Do you want to know when to cancel a Breeze Airlines flight to get a reasonable refund? A 24-hour rule is given in the Breeze Cancellation Policy which allows the travelers to have the benefit of free cancellation and free refund if the reservation is canceled by the traveler within the time span of 24 hours from the time of booking. The only condition that applies to this is that the scheduled departure of that flight must be at least 7 days from the date of cancellation.
