When it comes to travel, either for business or pleasure, one of the things people forget is to account for jet lag.

Whether it be a domestic flight with only an hour or three-hour difference, or a long-haul international flight where there could be, up to an 16-hour time change, getting prepared to deplane and have the energy to actual get to work or start the holiday is very important.

Since mobile phones are "smart" enough to automatically change its time, be sure to wind your wrist watch to the local time of the destination. 

The reason for this is to fool the mind or circadian rhythms (i.e. body clocks). For example, if you are going to Provence, France, from Newark, NJ, and the local time in Newark is 8: 15 p.m., fixing the time to read 2:15 a.m., which is the time in Provence, the mind will think it is 2:15 in the morning, and, in time, adjust.

If your trip is taking you from a time zone in an evening hour, to one that is in an morning hour, getting sunlight (natural) while sitting in the plane, will aid in the adjustment.

Might sound crazy, but it works.

Another issue is sleep while on the plane, which is hard to be definitive about.

Some people feel it helps, while others think it is the main reason why they become jet lag to being with.

The only advice--figure it out for yourself. While on the plane, try sleeping, if upon waking up you feel better and ready to take on the day, or night (depending on the time at the destination), then it works (in your specific case). 

Staying hydrated is also critical in beating the lag.

Dehydration caused by dry surroundings in higher altitudes, your body requires fluids to replenish itself. And water works better than any juice, fizzy drinks. Don't drink alcohol--it only dehydrates you further. Remember, a dehydrated body slows down recovery and might even be the cause you fall sick on the trip.

Another bit of advice, though others might feel different.

Stay away from pills.

Happy Traveling.
