure on the right is excellent but shorter-lived. Left side also captures Greenland's ice sheet and the Canadian Rockies on the polar routing, making it the stronger choice across the full flight.

During takeoff from Heathrow (LHR), sit on the Right side for the best views. Heathrow departures on the westbound runways (09L/09R departing east to west) typically swing north after takeoff. Right side gives you a clear view south over central London as the aircraft climbs and turns. You'll see the Thames snaking through the city, the cluster of Canary Wharf towers, and on a clear day the full sweep of the city grid out to the M25. Notable sights include: River Thames through central London, Canary Wharf tower cluster, Windsor Castle and Great Park to the southwest, the green expanse of Richmond Park.

When landing at San Francisco International (SFO), sit on the Left side for the best views. SFO sits on the west shore of San Francisco Bay, and aircraft typically approach from the southeast over the bay on runways 28L/28R. Left side gives you the full panorama of the San Francisco Peninsula, the Bay Bridge, and the city skyline as you descend. The Golden Gate Bridge is visible to the north across the water on the left side. Notable sights include: San Francisco Bay, San Francisco city skyline and downtown, Bay Bridge, Golden Gate Bridge visible to the north.

The flight from Heathrow (LHR) to San Francisco International (SFO) takes Approximately 10 to 11 hours westbound.

The route typically follows a polar arc tracking northwest over Ireland, then across the North Atlantic. Southern Greenland's ice cap and fjord coastline are visible mid-Atlantic. The route then crosses the Hudson Bay region and the Canadian Shield's lake-dotted boreal landscape. Over Canada, the Rocky Mountains appear as a dramatic corrugated ridge running north-south. Descent begins over northern California, with the Sierra Nevada visible to the east before the Bay Area comes into view.
