Sit on the Right side of the plane for the best views on flights from Seattle to Kaohsiung. The right side wins overall due to the exceptional Mount Rainier view during takeoff, which is a guaranteed highlight. The landing approach offers less dramatic scenery on either side, so the strong takeoff advantage determines the overall recommendation.

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 heading southeast. The mountain is directly on the departure corridor and dominates the early ascent phase. Notable sights include: Mount Rainier (14,411 ft), Cascade Range, Puget Sound, Olympic Mountains to the west.

When landing at Kaohsiung International (KHH), sit on the Left side for the best views. Left-side seats offer views of the Taiwan Strait and the Taiwanese coastline as the aircraft descends toward Kaohsiung from the northwest. The approach path brings the western coast and harbor into clear view on the left side. Notable sights include: Taiwan Strait, Kaohsiung Harbor, Gaoping River delta, Kaohsiung city grid.

The flight from Seattle Tacoma International (SEA) to Kaohsiung International (KHH) takes Approximately 11-12 hours.

The flight path crosses the North Pacific, passing north of Hawaii (typically 200+ miles north, not visible). Notable waypoints include the Aleutian Islands region (far north of track), then the open Pacific. As the aircraft approaches Taiwan, it may pass near or over the Ryukyu Islands (southern Japan) depending on exact routing, though these are often 100+ miles north of the standard approach corridor. The most significant midpoint feature is simply the vast open Pacific Ocean with no visible landmarks for roughly 8-9 hours of flight time.
