I think I would still aim at flying Y. But for my parents, after this BR incident, they no longer believe in any FFP (neither do I ) so I guess if they will purchase J ticket ever since no matter which airlines they fly.
So CX J class by purchased tickets would at least guarantee an equivalent if not better service!? Do they discriminate different fare booking classes by a large degree?
They're not suppose to discriminate their level of services, but they do give extra attention to DM/GO flyers. But everyone should get the best J service that CX provides.
