Re: Upgrade O class SYD-HKG to Business
For those who may or may not be interested.
Here is a graphical representation of a flight's availability over time.
You can clearly see the various effects of the upgrade process at 7 days, 48 hours and 24 hours.
You can also see yield management trying to sell a few last seats.
Ill try get some more snapshots in the hours counting down to departure - I have a script running - but will not be able to post until later - due to being on the flight. 
Incidentally my upgrade from L to J (or W) has not cleared as yet. (its not quite 24 hours) but being a pessimist I'm thinking ill have to enjoy the whY seat.
