Why is there no Sydney to Hong Kong premium cabin award seats on Cathay Pacific for December?

Hey guys, trying to book a ticket from Sydney to Hong Kong in December, it says all flights are booked. Is it due to festive season or they have stopped releasing premium cabins on this route?

I’m still seeing revenue flights on sale for those dates. If you are talking about premium cabin award availability, December is typically a popular time so there is just limited availability.
