On Aria Suites rollout, CX's Vivian Lo told me at the Aria launch "when we launch a destination we would like to launch daily" – so until there's at least three in the fleet (as required for likely London launch) then yeah, they'd be likely to lock down a single 777 flight on any relatively short route. Singapore and Tokyo could indeed be good candidates.

I have a few flights to US and would switch them to CX if it's Aria. Surprised they don't launch Aria to the more lucrative international routes but rather intra-China. There might be geopolitical reasons but that's not for me to guess, but I guess I'll stick with the Room for ANA for now.

NVM, just saw this youtuber and Aria is really not impressive, and the TV and table are big turnoffs. I'll stick with the Room for my China-US travels.

What's so surprising to deploy a completely new cabin product on short haul routes to let cabin crew get familiarised? And if you could spare some time to read just 1 page of this thread you would notice the reply just above yours has explained why intra-China / intra-Asia flights in the first few months.

Anyway, I think you would like Aria if the Room's small and confined footroom is to your taste, although the bed of Aria should be no where as hard as the Room.

The HKG-PVG CX368/367 pair in Nov was initially 77K configuration, then was changed into a 77J configuration.
Maybe there's a chance. Maybe as well as CX542/543.

Because those longer-range routes require three aircraft to service a single daily route, and right now Cathay doesn't have three Aria'd 777s.

Cathay right now has one, and soon it'll have two, and those are being assigned to short-range routes where they can still lock in a reliable daily frequency on a particular flight while also maximising crew familiarisation for the new fit-out (and bonus, generating good publicity & media exposure across several regions).

Cathay plans to have three Aria'd 777s around Jan which is when it'll take a long-range route (likely London) under its wing. I'd imagine some solid medium-range routes would follow, eg you only need one plane to so HKG-SYD-HKG, ditto for AKL.

Does anyone think that the A350-900 and A350-1000 may get a slightly updated Aria Suite like the case of Safran Cirrus seats, compared with B777-300ER ?

While that's still a long way away, I would be surprised if the new A350 business class was not 'Aria-ish' to some degree. But to what extent, remains to be seen...

I think a key priority in any A350 upgrade has to be the J layout and in particular the lavs which are poorly located, too small and too few. I did HKG-JFK the other day and was reminded just how hard it is to get changed into sleeping gear for the overnight flight in the lavs on the -1000 (and I'm not a big guy...).

If It has to be CX542/543, CX must think of roaster as it is an outport parked flight pattern

Vivian Lo told me at the launch event that it will be Tokyo/NRT, not HND. They do not want the 77J sitting on tarmac overnight elsewhere I supposed. I was disappointed as I actually have a HND trip in Dec.

Well, that's not a surprise if it's NRT.

HND is premium-heavy. 548/549 must serve F in some sense. For 542-543, that's an overnight parking flight, so they must consider if 77J parked at outport, what can they do.
Eventually, Aria will serve HND but I guess that would be at least S25 (It seems CX planned to cancel the 548/549 77A arrangement, cannot book First for HND in the S25 schedule)

I am a big guy, medium fat, and it works. Once you have flipped down the bench, you have a suitable sitting location and can maneuver around. No problem.

Aria seems to have less seat pitch than the old Cirrus. That's why they were able to fit a lavatory in front of Door 2

The size of the lavs are pretty standard but I truly believe the layout needs to change - one upfront next to the cockpit on the left and 2 minimum (ideally 3) behind door 2 would solve all the noise and light issues.
