Sit on the Left side of the plane for the best views on flights from Chicago to Bangkok. Takeoff from Chicago over Lake Michigan provides more dramatic and immediate visual interest than landing approach. While Bangkok's delta is visually rich, the Lake Michigan departure offers clearer, more distinctive urban and water features during the initial climb phase when passengers are most engaged.

During takeoff from Chicago Ohare International (ORD), sit on the Left side for the best views. Left side offers views of Lake Michigan immediately after departure, with the Chicago skyline receding behind. Right side faces inland toward flat terrain with minimal visual interest during climb-out. Notable sights include: Lake Michigan, Chicago downtown skyline, Indiana shoreline to the south.

When landing at Bangkok International (BKK), sit on the Right side for the best views. Right side provides views of the Chao Phraya River delta and Bangkok's sprawling urban landscape as the aircraft descends toward Suvarnabhumi. Left side faces agricultural plains with less distinctive features during final approach. Notable sights include: Chao Phraya River delta and meanders, Bangkok metropolitan area, rice paddies and irrigation canals of central Thailand.

The flight from Chicago Ohare International (ORD) to Bangkok International (BKK) takes 15h 20m.

The flight path crosses the North American continent (Great Lakes, Rocky Mountains visible from altitude), then the Arctic/subarctic regions with minimal landmarks, before descending over Russia's Far East, then across China and Southeast Asia. Notable features include: the Canadian Shield terrain, the Rocky Mountains (particularly visible if routing south of direct great circle), the Bering Strait region, Siberian tundra and taiga, and eventually the Himalayan foothills and Indochinese Peninsula as approach to Thailand begins.
