About LAS

Located barely two kilometres from the Las Vegas Strip, the airport is famous for slot machines in its concourses. It is the largest station in the Southwest Airlines network. Traffic has surged past pre-pandemic levels on the back of Las Vegas's sports and events boom.

Commercial aviation moved to the current site south of Las Vegas in 1948, when McCarran Field opened, named for Nevada Senator Pat McCarran. The airport grew in lockstep with the casino resorts rising along the nearby Strip. Its terminals became famous for a uniquely Nevadan touch: banks of slot machines greeting travelers at the gates. Jet-age expansion brought a modern terminal in 1963. The airport rode successive Las Vegas booms, from the Rat Pack era through the megaresort explosion of the 1990s.

Terminal 3 opened in 2012 to handle international flights. In December 2021 the airport was renamed Harry Reid International after the longtime Senate majority leader from Nevada, retiring the McCarran name.

Today it ranks among the busiest airports in the United States despite functioning almost entirely as an origin-and-destination leisure gateway rather than a connecting hub. Southwest Airlines carries the largest share of passengers, while Allegiant, Spirit and Frontier maintain major bases. Events like CES and marquee sports weekends produce some of the sharpest traffic peaks in American aviation, with Formula 1 and the Super Bowl adding to the calendar in recent years.

How LAS operates today

Harry Reid International operates four runways in two perpendicular pairs squeezed between the Strip, freeways and mountains, with Terminal 1 serving domestic carriers led by Southwest and Terminal 3 handling international and additional domestic flights. Traffic is overwhelmingly point-to-point leisure, producing enormous weekend and event-driven peaks tied to conventions, fights and festivals.

Summer heat and high density altitude can trim aircraft performance, and the desert setting funnels arrivals over spectacular terrain. The airport also hosts a discreet private terminal for the government's unmarked 'Janet' fleet shuttling workers to classified Nevada test sites.
