BuzzFeed writer Elizabeth Lilly uses these when traveling:

“Story-time: 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 (and BOY, do they check that!), so I had to check my bags for a December 2022 trip to Vienna and back from Prague (with a layover in Frankfurt). My bag didn’t make it onto the plane in Frankfurt, and once I landed in Newark, New Jersey, 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.”

Promising review: “I now always use my AirTag when traveling to put in my checked luggage to make sure it doesn’t get lost. It’s very easy to check on.” —P Hampshire
