Can You Put an AirTag in Checked Luggage? Rules and Real-World Use

You clip an AirTag inside your suitcase, hand it over at check-in, and then a small doubt creeps in. Is a lithium battery allowed to sit powered on in the cargo hold, or did you just hand the airline a reason to pull your bag aside? Here is the direct answer, the rule behind it, and the one habit that actually matters more than the legal question.

The short answer: yes, and here is why

An AirTag in checked luggage is legal. The FAA confirmed this explicitly at the end of 2022, and IATA's dangerous goods guidance treats it the same way: devices using a lithium metal coin cell with 0.3 grams of lithium or less can stay powered on and transmitting inside checked bags. An AirTag's CR2032 cell holds roughly 0.1 grams of lithium and about 0.7 watt-hours of energy. That is nowhere near the 100 watt-hour threshold that restricts laptops and large power banks, and it sits well under the coin-cell limit too. Tile trackers and Samsung SmartTags use similar coin cells and fall under the same exemption. You do not need to declare it at check-in, and TSA does not treat it differently from a wristwatch battery.

Why the confusion started in the first place

The doubt has a real origin. In October 2022, Lufthansa posted that it was banning active AirTags in checked bags, citing ICAO lithium battery guidance. The airline reversed the decision three days later after Germany's federal aviation authority reviewed the actual battery size and confirmed that low-power tracking devices posed no safety risk. The FAA's formal clarification followed in December that year, spelling out the 0.3-gram threshold by name and stating that Apple AirTags meet it. The underlying rule was always written with laptops and multi-gram lithium-ion packs in mind, not a coin cell the size of a fingernail. Lufthansa's initial tweet just applied it to the wrong category of device, and the correction stuck. No major airline currently bans AirTags, and a growing number, including American and Singapore Airlines, now let passengers share a tag's location directly with baggage services to help trace a delayed bag faster.

The exceptions worth checking before you fly

The FAA and IATA baseline is permissive, but it is a floor, not a guarantee that every carrier and every country reads it the same way. Individual airlines can still apply stricter interpretations of dangerous goods rules, and some countries' customs authorities take a harder line on transmitting electronics in general, independent of the battery question. If you are flying an airline you have never used, connecting through a country with unusually strict electronics rules, or traveling somewhere with limited information available in English, a two-minute check of that airline's baggage policy page is cheap insurance. For the broader mechanics of how these trackers actually report a location once your bag is airside, our piece on whether luggage trackers really work covers the network side of the story in more detail.

Where to actually put it in the suitcase

Legal is not the same as useful. An AirTag zipped into the easily reached front pocket of a checked bag is the first thing a baggage handler, a thief, or an overzealous inspection removes, whether by accident or on purpose. Push it deeper: inside a rolled-up piece of clothing near the center of the bag, tucked into a shoe, or clipped to an interior strap if your suitcase has one. The goal is a spot that survives a bag getting opened and repacked without falling out or catching an eye. A basic bluetooth luggage tracker works the same way regardless of brand, so the placement habit matters more than which tag you buy. And keep the essentials, medication, chargers, anything irreplaceable, in the bag that stays with you; our guide to carry-on versus checked luggage walks through exactly where that line sits.

If the bag still goes missing

A tracker only tells you where the bag is, not how to get it back. You still have to file the report at the airline desk before you leave the airport. If that happens, our step-by-step guide to a lost bag covers what to bring to that counter and what the airline owes you while you wait.

Pack the AirTag, place it deep in the bag instead of the outer pocket, and stop worrying about the legality. The rule has been settled since 2022. The only thing worth double-checking is a specific airline's page if you are flying somewhere unfamiliar, and even that takes less time than the walk to your gate.
