According to the FAA, Apple AirTags are permitted in checked baggage

The clarification comes after concerns that Lufthansa might prohibit active AirTags in luggage. There were fears that the German airline would interpret International Civil Aviation Organization (ICAO) guidelines to prohibit any lithium-powered tracker that cannot be turned off, including AirTags. There was speculation that Lufthansa wanted to prohibit the tags in order to conceal problems with lost luggage and other air travel issues. However, the ICAO can only issue guidelines; it is up to officials to adopt and enforce rules, and there are none for these devices in either Germany or the United States.
