Sit on the Left side of the plane for the best views on flights from Hong Kong to London. Left side wins at both ends of the flight. Over the route itself, the left side also faces south over Central Asia, giving better views of the Himalayas and Tibetan Plateau during the early portion of the flight, and the Caspian Sea and Caucasus region in the middle section.

During takeoff from Hong Kong International (HKG), sit on the Left side for the best views. HKG departures on runway 07R head northeast, putting the left (north) side facing Lantau Island, the dense urban sprawl of Kowloon and Hong Kong Island, and Victoria Harbour. The right side faces open South China Sea with little of interest. Notable sights include: Victoria Harbour and Hong Kong Island skyline, Kowloon Peninsula grid, Lantau Peak (934m), Ma On Shan ridgeline to the northeast.

When landing at Heathrow (LHR), sit on the Left side for the best views. Heathrow's most common landing direction is runway 27L/27R, approaching from the east over central London. The left side faces south over the Thames, giving views of the City of London, Canary Wharf, and the river's distinctive bends. The right side faces north over suburban Middlesex with far less visual interest. Notable sights include: Thames river bends through central London, Canary Wharf tower cluster, The City of London, Windsor Castle and Windsor Great Park to the west on final approach.

The flight then crosses Afghanistan and Iran before reaching the Caspian Sea, the Caucasus Mountains, and the Black Sea region.
