Story time. My wife and I were vacationing in Portugal last summer. She left her purse in a uber car on the way to the airport. The driver found the purse and dumped it after taking 20$ and some costume jewellery. We tracked it to an abandoned parking lot later that day using an AirTag and we ended up finding it using the Location app. We have AirTags in every bag now and we change the batteries on a schedule.
All my bags also now have airtags. I was at Sydney airport lost baggage area a few years ago waiting for a bag I'd found was there after hours of speaking to the airline and airport. Another gentlemen there told them that his item was there. They'd been evacuated from a plane in New Zealand a month before and left his iPad in the seat pocket, and had tracked it back using Find My to Sydney. He travels internationally multiple times per month and said airtags were the best thing he owned.
I've since added them into all my cars, bags and a few honeypots embedded into high value items that might be stolen.
