Sit on the Right side of the plane for the best views on flights from Ulaanbaatar (Sergelen) to Seoul. Right-side seats capture the most dramatic scenery: the Khentii Mountains and Tuul River during departure, followed by the transition across Mongolia's steppe, and then views of the Korean peninsula's western mountains and river systems during descent. Left seats offer strong landing views but miss the compelling Mongolian geography at takeoff.

During takeoff from Ulaanbaatar Chinggis Khaan International Airport (UBN), sit on the Right side for the best views. Right-side seats offer views of the Khentii Mountains and the Tuul River valley as the aircraft climbs southeastward from Ulaanbaatar. The terrain transitions from urban sprawl to rolling steppe with visible river systems. Notable sights include: Khentii Mountains (southeast), Tuul River valley, Ulaanbaatar city grid (receding northward), steppe grasslands extending to the horizon.

When landing at Incheon International (ICN), sit on the Left side for the best views. Left-side seats provide excellent views of the Han River estuary, Incheon's tidal flats, and the approach over the Yellow Sea. As the aircraft descends toward Incheon, the left wing reveals the complex waterway system and coastal geography that defines the Seoul metropolitan area's western boundary. Notable sights include: Han River estuary and delta, Incheon tidal mudflats, Yellow Sea coastline, Gyeonggi Bay.

The flight from Ulaanbaatar Chinggis Khaan International Airport (UBN) to Incheon International (ICN) takes Approximately 2 hours 15 minutes.

The flight path crosses central Mongolia's steppe plateau (relatively featureless at altitude), then transitions over the Yalu River region and Korean peninsula's western mountains. The Taedong River valley near Pyongyang may be visible in clear conditions, though this is near the flight path's eastern edge. Most of the midpoint consists of open steppe and low mountain ranges with minimal distinctive landmarks visible from cruising altitude.
