A point to add after reading the string of messages on this topic is that what are we defining as Kids?

I normally find that it is the older kids (10-16) that are the problem passengers.

Several times recently in Business I have had parents with younger children directly infront or behind me, and they have been marvellous.

I am only 20 and fly in Business Class/Premium Economy whenever possible, I get quite a few stares from other passengers who think that I don't belong in 'their' cabin. Why is this? I have paid a full adult business fare like anyone else?

What makes me laugh though are the older people flying in Economy that think they should be upgraded because they are wearing a suit etc, the looks I get at check in when these people see me checking in at the business Class counter is unbeleivable, whilst they are stood in the huge Economy check-in queue. I love the fact that I can use the Business check-in even if I am flying Economy. It's worth it to see these peoples reactions!!

Thanks,
Richard
