Avianca Airlines cancellation policy varies depending on the type of ticket purchased. For tickets purchased on or after March 1, 2023, customers can cancel or make changes to their reservation for free within 24 hours of booking. After that, cancellation fees will apply, which depend on the fare type and destination. Avianca may also charge a service fee for changes or cancellations made outside of the free cancellation window. In some cases, Avianca may offer a credit voucher instead of a refund. It’s recommended to check the specific terms and conditions of your ticket for more information on Avianca’s cancellation policy.
