Booking a flight ticket online is simple, but there are some essential terms and conditions to be aware of when Cancelling a Allegiant Airlines Ticket. When you're cancelling an airline ticket within 24 hours of purchasing it, this may seem reasonable. As a result, your whole refund will be made in the currency used at the time of purchase. So, if you're a bit smart and you've previously bought a flight ticket, but you need to cancel it right away due to a personal issue, you may do so online or with the aid of a travel agency.
