Because each aircraft has a different policy, it's important to read the fine print before you reschedule your flight. That way, you can be confident that you're booking with a transporter that has a reasonable dropping and flight change policy. The Avianca Change Flight Policy is helpful for travellers who need to reschedule their flights and have a flexible schedule. Within 24 hours of booking, it allows customers to modify their tickets without incurring any further fees. If the travellers choose not to use the free change window, they will be required to make a little payment as the carrier requests. Travelers would be required to pay the difference in price if the amount for the previous flight was not exactly the same as the amount for a subsequent flight.
