Help - I've lost my ticket! Follow
If your ticket is a paper ticket the we're really sorry but once you have collected your ticket from a self-service ticket machine you are not able to claim a refund if you lose it. This is because you need to return the ticket as proof before a refund can be processed. Check your pockets, wallet, handbag, the little pocket on your laptop bag, under the cushions, but if you can't find it you will have to buy another.
If your ticket is an eTicket, then just go to the My Tickets section of the app where you will locate the QR code you need to travel or find the emailed version of the ticket which can also be used to travel.
