Sit on the Right side of the plane for the best views on flights from Seattle to Seoul. Right-side seats deliver superior scenery on departure with Mount Rainier and the Cascades, and remain competitive on arrival with views of the Korean peninsula's western approach. Left seats excel only during landing; right seats offer more consistent visual interest across the full journey.

During takeoff from Seattle Tacoma International (SEA), sit on the Right side for the best views. Right-side seats capture the Cascade Range and Mount Rainier during the initial climb-out. SEA's standard departure routes head east or northeast, placing these dramatic peaks directly on the right wing within the first 15–20 minutes of flight. Notable sights include: Mount Rainier (14,411 ft), Cascade Range, Lake Union, Puget Sound.

When landing at Gimpo (GMP), sit on the Left side for the best views. Left-side seats offer views of Seoul's urban sprawl and the Han River during descent into Gimpo. Typical approach vectors from the northwest place the city and river system directly on the left wing during the final 20–30 minutes of descent. Notable sights include: Han River, Seoul metropolitan area, Gimpo Airport, Korean peninsula coastline.

The flight from Seattle Tacoma International (SEA) to Gimpo (GMP) takes 10h 25m.
