As indicated by Volaris 24 hour cancellation , the cancellation would not be applied if the flight booked within 7 days of scheduled departure. If an Air ticket is reserved by any outsider travel service, via the web or offline medium, travelers would be charged a cancellation expense and the ticket will not come under the cancellation policy and refund. If passengers want to gain a full refund against cancellation, then passengers should cancel their booked ticket within risk-free time. Visit our website to know more.
