If you haven’t yet returned your Note7, you might want to consider doing that now that you won’t be able to fly with it.
The United States Department of Transportation has issued an emergency order to ban all Note7 units from all flights in the US. The ban will become effective October 15, starting at noon ET. This means you will not be allowed to carry a Note7 on a flight within the US, or originating in the US, or going to the US.
Not even if it’s turned off. Not even in carry-on or checked luggage.
