Sit on the Right side of the plane for the best views on flights from Las Vegas to Chicago. The right side wins overall due to the spectacular Las Vegas and Red Rock Canyon departure views. The mid-flight terrain over Utah, Colorado, and the Rockies also favors the right (south-facing) side with views of the Colorado Plateau and Rocky Mountain foothills, though at cruise altitude both sides see similar terrain. The Chicago arrival is better on the left, but the departure spectacle tips the balance to the right.

During takeoff from Mc Carran International (LAS), sit on the Right side for the best views. Departing Las Vegas typically on runway 26L/26R heading west-northwest, the right side faces north and gives you a clear view of the Las Vegas Strip laid out below, then the Spring Mountains rising to the west. The left side faces south toward open desert with less visual interest. Notable sights include: The Las Vegas Strip (visible below during initial climb), Red Rock Canyon escarpment to the west, Spring Mountains (Charleston Peak at 11,918 ft) to the northwest, Lake Mead reservoir to the northeast.

When landing at Chicago Ohare International (ORD), sit on the Left side for the best views. Approaching O'Hare typically from the southwest on runways 10L/10R or 9L/9R heading northeast, the left side faces north and northwest giving views of the Chicago suburbs and eventually Lake Michigan's southern shoreline. The right side faces south toward flat Illinois farmland with little visual interest. Notable sights include: Lake Michigan southern shoreline and Chicago lakefront, downtown Chicago skyline on the horizon to the east, O'Hare's distinctive multi-runway complex visible below on final, suburban Cook County grid spreading to the horizon.

The flight from Mc Carran International (LAS) to Chicago Ohare International (ORD) takes Approximately 3 hours 30 minutes.

The flight tracks northeast over southern Utah's Colorado Plateau with its canyon systems and red rock terrain, then crosses the Rocky Mountains over Colorado near the Wasatch and Uinta ranges, transitions to the flat Great Plains of Nebraska and Iowa, and finally crosses into Illinois farmland before descending into Chicago. The Four Corners region and the distinctive plateau-and-canyon topography of Utah are the most visually striking mid-flight features, visible roughly 45-60 minutes after departure.
