Sit on the Right side of the plane for the best views on flights from Cincinnati to Las Vegas. The right side wins overall because the Las Vegas Strip arrival view on the right is one of the most dramatic urban aerial approaches in the US, and the right side also captures the Colorado Plateau canyon country and the Mojave Desert transition during cruise. The Cincinnati departure view on the left is good but shorter-lived. Right-side passengers also get glimpses of the Grand Canyon's South Rim if the routing goes near Flagstaff, which many CVG-LAS routes do.

During takeoff from Cincinnati Northern Kentucky International (CVG), sit on the Left side for the best views. CVG's primary departure runway 18L sends aircraft southward, and a left (east-facing) seat gives you a clear view back over the Cincinnati skyline, the Ohio River bends, and the Kentucky hills. The downtown Cincinnati skyline with the Great American Ball Park and the distinctive Ohio River bridges are clearly visible during the climbing turn westward. Notable sights include: Cincinnati downtown skyline, Ohio River and its horseshoe bends, Great American Ball Park, Northern Kentucky suburban grid spreading into rolling hills.

When landing at Mc Carran International (LAS), sit on the Right side for the best views. Las Vegas McCarran typically uses runways 26L/26R or 19R for westward and southward arrivals. On the common westward approach, a right (north-facing) seat gives you the Las Vegas Strip laid out in full — the resort corridor is unmistakable from the north side. You also get Lake Mead and the Colorado River on approach from the east. Notable sights include: Las Vegas Strip resort corridor, Lake Mead and Boulder Basin, Spring Mountains (Charleston Peak) to the west, Hoover Dam visible on clear days.

The flight from Cincinnati Northern Kentucky International (CVG) to Mc Carran International (LAS) takes Approximately 3 hours 45 minutes to 4 hours 15 minutes.

The flight crosses the Mississippi River near St. Louis, then the Ozark Plateau of Missouri and Arkansas, the flat Oklahoma and Texas panhandle plains, the Sangre de Cristo and San Juan mountain ranges of New Mexico, the Colorado Plateau with its red rock canyon systems near Flagstaff Arizona including potential views toward the Grand Canyon's South Rim, the Kaibab Plateau, and finally the Mojave Desert transition into the Las Vegas Basin
