Sit on the Left side of the plane for the best views on flights from Delhi to Hanoi. While takeoff favors the right, the landing approach offers more dramatic and distinctive scenery—the Red River delta and Hanoi's geography are more visually striking than Delhi's departure. The left side captures the most memorable portion of this flight.

During takeoff from Indira Gandhi International (DEL), sit on the Right side for the best views. Right-side seats capture the Yamuna River and Delhi's urban sprawl as you climb eastward. The river's distinctive curves and the contrast between developed areas and surrounding plains are clearly visible during the initial climb-out. Notable sights include: Yamuna River (winding through Delhi), Delhi urban grid and suburbs, Aravalli Hills (distant southern horizon), Indo-Gangetic Plain extending northeast.

When landing at Noibai International (HAN), sit on the Left side for the best views. Left-side seats offer excellent views of the Red River delta and Hanoi's geography during descent. The river's distinctive red-brown color, the dense patchwork of rice paddies, and the city's position within the delta are all clearly visible from the left side as you approach from the southwest. Notable sights include: Red River and its delta (distinctive reddish water), Hanoi city center and urban sprawl, rice paddies and agricultural grid pattern, Gulf of Tonkin (visible on clearer days to the northeast).

The flight from Indira Gandhi International (DEL) to Noibai International (HAN) takes Approximately 3 hours 15 minutes.

The flight path crosses the Indo-Gangetic Plain, then transitions over the Ganges River valley and eastern India. Notable midpoint features include the Ganges River (visible as a major waterway around 1.5 hours into flight), the transition from Indian plains to the foothills of the Eastern Himalayas, and the Assam region with its river systems. As you approach Vietnam, the landscape becomes increasingly mountainous with the Annamite Range visible, followed by the descent into the Red River delta. The Mekong River system becomes visible in the final approach phase if flying slightly south of the direct route.
