Sit on the Right side of the plane for the best views on flights from London to Chengdu (Jianyang). Right side scores higher due to the dramatic Sichuan Basin approach with visible mountain ranges (Longquan, Qinling foothills), river valleys, and the contrast between mountainous terrain and urban sprawl during landing. Left side's takeoff advantage over London is outweighed by the landing phase's superior terrain drama on the right, and the 11+ hour flight duration means landing scenery carries significant weight.

During takeoff from Heathrow (LHR), sit on the Left side for the best views. Left side captures the Thames estuary, London's urban sprawl, and the Chiltern Hills during climb-out from Heathrow. Right side faces inland toward flat Midlands terrain with minimal visual interest during departure. Notable sights include: Thames estuary and London docks, Chiltern Hills escarpment, Greater London urban grid.

When landing at Chengdu Tianfu International Airport (TFU), sit on the Right side for the best views. Right side (south/southwest approach) reveals the Sichuan Basin's dramatic topography: the Longquan Mountains and Qinling foothills create visible ridgelines, and the Minjiang River valley system is traceable through the agricultural plains. Left side faces the flat northern basin with minimal terrain variation during descent. Notable sights include: Longquan Mountains ridgeline, Minjiang River valley, Chengdu's urban sprawl and surrounding agricultural grid, Qinling foothills on distant horizon.

The flight from Heathrow (LHR) to Chengdu Tianfu International Airport (TFU) takes 11h 35m.
