Are tickets transferable?

By jimharnock, in 2018 May World Championships

I got my notification that I'm able to get in on Day 1A for X-Wing, which is great. The problem is that I won't know for sure if I can go to the event until the end of March. I'd like to buy my ticket so I don't miss out, but if it turns out I can't go, am I able to transfer my ticket/registration to someone else who can take my place? I realise I can't give someone else my chance to buy a ticket, as per the email, but I'm talking about once the ticket is already purchased.
