Sit on the Left side of the plane for the best views on flights from Singapore to Seoul. While takeoff favors the right for Strait of Malacca views, the landing approach on the left provides more dramatic and visually distinctive scenery with the Han River estuary, Seoul's urban landscape, and surrounding mountains. The landing experience outweighs the takeoff advantage.

During takeoff from Seletar (XSP), sit on the Right side for the best views. Right side offers views of the Strait of Malacca and Malaysian peninsula as the aircraft climbs northwestward. Left side faces the densely built-up Singapore urban area with limited scenic variation. Notable sights include: Strait of Malacca, Johor Bahru cityscape, Malaysian peninsula coastline, Singapore's northern water catchment reservoirs.

When landing at Incheon International (ICN), sit on the Left side for the best views. Left side provides views of the Han River estuary, Seoul's urban sprawl, and the surrounding mountainous terrain as the aircraft descends toward Incheon. Right side faces the Yellow Sea with less distinctive features. Notable sights include: Han River estuary, Seoul metropolitan area, Gyeonggi Province mountains, Incheon waterfront.

The flight from Seletar (XSP) to Incheon International (ICN) takes Approximately 4 hours 45 minutes to 5 hours 15 minutes.

The flight path crosses the South China Sea heading northeast, passing over or near the Hainan Island region (visible as a large landmass if flying slightly west of direct route), then transitions over the East China Sea. The Yellow Sea crossing offers limited distinctive features—primarily open water. As the aircraft approaches Korean airspace, the Korean peninsula becomes visible with its mountainous spine (Taebaek Mountains) running north-south along the eastern side. The flight typically descends over the Yellow Sea west of the peninsula before turning toward Incheon's approach corridor.
