If you travel with a Samsung Note 7, you’re likely on the honor system when deciding whether to use or charge the device during a flight.
The Federal Aviation Administration said Thursday night that because of recent fire reports involving the smartphone, passengers shouldn’t use or charge one or stow one in checked baggage.
It is very unusual for the FAA to warn passengers about a specific branded product. The agency said it acted after Samsung reported the incidents involving the phones.
The three biggest U.S. airlines – American, Delta and United – said Friday that they were studying the FAA warning but it was unclear how they would make sure that passengers keep the Samsung devices powered off.
A Delta Air Lines spokesman, Morgan Durrant, said “For now, we are studying this.”
