Sit on the Right side of the plane for the best views on flights from Hong Kong to Hanoi. While left seats offer superior takeoff views of Hong Kong's harbor and skyline, right seats provide the more dramatic and sustained geography on approach to Hanoi, with clear views of the Red River delta and city approach. The landing experience outweighs the takeoff advantage.

During takeoff from Hong Kong International (HKG), sit on the Left side for the best views. HKG typically departs runway 25L or 25R (westbound). Left seats face north during initial climb, giving direct views of Victoria Harbour, Kowloon, and the New Territories before the aircraft turns northwest toward Hanoi. Notable sights include: Victoria Harbour with Star Ferry routes, Kowloon skyline (including West Kowloon waterfront), New Territories urban sprawl, and the Lantau Island runway complex receding behind.

When landing at Noibai International (HAN), sit on the Right side for the best views. HAN typically lands runway 05L or 05R (northeastbound). Right seats face southeast during approach, providing views of the Red River delta, Hanoi's urban core, and the approach path over agricultural land and water features before touchdown. Notable sights include: Red River with its distinctive meanders and brown water color, Hanoi city center with Hoan Kiem Lake visible as a small dark rectangle, surrounding patchwork of rice paddies and fish farms in the delta, and the approach corridor over flat terrain.

The flight from Hong Kong International (HKG) to Noibai International (HAN) takes Approximately 2 hours 45 minutes to 3 hours 15 minutes.

The flight path crosses the Gulf of Tonkin at cruise altitude (around 30,000-35,000 feet). At midpoint, the aircraft is over open water with no significant landmarks visible. The coastline of northern Vietnam becomes visible on the right side approximately 30-40 minutes before landing, with the Haiphong area and coastal features appearing as the aircraft begins descent toward Hanoi. The Red River delta becomes increasingly detailed as the aircraft descends below 10,000 feet.
