And so "complementary" J meals will go down too to encourage people to buy F meals?

Mmmm... Enough caviar for the whole J cabin sounds like good! ( means free supply for F flyers)

the news clipping didn't mentioning about F meals for J passengers ordering. i am also doubtful about its implementation for complexity.

Unless I'm extremely hungry else usually I can settle for the standard meal.

When I'm flying for business, given that I always suddenly change my flight I don't think they can earn this money for me

When I'm flying leisure, if I'm flying with friends unless all of us do so, I won't make myself odd by ordering something in a higher class. If I'm flying alone... again likely I'll change flight easily so not a good idea again

Also I feel sorry for the crew, especially in Y when someone don't know such service in advance will definitely question this on board and creating more and more problems and headaches for the crew...

You are being sarcastic right? CX doesn't do red meat justice whether it be filet or rack of lamb. $50-$75 USD will buy you a prime aged steak on the ground. All you can drink Krug, I'll pay for.
