Airlines charge a fee for changing the travel date, which is calculated as follows: penalty fee plus any fare differences between the cost of the originally purchased ticket and the cost of the airline ticket for the new travel date.
In some cases, changing the date of an existing ticket may result in higher costs than purchasing a new airline ticket, due to the penalty fees imposed by the airline.
If you have chosen the Vola Flex service and want to change the date, you can request a free rescheduling of your booking up to 24 hours before the flight.
