A voucher can be issued in almost any euro value. The owner can use the relevant amount to pay for each of our sightseeing flights and, if necessary, pay the rest himself. You can't give more flexibly.
Redemption information: Simply enter the voucher code in the shopping cart. The value of the voucher is deducted from the amount paid - it can be that simple. If you have several vouchers, add the codes to the shopping cart one at a time.
