Seoul to Hanoi flight path: ICN to HAN

Sit on the Right side of the plane for the best views on flights from Seoul to Hanoi. The right side captures Seoul's skyline on departure, glimpses of southern China's karst terrain during cruise, and the Red River Delta on arrival, giving it far more visual variety than the left side's largely open-water and flat-plain views.

During takeoff from Incheon International (ICN), sit on the Right side for the best views. Departing ICN's 15/16 runways, the initial climb and southbound turn put Seoul's sprawling skyline, the Han River, and the hills ringing the city on the right side before the aircraft bends southwest toward China. The left side mostly shows open Yellow Sea and scattered islands. Notable sights include: Incheon Bridge and Yeongjong Island coastline, Seoul metropolitan skyline, Han River, low hills of Gyeonggi province.

When landing at Noibai International (HAN), sit on the Right side for the best views. On approach into Hanoi, the aircraft typically tracks over the Red River Delta before turning onto final, giving right-side passengers views of the braided river, patchwork rice paddies, and the city's outskirts. The left side during this phase mostly shows flat delta farmland with less definition. Notable sights include: Red River (Song Hong) delta channels, patchwork rice paddies, Hanoi's outer districts, distant Ba Vi highlands.

The flight from Incheon International (ICN) to Noibai International (HAN) takes about 3 hours 50 minutes. The shortest flight path between them is 1,668 miles (2,684 km); winds and air traffic control usually add a few percent.

East China Sea crossing near the Shandong Peninsula, followed by the hilly terrain of Guangxi province including the karst topography near Guilin and Nanning before the route crosses into northern Vietnam's mountains.
