Correct me if I’m not understanding your question, but you have until your ticket expires to upgrade to an annual pass. My tickets, for example, were valid from September 24-27. I had until September 27 to upgrade to an AP, and the AP expires 365 days from when I upgraded on September 25. You don’t have 364 days to upgrade to an AP since your ticket expires. But you can upgrade anytime until the ticket expiration.
