I'm one of those weird ones who enjoys being on a plane. Like the Seinfeld bit goes, it is a tiny snapshot of life... tiny tables, tiny cramped seat, tiny bottles, tiny food.
Anyway, I feel like this article just throws everything at you.
The following works very well for me:
1 - Adjust your sleep to reflect your destination. Advance or delay your body clock according gradually prior to your trip.
2 - Water. Drink lots of it inflight.
3 - High-Protein, low carb meals just before travel and inflight.
4 - Walk around on a plane or use compression.
