About Allegiant Air at LAS
Allegiant Air is a Las Vegas-based ultra-low-cost carrier (ULCC) that connects Las Vegas to more than 130 small and mid-sized cities across the United States. Because LAS is Allegiant’s home airport, the airline operates a high volume of daily flights from Terminal 1. Concourse B is the busiest concourse at Terminal 1, housing Allegiant alongside Spirit, Frontier, American, and other carriers.
Allegiant charges separately for carry-on bags, checked bags, and seat selection. Budget extra time at check-in if you have baggage to pay for or questions about your booking — Concourse B security lines can be long on peak travel days.
