Additional information:
Easyjet voucher is not nominative. You do not need to travel before the expiry date, you can book onto any flights that are on sale at the time you redeem your voucher.
If the new booking is greater than the voucher value, the difference must be paid by card. If the new booking is lower than the voucher value, the remaining value is stored and can be used on future bookings within the expiry date.
