According to the Allegiant Cancellation Policy, some of the tickets available on the official website have restrictions. Customers are urged to review the ticket limits before making reservations to avoid last-minute disappointments. There won't be a cancellation or refund option on these tickets. You should be aware that tickets included in vacation packages usually do not have refund policies. This may or may not be constrained by the amount of time between when they are acquired and when they are to be used. Please be informed that if a passenger wants to cancel a ticket together with any hotel reservations, car rentals, tour services, etc. that were made, there will be a cancellation fee.
