Looking to travel on Cathay in April from Sydney to HK then to Shanghai, flying in economy. As far as I can tell, it's not a codeshare flight.

On my eticket, under "Bag", it says that I have an allowance of "30K" and it says 30kg on the Qantas membership site (I've linked my QFF number).

However, the Cathay website says that economy is only allowed 20kg and I don't have enough status on any membership program that would give me any upgrade in the check-in baggage allowance.
