That was the lesson learned last year when a Florida airport worker was arrested and charged with two counts of grand theft. Sheriff's deputies found stolen luggage in his home and he admitted to removing an AirTag from the luggage, which authorities never recovered.

Stripping an AirTag from luggage is almost too easy. An AirTag that isn't with its owner for a period of time makes a sound when you move it.
You can also go to "Find My" to see if there's an unknown AirTag nearby.

The bad guys will not know what it is, allowing you to recover your lost luggage if it's stolen.
For a higher level of security, consider upgrading to a GPS tracker like
Pebblebee.com
or
Gego.io
