McCarran International Airport
McCarran International Airport is an international airport in Paradise, Nevada, that serves the Las Vegas Valley, a metropolitan area in the United States state of Nevada, roughly 5 miles south of Downtown Las Vegas.
The airport opened to airline operations in 1948 after being built in 1942. Since then, it has grown and included many cutting-edge innovations, such as shared-use facilities. There are four runways and two passenger terminals at the airport. The Marnell Air Cargo Center is located east of the passenger terminals, while fixed-base operators and helicopter businesses are located on the west side of the airport. Allegiant Air, Frontier Airlines, Southwest Airlines, and Spirit Airlines all use the airport as a hub. The airport also served as a hub for America West Airlines, which continued to serve as a hub after the merger with US Airways in 2008. It is the busiest airport in the United States that does not serve as a hub for one of the three legacy carriers in the country.
