Hi all, travelling to hong kong from melb and was pretty stoked when i saw Business Class classic reward seats were available for the dates i want to go. Unfortunately im a few thousand points short of having both legs in business class. If i was to purchase an economy flight with cash, is it safe to assume i can use the points to upgrade to business as I can see it being available for that particular day? One thing I don't want is to buy a ticket and the classic rewards seat is not available anymore
Cheers
