Sit on the Left side of the plane for the best views on flights from Singapore to Seoul. While takeoff favors the right for water views, the landing approach on the left provides more dramatic and sustained views of Seoul's geography, the Han River system, and the approach corridor into Gimpo. The left side captures the more visually interesting portion of the descent.

During takeoff from Seletar (XSP), sit on the Right side for the best views. Seletar typically departs runway 03 (northeast) or 21 (southwest). Right-side seats offer views of the Strait of Johor and Malaysia's Johor state during initial climb, with the industrial landscape of northern Singapore visible on the left. The right side captures the water crossing and Malaysian coastline more prominently. Notable sights include: Strait of Johor, Johor Bahru city (Malaysia), Bukit Timah area (Singapore), Causeway bridge infrastructure.

When landing at Gimpo (GMP), sit on the Left side for the best views. Gimpo typically uses runways 14 or 32. Approaching from the south, left-side seats provide views of the Han River valley, Seoul's western districts, and the Gimpo area itself. The left side captures the river system and urban sprawl of Seoul more effectively than the right, which faces toward Incheon. Notable sights include: Han River (Hangang), Seoul metropolitan area, Gimpo industrial zone, Bukhan Mountains (distant north).

The flight from Seletar (XSP) to Gimpo (GMP) takes Approximately 5 hours 45 minutes to 6 hours 15 minutes.

The flight path crosses the South China Sea, passes near or over Hainan Island (depending on routing), then transitions over mainland China toward the Korean Peninsula. Notable midpoint features include the Hainan coastline (if visible), the Chinese mainland's eastern provinces with their river systems, and eventually the Yellow Sea (West Sea) before approaching Korean airspace. The Taishan and Wuyi mountain ranges may be visible as distant ridges if flying over central China. Most of the midpoint flight occurs over open water or haze-obscured terrain at cruise altitude.
