Sit on the Left side of the plane for the best views on flights from Bangkok to Houston. Left side wins both ends of this flight. Bangkok's Chao Phraya River and city core on departure, and Houston's downtown skyline on approach are both on the left. The transpacific routing over the Pacific offers little to see at cruise altitude regardless of side, so the departure and arrival views are the deciding factor.

During takeoff from Bangkok International (BKK), sit on the Left side for the best views. Suvarnabhumi typically departs northward on runway 19L/01R or eastward on 01L/19R. On a northbound departure climbing out, the left side gives you Bangkok's urban core — the Chao Phraya River bends, the dense grid of the city center, and the glittering temple rooftops of the old city district. The right side faces east toward flat agricultural plains with little visual interest. Notable sights include: Chao Phraya River meanders through central Bangkok, Grand Palace and Wat Phra Kaew temple complex, Bangkok's dense urban grid fading into suburban sprawl, Gulf of Thailand visible to the south as you climb.

When landing at George Bush Intcntl Houston (IAH), sit on the Left side for the best views. IAH typically lands from the southeast on runways oriented roughly 15/33. On approach from the southeast, the left side faces northeast toward downtown Houston's skyline, which becomes clearly visible during the final 20-30 miles of approach. The right side faces southwest over flat suburban sprawl with no distinguishing features. Notable sights include: Downtown Houston skyline cluster visible to the northeast, Buffalo Bayou corridor threading through the urban area, Houston Ship Channel and industrial port complex to the east, flat Texas coastal plain grid of highways and subdivisions.

The flight from Bangkok International (BKK) to George Bush Intcntl Houston (IAH) takes Approximately 17-18 hours nonstop, typically routing via a polar-adjacent transpacific great circle track.

The flight tracks northeast from Bangkok over southern China and the East China Sea, crosses Japan's southern islands near Okinawa, then arcs across the North Pacific over open ocean for the bulk of the flight. The Aleutian Islands chain may be visible in the far distance depending on exact routing. The flight descends over the US Pacific coast near California or Oregon before crossing the Sierra Nevada, the Mojave Desert, and the vast flat plains of Texas on the final approach to Houston.
