Sit on the Left side of the plane for the best views on flights from Bangkok to Seoul East. While takeoff favors the right for delta views, the landing approach offers superior geography—the Han River and Seoul's urban landscape are more visually distinctive than Bangkok's departure. The left side captures the flight's destination geography more memorably.

During takeoff from Bangkok International (BKK), sit on the Right side for the best views. BKK typically departs eastbound (runways 01L/01R). Right-side seats offer views of the Chao Phraya River delta and the Gulf of Thailand as you climb out over the coastal plain. Left side faces inland toward the city and loses the water views quickly. Notable sights include: Chao Phraya River delta with its intricate waterway network, Gulf of Thailand coastline, Bangkok metropolitan sprawl extending inland, Don Mueang Airport visible to the north.

When landing at Seoul Ab (SSN), sit on the Left side for the best views. Incheon/Seoul approach typically uses westbound runways (15L/15R). Left-side seats during descent offer views of the Han River as it winds through Seoul, the city's districts, and the surrounding mountains. Right side faces away from the city center toward less distinctive terrain. Notable sights include: Han River (Hangang) flowing through Seoul with its distinctive bends, Seoul's urban districts and high-rise clusters, Bukhansan and surrounding northern mountain ranges, Incheon's industrial areas and reclaimed land to the west.

The flight from Bangkok International (BKK) to Seoul Ab (SSN) takes Approximately 4 hours 45 minutes to 5 hours 15 minutes.

The flight path crosses the Gulf of Thailand, then over central Thailand (Nakhon Ratchasima plateau visible as terrain rises inland), continues northeast over Laos and into northern Thailand/Laos border region, then crosses into Vietnam airspace before turning north toward China and finally northeast into Korean airspace. The Mekong River valley and the transition from Southeast Asian lowlands to higher terrain in northern regions are the primary geographic features along the route. Visibility of these features depends on altitude, weather, and time of day—typically the route cruises at 35,000+ feet where individual rivers are difficult to distinguish, but major terrain changes and weather systems are visible.
