JamesSpooner's notes on international travel.

• Pack some melatonin pills - they reset your body clock. It's a herbal thing, grab it from a chemist. You can also get non-prescription sleeping pills - the harder ones nail you.
• Take your shoes off after takeoff - your feet swell on the plane.
• Buy a neck cushion and inflate it 1/2 way so it supports you but your head touches the headrest.
• Take a good pair of headphones, noise cancelling if you can
• Get as much sleep as you can on the plane - makes the flight go faster if nothing else
• Take a bottle of water.
• Try and get an exit row seat but make sure it's on the outside of the plane and an aisle seat. Check in early and ask. Make sure it's not by the toilet either. Whatever happens, the further up the front of the plane you are the better - behind the wings sucks.
