The only tag you need on your bag is your deck/cabin number in big bold letters.
This is indicative of more bad cost cutting even stupid cost cutting. Given a fair wind and providing these are adhesive it should be enough to get your luggage to your cabin but being a belt and braces man myself I would also add a strong luggage label to the handle with your name and cabin number on that as well, normally the deck number is integral with the cabin number.
Whilst we are on the subject I would emphasise that you should have a stick on label inside your cases with your full name and address and mobile/cell phone number on it. Airports, as we have found to our horror, have a tendency to loose luggage occasionally and the label is never lost when on the inside which gives you a major chance of recovering your luggage. The luggage tag on the outside should be shrouded so that your address can only be seen by a thorough investigation and therefore not immediately obvious to opportunist thieves whilst you are away. Hope this is helpful and not teaching you to suck eggs. .... Neil
