   If you have to fly through several time zones in 12 hours or less, you may feel an upset of your body clock after the long flight. This is jet lag. Doctors say the best thing you can do is rest on the plane and perhaps have a drink of water and rest at your hotel when you arrive.
   Larger airports with lots of international traffic have employees who speak languages besides English to help you, but smaller ones don’t.
   You can bring a total of one quart of alcoholic beverages and one carton of cigarettes (200 cigarettes) into the U. S. duty free. If you bring more, you have to pay tax.
