Sit on the Left side of the plane for the best views on flights from Hakodate to Seoul. While takeoff offers dramatic volcanic and strait views from the right, the landing approach provides sustained views of Incheon's engineered landscape and the Yellow Sea corridor—more visually distinctive than the flight's midpoint. Left seats capture the approach's most photogenic elements.

During takeoff from Hakodate (HKD), sit on the Right side for the best views. Hakodate typically departs runway 16 (southbound). Right-side seats face west across Tsugaru Strait toward Aomori Prefecture, offering views of the strait's width and the Oshima Peninsula's volcanic cone. Left seats look inland over forested terrain with minimal visual interest. Notable sights include: Oshima volcano (Hokkaido side, distinctive conical peak), Tsugaru Strait (wide water body separating Hokkaido from Honshu), Aomori Prefecture coastline (distant, northern shore), Hakodate Bay (visible during initial climb).

When landing at Incheon International (ICN), sit on the Left side for the best views. Incheon typically uses runways 03L/03R (northbound approach) or 15L/15R (southbound). On northbound approaches (more common), left-side seats face west across the Yellow Sea toward China, with views of Incheon's reclaimed land islands and the airport's distinctive artificial peninsula. Right seats face the Korean mainland interior. Notable sights include: Incheon International Airport's artificial islands and causeway (massive reclaimed land structures), Yellow Sea (western approach corridor), Ganghwa Island (large island visible to the northwest), Seoul metropolitan area (distant inland, visible as urban haze).

The flight from Hakodate (HKD) to Incheon International (ICN) takes Approximately 1 hour 45 minutes.

The flight crosses the Yellow Sea at roughly 25,000-30,000 feet. The midpoint (around 52 minutes) occurs over open water northwest of South Korea's west coast. No major islands are directly on the standard flight path, though Ganghwa Island lies to the north. The Korean peninsula's western coastline becomes visible as the aircraft descends toward Incheon, with the Gyeonggi Bay area and reclaimed tidal flats appearing as tan-colored geometric patterns. Weather systems moving east from China frequently create cloud layers at 10,000-15,000 feet along this corridor.
