Since its inception more than two decades ago, Las Vegas-based Allegiant Air has grown to service hundreds of nonstop routes across the country, including several that fly in and out Nevada.

Allegiant adds stops according to demand from customers, said Kristen Schilling-Gonzales, Allegiant’s vice president of planning. And, she said, that demand often includes one destination: Las Vegas.

Allegiant, which recently added a route to Las Vegas from Lexington, Ky., isn’t the only carrier at Harry Reid International Airport experiencing growth.

A total of 36 domestic markets were added by 10 different airlines to the airport in 2022, and 17 of those were from underserved markets, said Lori Nelson-Kraft, senior vice president of communications at the Las Vegas Convention and Visitors Authority
