Left seats capture the dramatic departure over the Sichuan Basin foothills and the spectacular arrival into the Kathmandu Valley. While right seats offer good takeoff views, the landing view—descending directly into a mountain-ringed basin—is geographically more striking and memorable.

Flight Path
Chengdu to Kathmandu is 1,138 miles (1,831 km), a flight of about 2 hours 15 minutes.
The flight crosses the Tibetan Plateau's eastern edge, passing over the Hengduan Mountains (visible as a series of north-south trending ridges and deep valleys around 1.5 hours into flight). The terrain transitions from the Sichuan Basin's foothills to increasingly rugged alpine topography. Major river valleys—including the Yangtze and its tributaries—cut through this region as dark linear features. By the final 45 minutes, the Mahabharata Range and Kathmandu Valley become visible as the aircraft descends into Nepal's airspace. The entire route follows a southwest trajectory across progressively higher terrain.
