The previous record for the airport's passenger total was set just this July with 4.86 million flyers.

So far, there have been 43.72 million passengers reported at the airport through the first 10 months of the year. That's an increase of more than 37% year-over-year.

"Serving more than 5 million passengers in a single month is a milestone achievement, and is further evidence that Las Vegas remains amongst the most in-demand destinations in the world," Rosemary Vassiliadis, director of aviation for Clark County, said in a statement. "But we know it is not just visitors coming through our airport, our locals are also choosing to travel at a high volume."

Vassiliadis says the county will begin a months-long project in early 2023 to increase the parking options in and around the airport's garages.
