Las Vegas International Airport

Harry Reid International Airport (LAS) is the main commercial facility for Southern Nevada. Clark County owns it, and its Department of Aviation runs it as a business enterprise fund. The airport receives no tax revenue from the county or the state. In 2024, over 58.4 million passengers used LAS, with more than 550 flights arriving daily from over 150 cities. 

Currently, over 30 airlines are serving the airport, with Southwest being the largest carrier. It carried over 21.5 million passengers from June 2025 to May 2026. Other major carriers include Delta, United, American Airlines, and Frontier Airlines.

The busiest domestic routes through LAS include Los Angeles, Denver, and San Francisco. For international routes, London Heathrow, Mexico City, and Toronto are among the busiest. The airport also handled 258.2 million pounds of cargo in 2024.

LAS has two main terminal buildings, Terminals 1 and 3, serving five gate areas: A, B, C, D, and E. Terminal 1 serves the A, B, C, and D gates. Terminal 3  serves the D and E gates and houses international arrival facilities. The D gates are located in a separate satellite concourse and are connected to the terminals by an automated tram. Both terminal buildings have their own ticketing, check-in, baggage claim, dining, and shopping areas.

Notably, LAS is one of only two U.S. airports with legal gaming. The airport has over 1,400 slot machines available in both terminals, across all concourses, the baggage claim areas, the Terminal 1 Esplanade, and the airport’s food courts.

LAS Airport opened on December 19, 1948. For decades, it was known as McCarran International Airport. In February 2021, Clark County commissioners voted to rename the airport after Harry Reid, who represented Nevada in Congress from 1983 to 2017. The new name became official on December 14, 2021.
