When my brother takes his two boys on long haul flights, they drug them up with antihistamines. And when they aren't in their drug induced comas, they have their game boys to occupy them. They are flying from Sydney to Vienna next week and my Sister in Law has it all worked out...she hopes
Before the flights she also talks to them about their behaviour on the plane. I think all parents shuld do this..no matter what class they fly in.
At least they have the good sense to only fly in Y.
