Information from the website:
With Flight Credit you can save the amount you paid for your cancelled flight and use it to book with us again in the future.
You can use your Flight Credit for any available flight on vueling.com or our app for one or more bookings until it runs out.
The booking can be made under your name or someone else's and it can be used in conjunction with resident and large family discounts.
How can I use my Flight Credit?
1. Go to Vueling.com or our app and select a new flight.
2. At the end of the process, on the payment page, you will see the Flight Credit section. Once you fill in the details, you will be able to see your current balance.
3. If the price of the booking is lower than your credit balance, the difference will be saved for future bookings.
4. If the total price of the booking is higher than your credit balance, you can pay the difference by card.
