Volaris Flight can claim full refund by informing the airline within 24 hours of booking the ticket. However, for offline cancellation, dial the number listed country-wise on the official Volaris website. Individuals are also informed that canceling a ticket also involves application of penalty fees. Passengers wouldn’t get refunds if they cancel after 24-hour of the ticket purchase, and if the flight doesn’t depart or arrive from the U.S. https://www.flightzticket.com/volaris-airlines-cancellation-policy
