How do you get 60%? My upgrade % is over 80% when purchased Y (YCA) fare last year. FTers agree that PN > PZ. If one does not check (babysit) the reservation often after purchase, there is a chance that PN is gone to someone else. Even it is not cleared at T-24 h, it’s priority is still higher than other 1Ks with PPs. Within 24 h, all GSs on lower fares will jump ahead of 1Ks with YBM fares, however.
