Flight Voucher can be used against the cost of a new booking. It can also be used to add extras such as hold luggage and allocated seating on an existing booking. Although the flight voucher expires in August 2021, you may purchase flights beyond this date subject to availability.
As it cannot be used online, you will have to please call Customer Service Team on 0330 365 5000 to make use of your voucher. They will make sure to apply the standard discount that you would benefit from if you booked via the internet.
Please quote the Flight Voucher reference and code word when calling them.
