Harry Reid International Airport (IATA: LAS, ICAO: KLAS, FAA LID: LAS), until 2021 called McCarran International Airport, is the main gateway for international and domestic flights to the Las Vegas Valley, Nevada. It is located five miles (8 km; 4 nmi) south of downtown Las Vegas, in the unincorporated area of Paradise, and covers 2,800 acres (4.4 sq mi; 11.3 km2) of land. Clark County owns the facility and its Department of Aviation, under purview of the Clark County Commission oversees airport operations. In December 2021, the Clark County Commission renamed McCarran International Airport in honor of former U.S. Senator Harry Reid of Nevada, citing a desire to better reflect community values and move away from the legacy of its previous namesake. The airport has four runways and two main passenger terminals (Terminal 1 and Terminal 3) with a total of five concourses; the terminal areas are served by an automated people mover system that connects the central terminal with gate concourses. Reid is one of the few U.S. commercial airports with legalized gaming on airport premises; along with Reno–Tahoe International Airport, it retains slot machines in its passenger terminals under Nevada gaming laws. The airport opened in January 1943 as Alamo Field and initially catered to general aviation.
