I remember the days all baggage tags were color coded. Now with the barcode they are all white. My bags didn't make it home from my last cruise and with that barcode the agent at my home airport new exactly where my bag was and it came in the next day and was delivered to my home. In the past we wold wait to add the cruise line tags at the pier "wrong" they should be added before you go so they do know to bring them to the correct ship. Great remember to be sure to put them on at home.
