Sit on the Right side of the plane for the best views on flights from Bangkok to Phnom-penh. Right-side seats capture the Chao Phraya delta and Bangkok's geography during departure, then offer views of Cambodia's forested interior and the approach to Tonlé Sap during descent. Left seats miss the Bangkok departure entirely and only gain advantage during the final 15 minutes of landing.

During takeoff from Bangkok International (BKK), sit on the Right side for the best views. BKK typically departs eastbound (runways 01L/01R). Right-side seats face north initially, offering views of the Chao Phraya River delta and Bangkok's sprawl before turning southeast toward Cambodia. Left seats see only industrial areas and the airport's western perimeter. Notable sights include: Chao Phraya River delta with its distinctive braided channels, Bangkok urban grid extending north, Don Mueang Airport (visible as a secondary airfield to the northwest), Samut Prakan coastal plains.

When landing at Pochentong International (PNH), sit on the Left side for the best views. PNH typically lands westbound (runway 03). Left-side seats descend facing the Tonlé Sap Lake's northern shore and approach over the lake itself, providing extended views of Cambodia's largest freshwater body and surrounding wetlands. Right seats see only inland forest and the airport's eastern approach. Notable sights include: Tonlé Sap Lake (massive freshwater lake with seasonal water level variation), Phnom Penh city on the eastern bank, Mekong River confluence, flooded forest and wetland zones around the lake's perimeter.

The flight from Bangkok International (BKK) to Pochentong International (PNH) takes Approximately 1 hour 15 minutes.

The flight path crosses the Thai-Cambodian border near the Dangrek Mountains (visible as low, forested ridges on the horizon around 30 minutes into flight). The terrain transitions from the flat Chao Phraya delta to rolling, heavily forested Cambodian countryside. The Tonlé Sap Lake becomes visible approximately 20 minutes before landing, appearing as a massive pale water body dominating the landscape. No major cities are visible along the route except at departure and arrival.
