Sit on the Left side of the plane for the best views on flights from Siem-reap to Hanoi. While the takeoff offers good views of Tonlé Sap Lake, the landing descent provides more sustained and visually distinctive scenery. The Red River Delta's intricate agricultural pattern and Hanoi's urban landscape are more visually compelling and geographically significant than the takeoff views.

During takeoff from Siem Reap (REP), sit on the Right side for the best views. Right-side seats offer views of the Tonlé Sap Lake as the aircraft climbs northwest from Siem Reap. The lake's extensive water surface and irregular shoreline are distinctive from altitude, and you'll see the patchwork of flooded forests and villages along its edges during the initial climb. Notable sights include: Tonlé Sap Lake (massive freshwater body immediately west of airport), Siem Reap city grid (visible below during climb), Kulen Mountains (distant ridge to the north), flooded forest zones along lake margins.

When landing at Noibai International (HAN), sit on the Left side for the best views. Left-side seats provide excellent views during descent into Hanoi. You'll see the Red River delta's intricate network of waterways, rice paddies, and the river itself snaking through the landscape. The approach also reveals Hanoi's urban sprawl and the surrounding patchwork of agricultural fields characteristic of the delta. Notable sights include: Red River (major waterway visible throughout descent), Hanoi city sprawl (urban grid visible from 8,000-10,000 feet), Red River Delta agricultural fields (extensive patchwork of paddies and waterways), Thái Nguyên highlands (distant ridges to the northwest).

The flight from Siem Reap (REP) to Noibai International (HAN) takes Approximately 1 hour 15 minutes.

The flight path travels north-northeast from Siem Reap across central Cambodia. Notable features include the Tonlé Sap Lake region (initial climb), the transition into Cambodia's central plains with scattered settlements and waterways, and the approach to the Vietnam border near the Mekong River system. The aircraft crosses into Vietnam over the northern Cambodian plateau before descending into the Red River Delta. The Annamite Range (eastern border mountains) remains distant to the east throughout the flight but may be visible as a faint ridge line in clear conditions.
