There were no body scanners at airports on Sept. 11, 2001.
No rules about liquids in 3-ounce containers. No taking off shoes and walking barefoot through a guarded checkpoint.
But after 9-11, airport security changed dramatically and rapidly. At Dallas/Fort Worth Airport alone, $300 million has been spent on security upgrades in the past decade.
Today, passengers must show government IDs that match boarding passes and undergo different types of screening before heading into the gate area.
Many have complained that their privacy has been compromised either by overaggressive pat-downs or invasive body scanners. Yet even as security systems continue to evolve in response to passenger complaints and ongoing threats, coping with airport security has become a permanent part of life for U.S. air travelers.
“There is the hassle factor in the airport experience,” said Bill Swelbar, an airline researcher at the Massachusetts Institute of Technology. “Security is tighter, lines are longer and we now have the TSA that is not going away, and that is a cause from 9-11.”
