On: Lufthansa has not banned AirTags

[layer8]

The problem is not (only?) the broadcasting. The problem is the lithium battery used in a non-switched-off device.

Has a CR2032 ever been the cause of an actual fire?

[layer8 → m-p-3]

Maybe not (who knows), but the relevant aircraft transport regulations apply to all types of lithium-based batteries.

[nonethewiser → layer8]

Not really. 2032's power most watches. There are far more watches than air tags. Why didn't they ban them?

[layer8 → nonethewiser]

They (Lufthansa) didn’t ban AirTags. When asked about whether AirTags are allowed in checked luggage, they cited the pertinent ICAO regulations. They might do the same when asked about powered-on watches with lithium batteries in checked luggage.
