Aircraft type for Aria Suite SYD or MEL to HKG.

[SydneyFC]

Attempting to book Aria suites from MEL to HKG in June 2026, I choose CX104, which is reported to be a 777-300ER by all reviewers. However, when I click on Aircraft details in the Cathay website, it states the plane is an A350-900. Does anyone know if this is a mistake or should I go ahead and book based on the flight number?
Thanks for any insight you can provide. Regards, Allan

Just checked in to CX178. Looking forward to Aria. I thought I missed out after someone booked it right before I did (I had to do some OWA shenanigans first). Then I thought I'd check on Asia Miles instead of QFF and lo and behold it was there.

Interestingly it was available when there was less than 5 overall open seats. I guess CX are one of the airlines to open up their own awards close to departure.
