Sit on the Left side of the plane for the best views on flights from Seoul to Taipei. While takeoff favors right seats for the Yellow Sea and Korean islands, landing provides superior views of Taiwan's geography, urban landscape, and the approach corridor. The landing sequence offers more sustained, detailed visibility of significant landmarks.

During takeoff from Incheon International (ICN), sit on the Right side for the best views. Incheon typically departs eastbound (runways 16L/16R or 34L/34R depending on wind). Right-side seats face south toward the Yellow Sea initially, then bank southeast over water with views of the Korean peninsula's western coastline and islands. Left seats see only inland terrain and urban sprawl. Notable sights include: Yellow Sea (immediate foreground), Ganghwa Island and smaller archipelago (mid-distance right), Korean peninsula's west coast receding southward, Incheon city grid visible briefly before climbing over water.

When landing at Chiang Kai Shek International (TPE), sit on the Left side for the best views. Taipei Taoyuan typically lands westbound (runways 05L/05R). Left-side seats descend over the Taiwan Strait with views of Taiwan's northern coast, the Taipei Basin, and the Keelung River valley. Right seats see only ocean and distant mainland China across the strait. Notable sights include: Taiwan Strait (mid-distance left), Keelung city and harbor (left, closer during descent), Taipei Basin with urban grid (left-center), Yangmingshan volcanic plateau (left background, appearing as elevated terrain).

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

The flight path crosses the Taiwan Strait at roughly 26°N latitude. Mid-flight offers views of the strait's open water, with the Chinese mainland visible as a distant landmass on the left (west) side at altitude, and Taiwan's northern tip and east coast appearing on the right (east) side. The Penghu Islands (Pescadores) may be visible as small specks in the strait's center during clear conditions. No major mountain ranges are visible at cruise altitude from this route, though the distant Central Mountain Range of Taiwan appears as a low ridge on the eastern horizon during descent.
