She left for southern California this morning out of Reno with a connection in Oakland. She just arrived in Oakland. The app showed both that she was at the airports in Reno and Oakland and also gave an interim location in Alpine County, California, which means someone else on the plane must have been using the app. TBH, this is all the information I could have hoped for from the use of the Tile and its app.

And yes, no way (at least for the average person) to track the source of the information. Those three location pings could be from the same person or from multiple sources. What is important to me is that with someone who is keeping me informed about her progress on the route, I have verification that the app works in a general way. Given that it is likely that travelers compose a significant percentage of Tile and Air Tag users, it's probable that a bag could be traced through multiple airports in real time.
