Viva Aerobus provides a cancellation policy that varies depending on your fare class. If you’ve purchased a more flexible fare, you are generally eligible to cancel your flight and receive a refund or travel credit. However, if you purchased a non-flexible or basic fare, the airline typically does not provide cash refunds, but rather travel credits for future use. Cancellations must often be made within a specific time frame to avoid additional fees, and in some cases, cancellations might not be allowed for ultra-low-cost tickets.
