On the way out, put the name and address of your hotel so that your bags can be delivered more easily. On the way home, put your business address on the tags, so that they can be returned to you during business hours without your having to wait around for them. Of course, if you don't get them when you arrive, you will have put in a claim, but they have to find the bags in the system before they can get them to you. I keep a copy of my business card in the luggage tags at all times, and add a top slip for each trip on the outbound leg.
I put a copy of our full itinerary inside the bag, in a plastic page protector that is permanently attached to the inside flap. of the suitcase. If you use soft suitcases, linking the zippers with plastic cable ties is a good security measure; you will be instantly alerted that your bags have been opened if they are missing, and they prevent zippers accidentally sliding open.
