Up to 24 hours after booking, Avianca Airlines offers free flight cancellation. There won't be a cancellation fee if the passenger changes their flight within 24 hours of purchasing their ticket. Additionally, if travelers change their intentions within seven days of purchasing their ticket, the airline will charge a cancellation fee. Additionally, the airline will only offer flight compensation in the event of an independent cancellation, whether it be voluntary or involuntary, in accordance with Avianca 24hour cancellation policy. After a specific period of time, you can rebook flights using reward points.
