Update: I booked my trip on UA. (ORD-SFO-HND-SGN, HKG-SFO-ORD in January. I called the 1K line who spent an hour changing the HND-SGN flight to a native ANA flight# so I could apply PP. I used the link on United.com and applied 40 PP for the upgrade to Business which cleared immediately. Sweet!

However two other issues popped up:

1. I had PP applied on the SFO-HND (UA metal) and also HKG-SFO (UA metal) both waitlisted before they tinkered with re-issuing the ticket. But now my account shows that I am not waitlisted on either flight and I cannot add them back. Calling 1K again, they swear I am waitlisted even though it doesn't show it on my account as being waitlisted anymore. Is this a known technical glitch??
2. The PQP totals dropped by about $700 after I used PP on ANA.. I am not sure if that's accurate because maybe I am now earning lower PQP on a ANA partner airline method, or if the totals are all just really janky.
