Sit on the Right side of the plane for the best views on flights from Seoul to Osaka. Right-side seats dominate this route: excellent departure views of the Yellow Sea and Korean coast, and the flight path itself crosses the Korea Strait with the best water and island views on the right. Landing favors left, but the longer departure and midpoint segments favor right.

During takeoff from Incheon International (ICN), sit on the Right side for the best views. Right-side seats capture the Yellow Sea and the Korean peninsula's western coastline during the initial climb. ICN typically departs runways 03L/03R or 15L/15R depending on wind; either direction favors the right side for water and coastal geography. Notable sights include: Yellow Sea (immediate right), Incheon's reclaimed land and port facilities, Han River estuary to the southeast, Seoul metropolitan area visible inland.

When landing at Osaka International (ITM), sit on the Left side for the best views. Left-side seats offer the best approach views into ITM. Osaka International uses runways 14/32; standard approaches from the west pass over Osaka Bay and the city's eastern districts, placing the bay and urban landscape on the left during descent. Notable sights include: Osaka Bay (left side during approach), Kobe visible to the northwest across the bay, Osaka's urban grid and Dotonbori district, Ikoma Mountains to the east.

The flight from Incheon International (ICN) to Osaka International (ITM) takes Approximately 2 hours 15 minutes.

Korea Strait crossing (the narrow water passage between South Korea and Japan's Kyushu region), Tsushima Island visible as a landmass in the strait, transition from Korean airspace to Japanese airspace, approach to Kyushu's northern coast with Fukuoka region visible to the south, then the flight path turns southeast toward Osaka Bay
