Sit on the Right side of the plane for the best views on flights from Phnom-penh to Bangkok. Right side captures the most geographically significant features: Tonlé Sap Lake's dramatic expanse during takeoff and the approach to Bangkok's river system during descent. The flight path itself runs generally northwest-to-southeast, making the right side consistently favorable for viewing the major water features that define both regions.

During takeoff from Pochentong International (PNH), sit on the Right side for the best views. Right side offers clear views of the Tonlé Sap Lake system and its extensive waterways as the aircraft climbs northwestward. The lake's distinctive shape and surrounding wetlands are prominent features during the initial climb-out phase. Notable sights include: Tonlé Sap Lake (massive freshwater lake dominating the landscape), Phnom Penh city grid (visible as urban sprawl below), Mekong River confluence (visible as dark water channels), agricultural plains extending to the horizon.

When landing at Bangkok International (BKK), sit on the Left side for the best views. Left side during descent provides excellent views of the Chao Phraya River's distinctive meanders as they approach Bangkok, plus the sprawling urban landscape of the metropolitan area. The river's serpentine pattern is a defining feature of the approach corridor. Notable sights include: Chao Phraya River with its characteristic bends (visible as dark water curves through the city), Bangkok's urban sprawl (high-rise clusters in Silom and Sukhumvit districts), Don Mueang area (flat terrain with industrial zones), Gulf of Thailand coastline (distant southern horizon).

The flight from Pochentong International (PNH) to Bangkok International (BKK) takes 1h 15m.

The flight crosses the Cambodian plains with scattered agricultural areas and small towns. The Battambang Province region lies to the west (left side) with its agricultural landscape. The direct route passes over relatively flat terrain with occasional river valleys. As the aircraft approaches Thailand, the landscape transitions from Cambodian plains to Thai lowlands. The Chao Phraya River basin becomes increasingly visible during the descent phase, with its characteristic meanders becoming more pronounced as the aircraft approaches Bangkok.
