Allegiant Airlines Cancellation Policy
Allegiant Airlines cancellation policy allows its passengers to cancel the ticket in the next 24 hours from the time of booking and the airline does not insist on charging any kind of cancellation fee and the refund for this particular cancellation will be done to its original mode of payment. However if you want to cancel your ticket after 24 hours from the point of purchase, then a cancellation fee of $75 will be deducted from the total amount and the rest of the amount will be refunded back to the card that you used during booking.
If you happen to miss your flight or cancel before a week from the time of the departure then the airline will not provide any kind of refund.
