Yes, smart tags like Apple AirTags, Samsung SmartTags, and Tile trackers are fully allowed in checked luggage as of 2026. This was a point of confusion in previous years due to FAA and EASA regulations regarding lithium-ion batteries in the cargo hold. However, the regulatory bodies have clarified that because these devices use very small "button cell" batteries (like the CR2032) and have very low power output, they do not pose a fire risk. In fact, most major airlines now openly encourage their use as a backup for the airline's own tracking systems. They are invaluable for peace of mind, allowing you to see if your bag actually made it onto the plane before takeoff. Just ensure the tag is securely tucked inside a pocket or a dedicated luggage holder so it doesn't get knocked out during the rough handling process.
