Live TSA Wait Times at Harry Reid International Airport

Harry Reid International Airport (LAS), formerly known as McCarran International Airport, serves as the primary airport for Las Vegas, Nevada. Located just five miles south of the Las Vegas Strip, it’s one of the busiest airports in the United States, handling tens of millions of passengers each year.

LAS is a key hub for Southwest Airlines and a major destination for Spirit, Allegiant, and Delta. The airport operates two passenger terminals — Terminal 1 and Terminal 3 — connected by an inter-terminal shuttle. Each terminal is designed with traveler convenience in mind, offering quick access to gates, baggage claim, and ride-share zones.

Known for its slot machines, modern design, and proximity to world-class resorts, LAS delivers a travel experience that’s uniquely Las Vegas — vibrant, efficient, and always open.

Harry Reid International features multiple TSA security checkpoints distributed across its two main terminals:

• Terminal 1: Handles domestic flights for Southwest, Frontier, Spirit, and Delta.
• Terminal 3: Serves international and select domestic carriers, including United, JetBlue, and Alaska Airlines.

Both terminals have TSA PreCheck and CLEAR lanes, with signage guiding travelers to expedited screening areas.

Security screening typically begins around 3:30 a.m. and continues until the last departing flight, often past midnight. Peak hours occur between 5:00–9:00 a.m. and 4:00–8:00 p.m., coinciding with major departure waves. Travelers are encouraged to arrive two hours before domestic flights and three hours before international.
