Sit on the Right side of the plane for the best views on flights from Siem Reap to Hanoi. While landing views favor the left, the takeoff experience on the right side—featuring the expansive Tonlé Sap Lake system—provides more sustained and visually distinctive scenery. The lake's scale and unique appearance outweigh the urban views during landing.

During takeoff from Siem Reap-Angkor International Airport (SAI), sit on the Right side for the best views. Right-side seats offer views of the Tonlé Sap Lake and its extensive water systems during the initial climb-out heading northeast. The lake's irregular shoreline and surrounding wetlands are distinctive from altitude and visible for the first 10-15 minutes of flight. Notable sights include: Tonlé Sap Lake (Cambodia's largest freshwater body), Siem Reap River delta, agricultural plains of northwestern Cambodia, scattered villages and rice paddies.

When landing at Noibai International (HAN), sit on the Left side for the best views. Left-side seats provide excellent views of the Red River and Hanoi's urban sprawl during descent. The Red River's distinctive reddish-brown color and meandering path through the city are clearly visible, along with the dense urban development of Vietnam's capital. Notable sights include: Red River (with characteristic reddish sediment coloration), Hanoi's urban districts and street grid, Long Biên Bridge area, Hoan Kiem Lake in central Hanoi.

The flight from Siem Reap-Angkor International Airport (SAI) to Noibai International (HAN) takes Approximately 1 hour to 1 hour 15 minutes.

The flight path crosses from northwestern Cambodia into northeastern Thailand briefly, then enters Laos before crossing into northern Vietnam. Notable features include the Mekong River valley (visible from altitude as a broad, winding waterway with agricultural plains), the transition from Cambodian lowlands to the more mountainous terrain of the Laos-Vietnam border region, and scattered karst formations in northern Laos. The terrain gradually becomes more hilly and forested as the aircraft approaches the Red River Delta.
