Report any missing items to your airline at once. Pack fragile items in containers designed to withstand rough handling. Baggage can easily tumble in an aircraft cargo compartment during takeoffs, landings or rough weather. Never pack any items that are very valuable, irreplaceable, delicate or have sentimental value in checked luggage. Be aware of your airline's baggage limits.
Most airlines allow each passenger to check two pieces of luggage and carry-on only one piece.
Hang on to your baggage tags. They are your only proof that you checked luggage with an airline. If your baggage does not come off the conveyer belt at your destination, don't panic. Ninety-eight percent of all misplaced luggage is returned to its owners within hours. If you believe that your luggage has been misplaced, notify your airline before you leave the airport.
