Sit on the Left side of the plane for the best views on flights from Cheju to Tokyo. Left side wins both ends of the flight. At departure you get Hallasan and Jeju's volcanic landscape; during the cruise you track northeast over the Korea Strait and the southern tip of Honshu; on approach you face central Tokyo rather than open bay. The left seat is the clear choice for the full journey.

During takeoff from Jeju International (CJU), sit on the Left side for the best views. Jeju departs northeast toward Japan, typically using runway 07 or 25. A left/north-facing seat gives you a clear view of Hallasan, Jeju's central shield volcano rising to 1,950m, as the aircraft climbs and banks northeast. You'll also see the rugged northern coastline and the open Korea Strait ahead. Notable sights include: Hallasan volcano (central Jeju), Jeju northern coastline, Jeju City urban grid, Korea Strait opening to the north.

When landing at Tokyo International (HND), sit on the Left side for the best views. Haneda typically lands from the east or southeast on runways 34L/34R or 22, with the approach over Tokyo Bay. A left seat faces west toward central Tokyo, giving you the city skyline, Tokyo Tower, and the dense urban grid of Shinagawa and Shibuya as you descend over the bay. The right side faces mostly open bay water. Notable sights include: Tokyo Bay approach, central Tokyo skyline, Tokyo Tower, Yokohama waterfront to the southwest.

The flight from Jeju International (CJU) to Tokyo International (HND) takes Approximately 1 hour 30 minutes.

Korea Strait crossing (roughly 200km of open water), southern tip of the Korean Peninsula near Busan visible to the northwest early in flight, Tsushima Island (Japan) as a distinct forested landmass in the strait, Iki Island further northeast, then the northwestern coastline of Kyushu near Fukuoka, followed by the Seto Inland Sea and the mountainous spine of western Honshu before descending toward Tokyo Bay
