An Apple AirTag for tracking your luggage
When my normal carry-on bag was too big to fit the Lufthansa luggage requirements (and BOY, do they check that!), I had to check my bags for a trip to Vienna from Prague with a layover in Frankfurt. My bag didn’t make it onto the plane in Frankfurt, and once I landed, I pulled up the app on my phone and saw that my suitcase AirTag was still in Germany. (The photo here is from an Amazon review, but you get the gist.) The AirTag also helped me track the ensuing delivery of the suitcase; I was even able to see it on a highway less than an hour’s drive from my parents’ house. 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.
