Sleep, eat, sleep, eat, sleep, sleep more, sleep. I never even bother taking a book. On any flight. OK, I occasionally do things on my laptop.

I find that I no longer get jetlagged since I started getting as much sleep as possible on board. I get a bit insomniac instead after an ultra long haul trip because I sleep on board so much though - which is great, as I get to enjoy myself more.

I almost wish AVOD or any form of IFE didn't exist so that in-flight cacklers don't keep cackling!
