Also another point regarding beverages. I find CX offers the BEST non alcoholic selection in both J and F:

1) Non Alcoholic Cocktail (rotate between 2)
2) Espresso Coffees (Nespresso) (in J Class as well)
3) Premium Chinese Teas (in F Class)
4) Iced Drinks (eg Chocolate, Coffee)
5) HK style Milk Tea
