Content overview: “TSA Rules on AirTags in Checked Luggage: Are Tiny Batteries Allowed?”. As travelers increasingly turn to Apple AirTags to track their luggage, confusion swirls around whether the TSA permits these small trackers in checked bags. Airlines and the TSA generally prohibit loose lithium batteries and power banks in checked luggage due to fire risk, but the rules for devices with installed batteries—like AirTags—are less clear-cut. The TSA's official stance allows devices containing lithium batteries in checked bags if they are installed and protected from accidental activation.
AirTags use CR2032 coin cell batteries, which are lithium metal and contain a small amount of lithium. While the TSA does not specifically name AirTags, their guidance suggests they are permitted. However, individual airlines may have stricter policies, and some international carriers have banned AirTags in checked luggage due to battery concerns.
