Sit on the Left side of the plane for the best views on flights from Seoul to Washington. While takeoff offers good coastal views on the right, the landing approach into DCA on the left provides the most iconic and memorable sights—the Potomac River and DC monuments are far more visually distinctive than anything visible during the long Pacific crossing. The left side captures the approach's defining geography.

During takeoff from Incheon International (ICN), sit on the Right side for the best views. ICN typically departs to the west or southwest. Right-side seats offer views of the Yellow Sea coastline and the Korean peninsula's western edge as you climb out. Left seats face inland toward Seoul and the mountains, which are less distinctive during initial climb. Notable sights include: Yellow Sea (immediate water body west of airport), Incheon's industrial port facilities along the coast, Gyeonggi Bay to the southwest, distant Taebaek Mountains to the east appearing as a low ridge on the horizon.

When landing at Ronald Reagan Washington National (DCA), sit on the Left side for the best views. DCA approaches from the east over the Potomac River valley. Left-side seats provide direct views of the Potomac River, Arlington, and the Washington Monument/Capitol area as you descend into the final approach corridor. Right seats face Virginia's suburbs and lack the iconic landmarks. Notable sights include: Potomac River (primary visual reference for approach), Washington Monument and Capitol Building (visible in clear conditions from 3,000-5,000 ft on final approach), Arlington National Cemetery, Theodore Roosevelt Island.

The flight from Incheon International (ICN) to Ronald Reagan Washington National (DCA) takes Approximately 13-14 hours (great circle route crossing the Pacific, typically via Alaska airspace).

Aleutian Islands and Bering Sea (visible on northbound routing), Alaska's Aleutian chain appears as dark volcanic peaks on the horizon during mid-Pacific cruise, North American coastline near British Columbia or Alaska (depending on exact routing), Canadian Rockies visible on approach to North America, Great Lakes region (if routed south of typical polar track), Appalachian Mountains visible during descent into Washington DC airspace
