Be sure your luggage has your identification inside, along with your i.d. tag on the outside. (External tags can sometimes become separated from your bag.)
When I travel on long tours, I have a 2-sided information sheet pinned to the inside of checked bags. One side has contact info (usually the address and phone number of someone back home who knows how to reach me). The other side has my itinerary.
If my luggage is lost en route, there’s a better chance of locating me during my adventure, helping ensure that my bags don’t make it home before I do.
