Sit on the Left side of the plane for the best views on flights from Tokyo to Bangkok. Left side wins at both ends of the flight. During the cruise over the South China Sea and Indochina, the left side also picks up the Vietnamese coastline and the Gulf of Tonkin as the route tracks southwest, making it the stronger choice throughout.

During takeoff from Tokyo International (HND), sit on the Left side for the best views. HND typically departs southward on Runway 34L/34R or westward on Runway 16R. A left-side seat gives you Tokyo Bay sweeping out ahead, with the dense urban grid of central Tokyo and the Yokohama waterfront visible to the northeast. As the aircraft banks southwest toward the flight path, Mount Fuji appears on the left horizon on clear days. Notable sights include: Tokyo Bay, Yokohama port and waterfront, Mount Fuji (on clear days to the west-southwest), central Tokyo urban grid.

When landing at Bangkok International (BKK), sit on the Left side for the best views. Suvarnabhumi (BKK) typically lands on runways oriented roughly east-west (Runway 19L/19R or 01L/01R). On approach from the north, a left-side seat looks east over the Gulf of Thailand coastline and the flat Chao Phraya delta. The city of Bangkok and the Chao Phraya River snaking through it are visible to the left as the aircraft descends over the central plains. Notable sights include: Chao Phraya River delta, Gulf of Thailand coastline, Bangkok urban core, flat central Thai plains.

The flight from Tokyo International (HND) to Bangkok International (BKK) takes Approximately 6 to 6.5 hours.

The route tracks southwest over the East China Sea, passing near Taiwan and the northern Philippines, then crosses the South China Sea. Over Indochina the aircraft passes over southern Vietnam and Cambodia before descending into Bangkok. The South China Sea dominates the mid-flight view, with occasional glimpses of the Vietnamese coastline and the Mekong Delta on the left side as the route approaches Thailand.
