If the event organiser allows it, you can edit or re-assign your Tito ticket. Here's how to do it.
Firstly, locate the ticket confirmation email. It will have come from email@example.com. If you cannot find it, you can use Tito's Lookup tool to retrieve it. You will need to enter the same email address you used to register the ticket.
Once you have found or re-sent the confirmation email, click on the link to change details on your ticket.
Your ticket will open in a new tab, and there will be a reassign button at the top. Clicking on that will allow you to enter someone else's contact details.
Once you've done that, click on Re-assign at the bottom to confirm, and that person will be emailed a link to their ticket.
If you cannot see the re-assign option, this means the event organiser has disabled it. In this case you'll need to contact them directly to enquire about re-assigning your ticket. There's a link to their contact information in the confirmation email.
