Make your reservation with Allegiant Airlines Trip Flex if you want to avoid paying for modifications or cancellations. It allows you to cancel your reservation free of charge within 24 hours of making it. If the 24-hour window has passed, you may make a one-time modification to the destination, date, or flight without incurring a cancellation or change fee, according to Allegiant Airlines Cancellation Policy. For this, you'll need to adhere to a set of rules.
Keep in mind that Trip Flex may only be purchased when creating a reservation, which is why you can't add it to an existing trip. Depending on the route you are taking, you will have to spend $8 – $20 each segment, per passenger, to add Trip Flex to your booking.
You won't have to pay the normal cost of $75 if you want to change or postpone your reservation with Trip Flex. If the price of plane tickets changes, you are accountable for it; however, your whole change cost will be waived. Passengers who have added Trip Flex to their Allegiant Airlines bookings can change their plans up to one hour before the flight's scheduled departure. It's worth noting that Trip Flex customers can alter or cancel their reservations without incurring any fees, but their flights are still non-refundable.
