In Paris, soldiers patrol at Charles de Gaulle Airport last week. French airports have reportedly agreed to a new TSA policy requiring electronic devices to be powered up before they're allowed on U.S.-bound flights.
A graphic released by the TSA earlier this year announced coming changes to the agency's Prohibited Items List, which it said would allow small knives. The TSA now says those items will remain banned from carry-on bags.
A sign informs travelers about Millimeter Wave Detection technology used in full body scanners at Midway Airport in Chicago. The scanners produce less-revealing images than those that use X-rays.
