airline passengers go through security

In this Aug. 3, 2011 photo, airline passengers go through the Transportation Security Administration security checkpoint at Hartsfield-Jackson Atlanta International Airport, in Atlanta. The TSA has expanded its new passenger screening program to make check-in easier for certain travelers. That means more people will be able to keep on their shoes, jacket and belt through the security lane. But it’s still only available to a certain frequent fliers, or those who apply for special screening programs, which cost up to $100.(AP Photo/Erik S. Lesser)
