About Allegiant Air
Allegiant Air is a Las Vegas-based ultra-low-cost airline that connects smaller US cities directly with vacation destinations like Florida, Las Vegas and Phoenix. Many routes run only a few times a week, so changing a flight can mean moving by several days.
Whether you need to move a date, fix a name or choose better seats, changes on Allegiant Air depend on your fare type and current airline policy. We check the details for you and confirm all costs up front.
