Sit on the Right side of the plane for the best views on flights from Phnom-penh to Ho Chi Minh City. Right-side seats capture the most dramatic geography: the Tonlé Sap system and Cardamom Mountains on departure, then the Mekong Delta's waterway complexity and Can Tho region during descent. Left offers good delta views but misses the lake and mountains entirely.

During takeoff from Pochentong International (PNH), sit on the Right side for the best views. PNH typically departs eastbound (Runway 03/21 favors 03 for eastbound traffic). Right-side seats capture the Tonlé Sap Lake system and the sprawling Phnom Penh urban area receding westward, plus the Cardamom Mountains rising along the southwestern horizon. Notable sights include: Tonlé Sap Lake (vast freshwater body dominating the western view), Phnom Penh city grid (visible as urban sprawl directly below and behind), Cardamom Mountains (distant southwestern ridge), Mekong River confluence (visible as dark water channels threading through the delta).

When landing at Tansonnhat International (SGN), sit on the Left side for the best views. SGN approaches from the southwest (Runway 25L/25R favors westbound arrivals). Left-side seats offer the best view of the Saigon River's distinctive meanders through Ho Chi Minh City, the Mekong Delta's intricate waterway network, and the Can Tho region's agricultural patchwork during descent. Notable sights include: Saigon River (dark, winding through the city center), Mekong Delta waterways (complex network of canals and channels visible as linear features), Can Tho city and surrounding rice paddies (geometric agricultural fields in greens and browns), Vung Tau peninsula (low coastal landform on the southeastern horizon).

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

The flight path crosses the Mekong Delta's northern reaches, passing over the Tien Giang and Ben Tre provinces. The terrain transitions from Cambodia's flatter Tonlé Sap basin to Vietnam's more densely waterlogged delta system. At cruise altitude (around 25,000 feet), the Mekong River's main channel and its distributaries become increasingly visible as dark linear features threading through the agricultural landscape. The border region between Cambodia and Vietnam is unmarked from altitude but corresponds to a subtle shift in settlement density and waterway patterns. No major mountains are visible during cruise—the terrain remains uniformly flat delta throughout the flight path.
