It is a good idea to book your UIKonf ticket early to make sure you get one. On the other hand, booking so early is not easy because life is life and there are unexpected circumstances. That is why we have a very flexible refund and transfer policy:
Due to PayPal rules, we cannot refund your ticket after 60 days. So if you paid with PayPal, it is either the deadlines above or 60 days after purchase whichever comes first.
