ICN → ULN
Which side of the plane to sit from Incheon International Airport (Seoul) to Chinggis Khaan International Airport (Ulan Bator)?
Right Side of the Plane
The right side offers the most dramatic transition from the mountainous Korean peninsula to the legendary vast green steppes and rugged Khentii Mountains of Mongolia.
Search flights from ICN to ULN
Liaoning Highlands
Rugged mountain ranges in Northeast China that offer beautiful textures, especially during winter snowfall.
Inner Mongolian Steppe
Endless, rolling green grasslands that look like a lush carpet, stretching toward the horizon.
Khentii Mountains
The forested mountain range that serves as the birthplace of Genghis Khan and hosts a diverse ecosystem.
Tuul River
A winding, silver river that snakes through the valley floor during the final approach into Ulan Bator.
The right side is premier for the final descent into ULN, as the plane often banks to align with the valley, offering panoramic views of the Mongolian plateau. In autumn, the grasslands turn a brilliant gold. For early morning flights, be prepared for some glare, but the light on the mountains is unmatched.

Incheon Bridge
A spectacular aerial view of the 21.38km bridge connecting Incheon International Airport to the mainland.
Yellow Sea Expanse
The vast maritime corridor between Korea and China, often filled with large cargo vessels and fishing fleets.
Gobi Desert Fringe
The southern horizon reveals the edges of the Gobi, showing a stark shift to arid, reddish-brown earth.
Ger Districts
The unique layout of Ulan Bator's outskirts, where traditional nomadic dwellings blend with urban expansion.
Choose the left side for morning flights to avoid the direct eastern sun. Watch for the dramatic change in soil color as you cross the Chinese-Mongolian border. The left side is generally better for seeing the industrial sprawl of Northern China before the Mongolian wilderness begins.
