Sit on the Left side of the plane for the best views on flights from Hong Kong to Brussels. While takeoff favors the right for Hong Kong's harbor views, the landing approach into Brussels from the east provides superior geography on the left side—the Meuse River valley and Ardennes plateau are more visually distinctive than the flat approach from the right. Left wins the overall route.

During takeoff from Hong Kong International (HKG), sit on the Right side for the best views. Hong Kong International typically departs runway 25L or 25R (westbound). Right-side seats offer immediate views of Victoria Harbour and Kowloon Peninsula as you climb out over the water, while left seats face the New Territories and mountains inland. Notable sights include: Victoria Harbour (directly below during initial climb), Kowloon Peninsula skyline, Hong Kong Island's northern shore, Lion Rock (distant peak to the north).

When landing at Brussels Natl (BRU), sit on the Left side for the best views. Brussels National uses runways 01/19 and 07/25 depending on wind. On typical westbound arrivals, you'll approach from the east. Left-side seats provide views of the Meuse River valley and the Ardennes plateau as you descend through Belgian airspace, while right seats face the flat Flanders plains. Notable sights include: Meuse River (winding through forested terrain), Ardennes plateau (rolling, densely forested landscape), Brussels city center (visible as urban sprawl), Zaventem airport infrastructure.

The flight from Hong Kong International (HKG) to Brussels Natl (BRU) takes Approximately 12.5 to 13.5 hours.

The flight path crosses the Tibetan Plateau and Hindu Kush mountains (visible around 4-5 hours into flight), then transits over the Caspian Sea region, southern Russia, and Eastern Europe. The Carpathian Mountains become visible during the final descent phase over Romania and Hungary. The Alps appear briefly on the approach to Belgium, weather permitting.
