Sit on the Right side of the plane for the best views on flights from Chengdu to Seoul. Right-side seats provide superior scenery during the critical takeoff phase with the Qinling Mountains, while landing views are comparable on both sides. The dramatic mountain scenery on departure outweighs the coastal approach advantage.

During takeoff from Shuangliu (CTU), sit on the Right side for the best views. Right-side seats capture the Qinling Mountains immediately after departure as the aircraft climbs northeast. The range forms a dramatic natural barrier north of Chengdu and is clearly visible during the initial climb phase. Notable sights include: Qinling Mountains (northeast), Chengdu urban sprawl (directly below during initial climb), Min River valley (visible as it winds through the plain), Longquan Mountains (eastern horizon).

When landing at Incheon International (ICN), sit on the Left side for the best views. Left-side seats offer views of the Han River estuary and Incheon's coastal geography during descent. The river's wide mouth and the Yellow Sea coastline are prominent features on approach to ICN from the southwest. Notable sights include: Han River estuary (wide and clearly defined), Incheon waterfront and reclaimed land areas, Yellow Sea coastline, Seoul metropolitan area (visible inland to the southeast).

The flight from Shuangliu (CTU) to Incheon International (ICN) takes 3h 15m.

The flight path crosses the North China Plain after passing the Qinling Mountains, with the Yellow River visible in the middle section of the route. The Taihang Mountains form a secondary ridge line to the east. As the aircraft approaches the Korean Peninsula, the Taebaek Mountains become visible on the eastern coast of South Korea before descent into the Seoul basin.
