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

Welcome to posting, @SydneyFC !

What you're seeing could just be placeholder aircraft types, as Cathay has only relatively recently released the flight numbers for a number of Aria routes through to the end of March.
Note: Melbourne is changing Aria-equipped flight numbers at this time.

Thanks for that information. Looks like flight numbers could possibly change again for the northern summer season by the time I wish to fly. Ah well, nothing like a bit of uncertainty to spice up life.

Aircraft types can change very quickly depending on demand, June next year is a long way away
