Sit on the Left side of the plane for the best views on flights from Phnom-penh to Hong Kong. While takeoff offers lake and river views from the right, the landing approach into Hong Kong provides more dramatic and visually distinctive scenery with Victoria Harbour and the iconic skyline. The contrast between water and dense urban development is more compelling than the delta landscape at departure.

During takeoff from Pochentong International (PNH), sit on the Right side for the best views. Right-side seats offer views of the Tonlé Sap Lake system and the Mekong River delta as the aircraft climbs northeastward. The lake's extensive water surface and river channels are distinctive from altitude and visible during the initial climb-out phase. Notable sights include: Tonlé Sap Lake (large freshwater lake to the west), Mekong River delta channels (braided waterways), Phnom Penh city grid (urban sprawl below), Cardamom Mountains (distant southwestern horizon).

When landing at Hong Kong International (HKG), sit on the Left side for the best views. Left-side seats provide excellent views of Victoria Harbour, Hong Kong Island's urban landscape, and Kowloon Peninsula during the approach from the northwest. The harbor's distinctive shape and the contrast between water and dense urban development are striking from altitude. Notable sights include: Victoria Harbour (deep blue water body between Hong Kong Island and Kowloon), Hong Kong Island skyline (Central District high-rises), Kowloon Peninsula (dense urban grid), New Territories (green hills to the north).

The flight from Pochentong International (PNH) to Hong Kong International (HKG) takes 2h 15m.

Hainan Island (large island with mountainous terrain visible as you pass east of it), the Gulf of Tonkin coastline (Vietnam's northeastern coast with limestone karst formations), and the South China Sea's open water with occasional fishing vessel activity. The flight path typically tracks northeast across the Gulf of Tonkin, offering glimpses of Vietnam's coastal provinces including Quang Ninh Province's distinctive karst landscape around Ha Long Bay area (though typically at the edge of visibility depending on atmospheric conditions).
