I am flying from Toronto to Paris (Charles de Gaulle) in just over 24 hours, en route to Edinburgh. I have a Phantom 4, its controller, minimal accessories and two batteries that I have stored in the original grey styrofoam shipping box (once the price of the ThinkTank Helipak goes down I will be all over that!). I am flying with Air France for both flights and since I have enough space in my checked luggage, I plan to check as much of the drone and its hardware as possible. With this I have a few questions: The controller has a lipo battery within, is it allowed to be placed in checked luggage? Do the drone batteries have to be discharged? To what percentage? The Air France "Conditions for transporting batteries and lithium batteries" (https://www.airfrance.fr/common/image/pdf/en/Bagages_batterie_lithium_en.pdf) document says that lipo batteries under 100Wh can be placed in checked luggage so long as they are contained in a device. I'm assuming the drone would qualify as a "device," therefore can anyone attest to this being true? Regardless of if I have one drone battery or two in my carry on, do they have to be placed in plastic bags and terminals covered with electrical tape as many have mentioned? Thank you in advance for any help and if there are any other precautions I am missing, please do let me know!
