Tony Tyler spoke at an international conference in the United Arab Emirates where airline executives warned that unless there's a major overhaul of security measures, terminals will become overwhelmed, and passengers will become even more disgruntled.

Tyler is optimistic that instead of screening every passenger the same way, there will be a system based on individual passenger risk. It's a concept that the industry hopes will be tested at a handful of airports starting in two years.

The head of the U.S. Transportation Security Administration told the conference that passengers who are "willing to share a little more information" ahead of time will have a "much better experience" at airport security.

Airline executives said Tuesday, Oct. 16, 2012, at a global aviation conference that Airport security needs to undergo a radical overhaul or else passengers will become further disgruntled, lines will grow and terminals will be overwhelmed.

"We simply can't cope with the expected volume of passengers with the way things are today," said Tony Tyler, director general and CEO of the International Air Transport Association, the airlines' trade group.
