Hello all - after hours of searching I couldn't find any insight on how to see if an ANA economy to biz upgrade is available. I want to use PP and I understand the flight number issues etc. Does anyone have any insight on how to see availability before booking a ticket? If you sign up for the ANA rewards program then search, there is "some" information when you go to book a flight but the codes used are PY and C and its not clear if its available or waitlisted.
