Sit on the Left side of the plane for the best views on flights from Siem-reap to Phnom-penh. While takeoff favors the right for Tonlé Sap views, the landing approach provides more dramatic and sustained visual interest with the river, urban landscape, and Mekong confluence. The landing sequence on a westbound approach offers superior geographic definition and more varied landmarks.

During takeoff from Siem Reap (REP), sit on the Right side for the best views. REP typically departs runway 06 (northeast heading). Right-side seats face toward the Tonlé Sap Lake and its extensive floodplain wetlands, which dominate the landscape immediately north and east of the airport. Left seats look inland toward forested terrain with less distinctive visual features. Notable sights include: Tonlé Sap Lake (massive freshwater body with visible water hyacinth mats and fishing villages), Siem Reap River valley (winding waterway visible as dark linear feature), extensive rice paddies and wetland complexes (geometric patchwork of flooded fields), forested uplands to the northeast (Kulen Mountains foothills, appearing as darker terrain texture on horizon).

When landing at Pochentong International (PNH), sit on the Left side for the best views. PNH typically lands runway 09 (eastbound approach). Left-side seats provide views of the Tonlé Sap River and Phnom Penh's urban sprawl as the aircraft descends on final approach. The river's distinctive meanders and the city's dense development create strong visual interest. Right seats face toward rural floodplain with less urban definition. Notable sights include: Tonlé Sap River (major waterway with visible bends and boat traffic, appearing as dark ribbon), Phnom Penh urban area (dense building clusters and street grid visible at lower altitudes, concentrated on both sides of river), Mekong River confluence (visible as darker, wider water body merging from the southeast), extensive floodplain wetlands and rice paddies (geometric field patterns surrounding the city).

The flight from Siem Reap (REP) to Pochentong International (PNH) takes Approximately 45-55 minutes.

The flight path crosses the Tonlé Sap Lake's eastern and central regions, passing over extensive floodplain wetlands and rice paddies. The lake's surface is typically visible with fishing villages, floating structures, and water vegetation patterns. As the aircraft descends toward Phnom Penh, the Tonlé Sap River becomes increasingly prominent, with its characteristic meanders visible. The transition from rural floodplain to urban development occurs gradually over the final 15-20 minutes of flight, with the Mekong River becoming visible in the approach phase.
