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.

Flight Path
Seattle to Kaohsiung is 6,234 miles (10,033 km), a flight of about 11 hours 30 minutes.
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.
