Yes, you are absolutely allowed to place an Apple AirTag in both your carry-on and checked luggage in 2026. This was a point of confusion for a few years, but the FAA (Federal Aviation Administration) and the TSA have explicitly stated that these tracking devices do not violate safety regulations. AirTags use Bluetooth Low Energy (BLE) and are powered by a tiny CR2032 lithium coin cell battery, which contains less than 0.3 grams of lithium—well below the threshold that would categorize it as a "dangerous good." Consequently, you do not need to worry about them being confiscated during the screening process. For travelers, this is a high-value security measure: if your bag is mishandled or lost by an airline, you can use the "Find My" app to track its precise location, often pinpointing its whereabouts before the airline's own baggage system updates. Just ensure your AirTag is tucked into a secure pocket inside the bag to prevent it from being accidentally knocked out or removed.
