The utility of putting a traceable tag in your bag completely escapes me.
Imagine calling the airline, your bag has been lost, and you can see that it is in a building in city X. You can even see it on a map.
Now how does that help? Do you think the airline tracing system has a way to absorb that information, even if they believe you?
Are you going to fly there and break into the building that you think holds your bag somewhere?
