Sit on the Right side of the plane for the best views on flights from Seoul to Las Vegas. Right side wins both the departure over Seoul and the arrival into Las Vegas. Over the Pacific and Alaska the views are largely ocean and cloud regardless of side, so the bookend city views are the deciding factor and both favor the right seat.

During takeoff from Incheon International (ICN), sit on the Right side for the best views. Incheon departures heading northeast or east typically use runways oriented roughly 15/33 or 33L/33R. A right-side seat gives you views over Seoul's Han River, the dense urban grid of the city, and Namsan hill with N Seoul Tower as you climb out eastward. The left side faces the Yellow Sea and open water almost immediately. Notable sights include: Han River and its bridges through central Seoul, Namsan hill and N Seoul Tower, the dense Gangnam district grid, Bukhansan mountain ridgeline north of the city.

When landing at Mc Carran International (LAS), sit on the Right side for the best views. Las Vegas arrivals from the west or northwest typically land on runways 26L/26R or 19L/19R. On approach from the northwest descending over the Las Vegas Valley, the right side gives you the Strip's hotel towers, Fremont Street area, and the surrounding Mojave basin. The left side faces the Spring Mountains and Red Rock Canyon escarpment, which is also scenic but the Strip is the signature view. Notable sights include: Las Vegas Strip hotel towers, Fremont Street downtown cluster, Lake Mead to the east on the horizon, Spring Mountains (Charleston Peak) to the west.

The flight from Incheon International (ICN) to Mc Carran International (LAS) takes Approximately 11 to 12 hours.

The great circle route from ICN to LAS arcs northeast over the Sea of Japan, crosses the southern tip of the Kamchatka Peninsula and the Aleutian Island chain, then tracks across the Gulf of Alaska and the Canadian Rockies in British Columbia and Alberta before descending over the Great Basin of Nevada. Passengers may see the Aleutian volcanic peaks on clear days, the snow-covered Canadian Rockies as a dramatic corrugated white ridgeline, and the vast high desert basin-and-range terrain of Nevada on descent.
