Put all important information — such as flight numbers, traveler’s check numbers, customer service numbers for your bank (in case you lose or have trouble with a credit card), insurance policy information, and home telephone numbers — on credit card size cards to carry in your wallet. (Some travelers even take the trouble to laminate their cards.)
If you carry a smart phone or PDA, consider using applications on your phone to store this information, too. Your phone’s calendar program is a good place to store flight times and numbers. It’s good to have a paper backup of this information, though, in case you forget to charge your battery.
There is some information you definitely don’t want to include, though. Social security numbers, copies of credit card and bank account numbers, or other information you wouldn’t want to misplace shouldn’t be carried on your person while traveling.
