It is interesting that I don't suffer from jetlag on those long international flights but my friends do. I am able to quickly accustom to the local time and meals. I know that being in my 20s is a factor but again my friends around my age have severe jetlag on the long flights.

I sleep 8 hours the night before the trip and get up early in the morning and stay up until the flight for international flights. I go right to sleep after the meal service and wakeup before breakfast. I am able to keep myself awake until a civilized bedtime at the destination. I may take a 40 minute nap if I am exhausted which is rare.

On short flights to the East Coast from California or to Hawaii I get up early in the morning and stay up the entire flight until I land. If I arrive in the morning I go right to the pool or beach and if I arrive in the evening I have dinner and go to sleep.

I can get 5-6 hours sleep in redeye flights and then in the middle of the day I take a 40 minute nap and then stayup until the local bedtime.

Overall I think jetlag is very manageable.
