So, how do you get to sleep on long flights?

I'm in Hong Kong this week with my wife and daughter to check out the sights (and it would appear, miss the awful weather back home.)

Thankfully, our little girl slept like a rock on both the flight from the USA to Tokyo as well as the Tokyo-Hong Kong leg. My wife got a few hours' sleep on each leg.

I, however, managed only about 90 minutes, and that was just after leaving Tokyo. At least the Hong Kong airport is incredibly easy to get through, because my brains were mush by then.

So what are *your* tips, as parents, for getting good rest on long flights?  (Let's keep liquor and drugs out of it, since you still have to stay clear-headed enough to take care of the kids, right?)

Comment on this post - I'll add your ideas and other research for an upcoming article.
