Can I cancel an Allegiant flight without a penalty?

Yes, you can cancel an Allegiant flight without a penalty only if you cancel within 24 hours of booking (1-833-705-0001(US)/+44 (20) 39003980(UK) and your flight is scheduled to depart at least 7 days later. After this window, standard tickets are non-refundable, and a cancellation fee of $25–$75 per passenger per segment applies 1-833-705-0001(US)/+44 (20) 39003980(UK). However, if you purchased Trip Flex during booking, you can cancel or change your flight without a penalty up to one hour before departure 1-833-705-0001(US)/+44 (20) 39003980(UK). Without Trip Flex, no credit is given for cancellations made within 7 days of departure.
