Aviation Royal Jordanian bans some electronic devices from U.S. flights By Robert Silk / March 20, 2017 Share 1 -- Citing a U.S. government mandate, Royal Jordanian Airlines said that passengers traveling to and from the United States won't be allowed to carry on electronic devices such as laptops, tablets, cameras and DVD players. "Following instructions from the concerned U.S. departments, we kindly inform our dearest passengers departing to and arriving from the United States that carrying any electronic and electrical device on board the flight cabins is strictly prohibited," the carrier said in a tweet Monday afternoon. Cellular phones and medical devices will be excluded from the ban. The rule applies to Royal Jordanian's Amman-New York, Amman-Chicago and Amman-Montreal-Detroit service. The Department of Homeland Security declined to comment on the Royal Jordanian tweet Monday, and wouldn't say whether it relates to a larger new security measure. "We have no comment on potential security precautions, but will provide an update when appropriate," spokesman David Lapan said. In July 2014, the TSA implemented a measure under which security officers at foreign airports asked passengers to power up electronic devices prior to boarding U.S.-bound flights. The agency made the move out of concern that terrorists could hide explosives from screening devices. It has since dropped the measure.
