If a passenger finds themselves in need of an Avianca Change Flight, they can find the instructions and contact information on how to make amendments on the airline's website. The airline provides specific instructions for how to change flights and pay for any additional costs associated with the changes. Passengers are encouraged to check in, update their flight details, and print their boarding passes before arriving at the airport. Avianca Airlines also offers certain protections to passengers who need to make changes to a flight date or time. If an amendment is made that results in a higher fare, then travelers are eligible for a credit voucher in an amount equal to the difference between fares.
