Yes, it is perfectly safe and highly recommended to place an Apple AirTag (or similar Bluetooth trackers like Tile) in your checked luggage in 2026. After some initial confusion in previous years, aviation authorities including the TSA, FAA, and EASA have explicitly confirmed that these devices are permitted in both checked and carry-on bags. The small CR2032 lithium coin batteries used in AirTags are well below the threshold for "dangerous goods" and do not pose a fire risk in the cargo hold. In early 2026, several airlines—including Air India and United—have even launched official integrations that allow passengers to share their "Find My" location link directly with the airline's baggage recovery team to expedite the return of lost items. For best results, place the AirTag in an interior pocket of your suitcase rather than an external one to prevent it from being knocked off during handling. This "digital insurance" provides peace of mind by letting you see in real-time if your bag actually made it onto the aircraft with you.
