Sit on the Right side of the plane for the best views on flights from Taipei to Seoul. Right-side seats capture the most geographically significant views: the Taiwan Strait and northern Taiwan during departure, then the flight path across open water before approaching Seoul's western geography on descent. Left seats miss the strait entirely on takeoff and only gain advantage during the final approach phase.

During takeoff from Chiang Kai Shek International (TPE), sit on the Right side for the best views. TPE typically departs runway 05L/05R (northeast heading). Right-side seats face the Taiwan Strait and northern Taiwan's coastline during initial climb, offering clear views of the strait's geography before the aircraft turns northward. Notable sights include: Taiwan Strait (immediate foreground), northern Taiwan coastline including Keelung area, Yangmingshan volcanic plateau to the east, Taipei basin urban sprawl.

When landing at Gimpo (GMP), sit on the Left side for the best views. GMP (Gimpo) typically uses runways 14L/14R for landing (northeast approach). Left-side seats face west and southwest during descent, providing views of Seoul's western districts, the Han River, and Incheon's industrial areas before touchdown. Notable sights include: Han River (Hangang) winding through Seoul, Seoul's western districts (Mapo, Yeongdeungpo), Incheon industrial zone and port facilities, Gimpo Airport's immediate surroundings.

The flight from Chiang Kai Shek International (TPE) to Gimpo (GMP) takes Approximately 2 hours 45 minutes to 3 hours 15 minutes.

The flight crosses the Taiwan Strait (approximately 100 nautical miles of open water), then passes over the Yellow Sea. At cruise altitude (typically 33,000-35,000 feet), the midpoint offers views of the Korean Peninsula's western coast approaching from the south, with Jeolla Province's coastal plains and river deltas becoming visible approximately 45 minutes before landing at GMP. The flight path generally follows a great circle route slightly west of due north.
