I always change my watch as soon as I get on the plane. I do this even with a short change (like 1 hour NY-CHI). I try to adjust my sleep to the destination - so when it is bed time (around midnight) I will take a "PM" pill to help on a long flight. When I get to my destination I will immediately get on that day's schedule, do as much as possible and and get to sleep at as close to my regular time ( again, with the help of a sleep aid if needed).
