The processing assistance fee is a fee of 30 euros (per booking) that we charge to handle all communication with the airline. The objective is, of course, to be able to give you the best possible solution for your reservation. This applies to all ticket changes and cancellations, for example, if you have a voucher and you want to use it to reschedule a new ticket, if you just want to reschedule a trip or if you want to cancel and request a refund.
