Sit on the Right side of the plane for the best views on flights from Hong Kong to Ulan Bator. While takeoff offers better views from the left, the landing approach from the right provides more dramatic and sustained visibility of Mongolia's distinctive geography—the river valley, mountain foothills, and vast steppe—which is the more memorable portion of this route.

During takeoff from Hong Kong International (HKG), sit on the Left side for the best views. HKG typically departs runway 07L/R heading northwest. Left seats offer views of Victoria Harbour and Kowloon Peninsula as you climb out over Hong Kong Island, with the urban landscape and water features dominating the initial climb. Notable sights include: Victoria Harbour, Kowloon Peninsula, Hong Kong Island skyline, New Territories extending northward.

When landing at Buyant Ukhaa (ULN), sit on the Right side for the best views. Approaching ULN from the south typically uses runway 26 (heading northwest). Right-side seats provide views of the Tuul River valley and the approach path over the Khangai Mountains' eastern foothills, with the Mongolian steppe landscape visible during descent. Notable sights include: Tuul River valley, Khangai Mountains (eastern slopes), Ulan Bator city sprawl, surrounding steppe grassland.

The flight from Hong Kong International (HKG) to Buyant Ukhaa (ULN) takes Approximately 3 hours 45 minutes to 4 hours 15 minutes.

The flight path crosses the South China Sea heading northwest, then over southern China (Guangdong/Guangxi provinces), transitioning into the Yangtze River valley region. The aircraft then continues northwest over central China, passing east of the Qinling Mountains. As you approach Mongolia, you'll cross into the Inner Mongolia Autonomous Region with increasingly sparse vegetation and open steppe landscape. The Khangai Mountains become visible on the right side during the final descent approach to Ulan Bator.
