Warning! The TUI fly Gift Voucher is only valid if you book your flight tickets directly with TUI fly at www.tuifly.be. A gift voucher can only be used on one booking for its entire value. It is not possible to divide the value of one gift voucher over multiple bookings and we do not reimburse any price differences between the value of the gift voucher and the value of the booked flight(s). However, it is possible to use multiple (max. 10) gift vouchers on one booking. More information can be found here.
