Keeping your Tile connected to Bluetooth while inflight
Tile is a low-powered Bluetooth device. While most airlines permit Bluetooth use, we recommend you consult with the airline's specific policies regarding Bluetooth devices to avoid any complications.
If the airline permits Bluetooth technology, switch your device to Airplane Mode but keep Bluetooth on.
Also, feel free to check out this blog post about real users who have used Tile to keep track of their luggage.
Tile battery safety
Tiles use non-rechargeable lithium batteries, similar to those used in wrist watches or key fobs. You can pack them in both check-in and carry-on luggage. They are not restricted by aviation or transportation authorities. For more information about what you can pack, visit the TSA website.
