You can delete a ticket for a particular activity by going into the "Tickets" section on the particular listing.
Uncheck the checkbox next to "Published", to Un-publish the ticket.

We don't allow the ticket to be deleted permanently, since there might be bookings still associated with the ticket, and hence, might cause errors.
