Some try going to bed a little later each night leading up to the day of travel, but that never seems to work for us. Like Geomom, we take overnight flights to Europe that land in the morning. DH can sleep on the flights but I never do. After arriving, we make it a point to stay moving - eat lunch, sight-see, swim, whatever, until around 6pm. Then, we eat a very light dinner, shower, and go to bed early. We usually sleep very well all through the night and wake up the next morning refreshed and on the correct time zone!
