About Harry Reid International Airport

Harry Reid International Airport, located just minutes from the Las Vegas Strip, is Nevada’s busiest airport. It serves both domestic and international travelers and operates two main terminals: Terminal 1 and Terminal 3. Due to the city’s tourism-driven economy, passenger traffic at LAS fluctuates more dramatically than at many other U.S. airports. As a result, security wait times at Las Vegas airport can change rapidly, even within the same day.

When Are Security Lines Longest at LAS?

Las Vegas travel patterns differ from traditional business hubs. While weekdays can be busy, the largest crowds usually appear around leisure travel and major events.

Busiest Days of the Week

During these times, Las Vegas Airport Security Wait Times are often unpredictable, making it important to arrive early.

Terminal 1 vs Terminal 3: Security Differences

Terminal 1

Terminal 1 handles the majority of domestic flights and experiences the highest passenger volume. Because of this, security lines here tend to move slower, especially during morning rush hours and weekend peaks.

Terminal 3

Terminal 3 serves international flights and select domestic routes. While often less crowded than Terminal 1, security wait times can still increase during peak international departure windows.

Knowing which terminal you’re flying from can help you better plan your arrival time.
