The AVOD offering for kids on the A380 is outstanding - kills CX. If only they had the kids size headsets.
A lot of 747s have had their AVOD upgraded to the same system the A380 uses.
I have no issue issue with kids in J. I don't even mind children at "fine dining" restaurants (Jacques Reymond in Melbourne), but if they are going to drink Coke at the table, at least put it in a glass and don't leave the can on the table!!!
