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. The voucher can be used on easyJet.com or the easyJet mobile app. Only one voucher can be used per booking. 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. The new booking must be for easyJet flights only (including any seats and bags booked at the same time). The voucher cannot be used where other ancillaries are added such as cars or travel insurance. The new booking must be made in the same currency as the voucher.
