Volaris allows passengers to cancel their flights within 24 hours of booking for a full refund, as long as the flight is scheduled to depart at least 7 days later. After 24 hours, cancellation fees apply, and the remaining balance is refunded as a travel credit. Volaris does not offer refunds after this period, but travelers can use the credit toward future bookings.
