Sit on the Right side of the plane for the best views on flights from Washington to Las Vegas. Right side wins both ends of the flight. During the cruise over the Southwest, the right side also offers better views of the Colorado Plateau canyon country and the Mojave desert terrain as the route tracks southwest, making it the clear choice for the full journey.

During takeoff from Washington Dulles International (IAD), sit on the Right side for the best views. Dulles typically departs westbound on runway 19R/01L or uses runways oriented northeast-southwest. On a westbound departure toward Las Vegas, a right-side seat gives you views south toward the DC metro area including the Potomac River and the broader Northern Virginia suburbs as you climb out and bank west. The left side faces north into less distinctive terrain. Notable sights include: Potomac River corridor, Blue Ridge Mountains to the west, Shenandoah Valley, Northern Virginia suburban sprawl.

When landing at Mc Carran International (LAS), sit on the Right side for the best views. Las Vegas McCarran typically lands from the north or northeast on runways 26L/26R or 19R, meaning the approach comes in over the desert from the northeast. A right-side seat on approach gives you a direct view of the Las Vegas Strip running north-south below and to your right, with the Spring Mountains and Red Rock Canyon visible to the west. Left side faces east toward open Mojave desert with less visual interest. Notable sights include: Las Vegas Strip, Spring Mountains and Red Rock Canyon escarpment, Lake Mead to the northeast, Hoover Dam.

The flight from Washington Dulles International (IAD) to Mc Carran International (LAS) takes Approximately 4 hours 30 minutes to 4 hours 50 minutes westbound.

The flight tracks roughly southwest over the Appalachians in West Virginia, then across Kentucky and Tennessee before crossing the Mississippi River near Memphis. It then crosses Arkansas and Oklahoma into the Texas Panhandle, over the Llano Estacado flatlands, before reaching New Mexico and the Colorado Plateau. The Four Corners region may be visible with its canyon systems, followed by the Kaibab Plateau north of the Grand Canyon, and finally the Mojave Desert into Las Vegas. The Grand Canyon's South Rim may be visible on the right side roughly 200 miles out from Las Vegas.
