Storytime: After traveling last summer carry-on only, and being a person who tries to carry on whenever possible, I finally bought a couple of Apple AirTags during Black Friday sales. And I am SO grateful I did. My normal carry-on bag was too big to fit the Lufthansa luggage requirements so I had to check my bags for a December 2022 trip to Vienna and back from Prague .
I pulled up the app on my phone and saw that yes, my backpack AirTag was indeed with me, but my suitcase AirTag was still in Germany . The AirTag also helped me track FedEx's delivery of the suitcase to my parents' house, where I was spending the holidays immediately after my Europe trip ended. I was even able to see it on a highway less than an hour's drive from my parents' house. TL;DR: I think AirTags are very much a worthwhile investment if you travel a few times a year. And I'm not the only one who thinks so.
