It seems a little vague if this is for ALL A333s or just for the current long-haul J configged A333s. As CX regulars know, there are a ton of A333 configs now including the new 33As with basically three classes of seats (two types of J). The One Mile blog guy on that link is clearly implying Aria Studios are replacing regional J on A333, but I'm not so sure. He randomly mentions the A321s, forgetting about the huge A333 fleet variation, as well as the 773 regionals. The posters above are consistently better informed. Strikes me of racing to post a scoop, maybe well intentioned but not quite right.
Worth pointing out that CX recently refurbed regional J on a lot of planes already, right? Including those 33As, maybe other A333s and some 773s? Strikes me as wishful thinking they're going to scrap that for Aria Studios a year or two later.
Thanks for posting. Hope the event went well! Sorry to miss it.
