Refunds and changing your ticket.
If you haven’t used your ticket, you may be able to claim a refund.
If you already have your tickets but change your plans for any reason, you can still ask for a refund: you may have to pay a £10 admin fee.
For tickets purchased online, follow the prompts through your online account under the "Manage my tickets/Refunds" section.
Make sure you do this within 28 days of the date on your ticket.
