Travelers and content creators who rely on Apple’s AirTag to track luggage often wonder if these small tracking devices are permitted in checked bags, especially given strict airline policies on lithium batteries. According to TSA guidelines referenced in recent reporting, the key concern revolves around battery type and watt-hour rating—factors that determine whether an item can fly in cargo holds. While airlines typically restrict spare lithium batteries due to fire risk, installed batteries in consumer electronics like AirTags are generally allowed if they meet specific safety thresholds. The AirTag uses a user-replaceable CR2032 coin cell battery, which falls well below the limits that trigger restrictions for larger lithium-ion batteries commonly found in power banks or laptops. As such, TSA and most international aviation authorities permit AirTags in both carry-on and checked luggage when the battery remains securely enclosed within the device. This distinction is crucial for creators who frequently check gear-heavy bags containing cameras, drones, or lighting equipment and want real-time location tracking without risking confiscation or delays. However, experts advise ensuring the AirTag is properly sealed and not loose in the bag, as exposed batteries could still raise security concerns during screening. For added peace of mind, some creators opt to place AirTags in carry-ons despite permissibility in checked bags, minimizing any chance of mishandling. Ultimately, current regulations support using AirTags as a reliable tracking tool for checked luggage, provided the device remains intact and the battery is not removed or loose—a simple but vital detail for anyone moving between shoots, festivals, or international assignments where lost gear can derail a project. Always verify with your specific airline, as individual carriers may impose additional restrictions beyond TSA baselines. Safe travels—and never lose your kit again.
