Harry Reid International Airport, also known as LAS, primarily serves Las Vegas. Located about three miles from the city in the unincorporated town of Paradise, Nevada, the airport has seen a growing number of travelers in recent years. Case in point? LAS served a record 57.6 million passengers in 2023. If you're over 21, you can play the ubiquitous slot machines while waiting to board your flight — after all, it's not Sin City without the ringing of bells and buzzers in the background.
