Sit on the Right side of the plane for the best views on flights from Seoul to Houston. The right side wins overall because the departure from Incheon delivers genuinely dramatic and distinctive scenery — Seoul's Han River, the city grid, and the Korean coastal geography — which is more visually rewarding than either side on the Houston approach over flat Texas lowlands. Mid-flight over the North Pacific offers little from either side, so the departure experience tips the balance.

During takeoff from Incheon International (ICN), sit on the Right side for the best views. ICN departures on runway 15R/33L or 16/34 typically head northeast or south over the Yellow Sea. A right-side seat gives you views back over Seoul's Han River and the city sprawl as you climb out, while the left side faces open water early. Departing northbound, the right side catches the Seoul metropolitan area including the Han River bridges and Bukhansan ridgeline to the northeast. Notable sights include: Han River and its bridges through central Seoul, Bukhansan granite peaks northeast of the city, Incheon harbor and reclaimed land visible below during initial climb, Gyeonggi Bay coastal mudflats.

When landing at George Bush Intcntl Houston (IAH), sit on the Left side for the best views. IAH arrivals from the west or northwest typically use runways 26L/26R or 27, meaning the aircraft approaches from the east side of the airport. A left-side seat on approach from the northwest gives views over downtown Houston's skyline and the Ship Channel. The right side faces suburban sprawl with fewer distinctive features. Notable sights include: Downtown Houston skyline cluster, Houston Ship Channel and turning basin, Lake Houston to the northeast, Texas Gulf Coast lowland bayou network.

The flight from Incheon International (ICN) to George Bush Intcntl Houston (IAH) takes Approximately 13 to 14 hours.

The great circle route from ICN to IAH tracks northeast over the Sea of Japan, crosses the Aleutian Island chain of Alaska where volcanic peaks may be visible on clear days, then arcs southeast over the Gulf of Alaska and the Canadian Rockies in British Columbia and Alberta before descending over the central US plains through Oklahoma and into Texas. The Aleutian Islands and the snow-covered Canadian Rockies are the most visually significant features along the route, though both depend heavily on weather and daylight timing.
