Sit on the Left side of the plane for the best views on flights from Seoul to Seattle. While takeoff offers better initial views from the right, the landing approach from the left provides more dramatic and iconic scenery—Puget Sound, the Olympic Mountains, and Seattle's recognizable landmarks. The landing experience outweighs the takeoff advantage.

During takeoff from Incheon International (ICN), sit on the Right side for the best views. ICN typically departs to the west or southwest over the Yellow Sea. Right-side seats offer unobstructed views of Seoul's urban sprawl and the coastal geography as the aircraft climbs. Left seats face inland toward mountains with less dramatic visual interest during initial climb. Notable sights include: Seoul metropolitan area (sprawling urban grid), Yellow Sea (Hwanghae), Incheon harbor and industrial zones, Han River estuary.

When landing at Boeing Fld King Co International (BFI), sit on the Left side for the best views. BFI sits on the east bank of the Duwamish River in south Seattle. Approaching from the west (typical for transpacific arrivals), left-side seats provide excellent views of Puget Sound, the Olympic Mountains, and the Seattle skyline during descent. Right seats face inland toward less distinctive terrain. Notable sights include: Puget Sound (body of water), Olympic Mountains (western horizon), Seattle downtown skyline and Space Needle, Duwamish River and industrial waterfront.

The flight from Incheon International (ICN) to Boeing Fld King Co International (BFI) takes Approximately 10.5 to 11.5 hours.

The flight path crosses the Korean Peninsula (mountains visible during initial climb), then the Yellow Sea, then the vast Pacific Ocean for roughly 8 hours with no significant landmarks. As the aircraft approaches North America, the Aleutian Islands may be visible in far northern latitudes depending on routing, followed by the British Columbia coast and Cascade Range as the aircraft descends toward Seattle.
