I can't comment on CX post-Covid except to say that I'm just back from a Covid-delayed honeymoon in the UK/Europe and we flew EK in F for only a little more than CX wanted for J to LHR. EK F varied between (as good as CX F used to be plus a shower) on the A380, to (out of this world good) on the "game changer" 777.

And I learn from others that almost all CX cabin crew are still wearing masks! That for me is a show-stopper immediately in a premium cabin.

So as someone who has I guess about 1.5MM on CX and was Diamond for many years pre-Covid, I don't think I'll be back any time soon.
