When an airline cancels a flight that had been planned to take place, it is known as a sunwing cancellation policy. There may be a lot of causes for this, such as weather conditions, mechanical issues with the aircraft, or insufficient demand for the Sunwing Airlines route. Passengers have the option of receiving a refund or finding alternate transportation if Sunwing Airlines cancels a flight. In rare circumstances, passengers can also be eligible for reimbursement for specific costs incurred as a result of the cancellation.
