Sit on the Right side of the plane for the best views on flights from Seoul to Singapore. Takeoff views from the right side are superior—the Yellow Sea and Seoul metropolitan area provide more dramatic and sustained visual interest than landing views. The landing approach into Seletar is shorter and lower-altitude, limiting the window view advantage.

During takeoff from Incheon International (ICN), sit on the Right side for the best views. Right-side seats capture the Yellow Sea and Seoul's urban sprawl during the initial climb. ICN typically departs runways 15L/15R or 33L/33R; northbound departures (15L/15R) offer the best westward view over water and the Korean peninsula's western coast. Notable sights include: Yellow Sea (immediate west), Seoul metropolitan area (southeast, visible as dense urban grid), Han River estuary (south), Incheon's industrial zones (south-southwest).

When landing at Seletar (XSP), sit on the Left side for the best views. Left-side seats provide views of Singapore's Strait of Johor and the Malaysian peninsula during descent. Seletar's runway 03/21 orientation means southbound approaches (runway 03) offer extended views of the strait and Malaysia's Johor state across the water before turning final. Notable sights include: Strait of Johor (north and west), Johor Bahru city (Malaysia, northwest), Singapore's northern reservoirs and greenery (south), causeway connecting Singapore to Malaysia (visible as thin line across strait).

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

The flight path crosses the South China Sea, passing west of the Philippines. Notable midpoint geography includes the Strait of Malacca region (visible during descent into Singapore), with Malaysia's Peninsular coast to the west and Sumatra's northern tip to the southwest. The flight transits through busy shipping lanes in the South China Sea and approaches Singapore from the north, crossing the Strait of Johor.
