Sit on the Left side of the plane for the best views on flights from Hanoi to Beijing. While right wins on takeoff, left provides superior views for the longer descent phase and the more dramatic Yanshan Mountains and Great Wall approach. The landing experience outweighs the brief takeoff advantage.

During takeoff from Noibai International (HAN), sit on the Right side for the best views. Right side captures the Red River Delta and Hanoi's urban sprawl immediately after departure. The aircraft climbs northwestward, so right-side seats show the river's distinctive meandering pattern and the transition from city to agricultural plains. Notable sights include: Red River Delta, Hanoi city grid, Thai Nguyen Province highlands (distant), Gulf of Tonkin (left side, receding).

When landing at Capital (PEK), sit on the Left side for the best views. Left side provides the best views during descent into Beijing. The aircraft approaches from the southeast, and left-side seats face the North China Plain and the Yanshan Mountains. You'll see the urban sprawl of Beijing and the Great Wall's ridgeline in the western hills. Notable sights include: Yanshan Mountains (western rim), Beijing urban sprawl, Ming Tombs area, Great Wall sections (visible as thin lines on ridges).

The flight from Noibai International (HAN) to Capital (PEK) takes Approximately 2 hours 45 minutes to 3 hours 15 minutes.

The flight path crosses central Vietnam and Laos, passing over the Annamite Range (visible as a north-south mountain chain with dense jungle), then enters China crossing the Red River again near the Yunnan-Guangxi border. The aircraft then tracks northeast across Guizhou and Hunan provinces, passing east of the Wuling Mountains. The Yangtze River is occasionally visible in breaks in cloud cover. As the flight approaches Beijing, it crosses the North China Plain, one of the flattest and most densely populated regions in the world.
