On July 2, 2014, Secretary of Homeland Security, Jeh Johnson, directed the Transportation Security Administration to implement enhanced security measures in the coming days at certain overseas airports with direct flights to the United States. DHS states it will work to ensure these necessary steps pose as few disruptions to travelers as possible. Airports have not been named, but major European hubs such as London Heathrow, Frankfurt and Paris Charles de Gaulle are believed to be among them.
All electronic devices are screened by security officers. During the security examination, officers may also ask that owners power on some devices, including cell phones. Passengers are being advised to keep devices charged and be prepared as these can be checked at security and/or the gate prior to boarding. Powerless devices will not be permitted onboard the aircraft. The traveler may also undergo additional screening.
All countries are complying with US government recommendations for increased security measures, which are believed to be the result of intelligence reports of a credible terrorist threat.
Transportation Security Administration (TSA) adjusts security measures to ensure that travelers are guaranteed the highest levels of aviation security. See article on TSA site.
