I'll add another vote for airtags as a baggage tracker. We were recently in the UAE and when we arrived none of our bags showed up. We were able to see where they were and eventually had to pick the last one up at the Abu Dhabi airport since the airline never delivered it for unknown reasons. We knew right where it was and saw that it had been sitting at the airport all day and they never picked it up to deliver it. It only took 3 days, but we ended up with all of our luggage eventually.
The airtags will only ping off of Apple devices, so they definitely work better in countries/areas with a high amount of Apple phones.
