So I'm booked on LAX-HKG roundtrip in R (PEY) and trying to use Asia Miles to upgrade to business. My inbound upgrade has been confirmed but I'm waitlisted for my outbound flight. I've been calling Asia Miles every day to see if there's availability but nothing so far. I'm confused as to what happens now that my waitlist is expiring today (T-4). Some agents have told me to keep calling, while others have told me that since my waitlist is expiring, not to even bother calling back because I have no chance. Anybody with any insight?

BTW, here's the load for my flight:
