The Transportation Security Administration is requiring passengers at some overseas airports that offer U.S.-bound flights to power on their electronic devices, the agency said Sunday, July 6, 2014. It says devices that won’t power up won’t be allowed on planes, and those travelers may have to undergo additional screening. (AP Photo/Eugene Hoshiko, File)
