Seoul to Seattle flight path: ICN to SEA

Sit on the Left side of the plane for the best views on flights from Seoul to Seattle. While Seoul's skyline gives the right side a strong start, the left side carries the more dramatic cruise-phase terrain over Siberia's Kamchatka volcanoes and delivers the flight's most iconic single view — Mount Rainier and the Cascades — during the Seattle approach.

During takeoff from Incheon International (ICN), sit on the Right side for the best views. Departing ICN, the aircraft typically climbs out over the Yellow Sea's tidal mudflats and coastal islands before banking to join its northeasterly track, swinging Seoul's skyline and the Han River into view on the right side. Notable sights include: Incheon Bridge, Yellow Sea tidal flats and Ganghwa-do island, Seoul skyline with Lotte World Tower, Han River.

When landing at Seattle Tacoma International (SEA), sit on the Left side for the best views. On approach to Sea-Tac from the north down Puget Sound, the aircraft's final turn to land southbound puts the Cascade Range and Mount Rainier's unmistakable snow-capped cone on the left, along with Lake Washington and Seattle's Eastside. Notable sights include: Mount Rainier, Cascade Range foothills, Lake Washington, Seattle's Eastside suburbs.

The flight from Incheon International (ICN) to Seattle Tacoma International (SEA) takes about 10 hours 5 minutes. The shortest flight path between them is 5,203 miles (8,373 km); winds and air traffic control usually add a few percent.

The route's midpoint lies over the Sea of Okhotsk and the volcanic spine of Russia's Kamchatka Peninsula, with the open Bering Sea and Aleutian chain beyond before the track curves southeast toward Alaska and British Columbia.
