Sit on the Right side of the plane for the best views on flights from Taipei to Cheju. Right-side seats provide superior views for both segments: the Taiwan Strait and northern Taiwan during departure, plus unobstructed views of the Korea Strait and Jeju Island's volcanic landscape during approach. The northbound flight path naturally favors the right side for most of the journey.

During takeoff from Chiang Kai Shek International (TPE), sit on the Right side for the best views. Right-side seats capture the northbound climb-out over the Taiwan Strait with views of northern Taiwan's coastline and the Central Mountain Range receding behind. Left seats face inland toward the island's interior. Notable sights include: Taiwan Strait (east-west water body), Central Mountain Range (north-south spine visible as elevation), Taipei basin and urban sprawl, northern Taiwan coastline near Keelung.

When landing at Jeju International (CJU), sit on the Left side for the best views. Left-side seats offer the best views during the standard southwesterly approach into Jeju, with views of Jeju Island's volcanic landscape, the southern Korean coast, and the Korea Strait. Right seats face away from the island during final approach. Notable sights include: Jeju Island (volcanic island with Hallasan mountain visible as central peak), Korea Strait (water body to the south and west), southern Korean mainland coastline, Jeju's distinctive black lava fields and coastal cliffs.

The flight from Chiang Kai Shek International (TPE) to Jeju International (CJU) takes Approximately 2 hours 15 minutes.

Taiwan Strait (entire crossing, roughly 100 nautical miles of open water), transition zone over the Korea Strait with scattered islands visible, approach to South Korean airspace with the southern Korean peninsula and coastal features becoming visible in the final 30 minutes
