It’s not entirely clear whether or not Lufthansa is banning the use of AirTags in luggage stowed on their planes. It seems, however, they at least don’t like the idea.
I’ve been using AirTags in airline luggage since AirTags first showed up, and I plan on continuing to do so. Apple’s tiny tracker confirms for me when my luggage gets on the plane and then later gets off my plane. AirTags also come in handy to know exactly when my luggage makes its way to baggage claim and confirm that it doesn’t leave baggage claim without me.
I keep my luggage AirTags on the inside of my luggage, and I’ve never had a problem with reception. They come in very handy when traveling.
