The gift vouchers can be canceled free of charge within 2 weeks. No difficult questions, no hassle. You just get your money back. You will be refunded the purchase amount via the same payment method with which you have paid. So if you have paid with iDEAL you will be refunded to your bank account. If you paid by credit card, it will appear on your credit card statement. Cancellation is no longer possible if your appointment at the flying school is scheduled within 24 hours. Maybe cancellation is not necessary at all, you can also change the gift voucher via 'Make reservation' to another flying lesson. If you want to cancel, please send an e-mail to email@example.com and mention your voucher number.
