Yes I also asked them to clear them sector by sector. They said :

"This is to let you know that Cathay Pacific does not offer mixed class
upgrade awards. Therefore, you are required to redeem two sets of
upgrade award as follows:

- a Round trip Business Class upgrade award (from Economy Class) between
Singapore and Hong Kong requires 30,000 Asia Miles per person
- a Round trip Business Class upgrade award (from Premium Economy Class)
between Hong Kong and Vancouver requires 30,000 Asia Miles per person"


So I don't see how I will ever get any upgrade. By the time one aector clears the others might not. And if not all is cleared the upgrade booking is canceled. I feel like I'm being played.

@percy HKG-YVR roundtrip still have no available award seats.
