Sit on the Right side of the plane for the best views on flights from Bangkok to Los Angeles. The right side wins overall. While left is better at takeoff for Bangkok city views, the right side delivers the more dramatic arrival sequence over the Santa Monica Mountains and Los Angeles Basin, which is the more memorable visual payoff. On the long transpacific cruise, neither side has a meaningful advantage, but right-side passengers also get better views of the Japanese coastline and Aleutian Islands arc during the northern Pacific routing.

During takeoff from Bangkok International (BKK), sit on the Left side for the best views. Suvarnabhumi typically departs northeast on runway 01L/01R or east on 19R/19L depending on wind. On the dominant northward departure, the left side faces west over central Bangkok, giving a clear view of the Chao Phraya River snaking through the city grid and the dense urban core. The right side faces east toward flat agricultural plains with little of interest. Notable sights include: Chao Phraya River bends through central Bangkok, Grand Palace district near the river's west bank, Bangkok urban grid extending to the horizon, Bang Pakong River delta to the southeast.

When landing at Los Angeles International (LAX), sit on the Right side for the best views. LAX approaches typically come in from the east or northeast over the Los Angeles Basin on runways 24L/24R heading west. The right side faces north, giving views over the Santa Monica Mountains, the San Fernando Valley, and the Hollywood Hills as the aircraft descends. The left side faces south over the South Bay and suburban sprawl with less topographic interest. Notable sights include: Santa Monica Mountains running east-west across the northern view, San Fernando Valley floor visible beyond the mountains, Hollywood Hills and Griffith Park area, Santa Monica Bay coastline approaching from the right.

The flight from Bangkok International (BKK) to Los Angeles International (LAX) takes Approximately 17 to 18 hours nonstop.

The route tracks northeast over the South China Sea, then across southern Japan and the Japanese archipelago including Kyushu and Honshu, before heading out over the North Pacific on a great circle arc passing south of the Aleutian Islands chain. The Aleutians may be visible as a string of volcanic islands on the horizon during the northern Pacific segment. The route then descends over the Pacific toward the California coast, crossing the coastline north of Los Angeles before turning south for the LAX approach.
