Sit on the Right side of the plane for the best views on flights from London to Singapore. The right side wins overall due to the spectacular London departure views over the Thames and city skyline, which are among the best urban aerial views in the world. The landing views from the left are excellent but the right side during landing still offers reasonable views of Singapore. For the full flight, right side also captures better views over the Hindu Kush and Himalayas on the northern route, as the aircraft tracks east and these ranges appear to the right (south) of the flight path.

During takeoff from Heathrow (LHR), sit on the Right side for the best views. Heathrow's dominant departure runway is 27L/27R heading west, then aircraft typically turn south or southeast toward the continent. A right-side seat gives you views over central London as the aircraft banks left after departure — you can see the Thames snaking through the city, the City of London skyline, and Canary Wharf's cluster of towers. Left side faces away toward the M4 corridor and suburban sprawl. Notable sights include: Thames River bends through central London, Canary Wharf tower cluster, The Shard and City of London skyline, Windsor Castle and Great Park (briefly, to the right before the turn).

When landing at Singapore Changi (SIN), sit on the Left side for the best views. Changi typically uses runways 02L/02R or 20L/20R. On approach from the northwest over the Strait of Malacca and the Malay Peninsula, a left-side seat gives views over the southern tip of the Malay Peninsula, the Singapore Strait, and the city skyline including Marina Bay. Right side faces east toward open South China Sea. Notable sights include: Marina Bay Sands and Singapore CBD skyline, Johor Strait between Malaysia and Singapore, Sentosa Island, Singapore Strait shipping lanes.

The flight from Heathrow (LHR) to Singapore Changi (SIN) takes Approximately 13 to 14 hours.

The route typically tracks southeast over France and the Alps, then across the Adriatic, Greece, and Turkey before crossing Iran and Pakistan. The Hindu Kush range is visible over Afghanistan, and on clear days the western Himalayas appear as a vast white wall to the south over northern Pakistan and India. The Bay of Bengal is crossed before landfall over the Malay Peninsula through Thailand and Malaysia, with the Andaman Sea visible to the right and the Gulf of Thailand to the left on the final southern leg.
