I've traveled a lot and our luggage always arrived, although sometimes 2 or 3 days later.
The latest news items, along with our upcoming flight with a transfer in LHR, are making me a little nervous though.
I'm an Android user so AirTags are of no use to me. In this post the only alternative discussed is Tile. Is nobody using other devices, there seem to be plenty of them when I search on Google. Some of them also specifically aimed at luggage.

I just wonder if a device lacking a GPS can properly indicate your bag's location if it's lost in a hall filled to the brim with suitcases. I'm not sure if a Tile user will get close enough to my lost bag if it never makes it to a luggage belt but instead gets lost in the basement at LHR.
