So THAT'S What All Those Codes On Your Baggage Tag Mean

To a checked bag, the airport is one big trip.

By the time most checked bags join you aboard an aircraft, they've already taken a six-mile journey through the bowels of the airport.

It all begins with a 10-digit code on your airline-issued luggage tag, which includes numerals for your airline, a serial number unique to your specific bag and characters that correspond to any special instructions about how the bag should be handled.

Then, your luggage sets off on a "giant hidden railway" with 23,000 motors and some 100,000 wheels to carry it safely to its destination.
