Record numbers of airline passengers will soon be taking off for spring break, expecting to find fun.

But first, they'll have to get through the Transportation Security Administration screening at the airport. Definitely no fun there.

Both the TSA and Airlines For America (A4A), an industry trade group, say travelers should brace for long waits in epic lines. "It's a very serious concern," A4A Senior Vice President Sharon Pinkerton said on a conference call with journalists Wednesday.

On a chilly afternoon in south Georgia, more than 100 Transportation Security Administration trainees are huddled together on metal bleachers overlooking a field. They're watching an explosives instructor demonstrate what can happen if they don't do their job well.

"All right, confined smokeless powder in three, two, one."

BOOM!

The trainees (and an observing reporter) jump, startled by the explosion 100 yards or so before them.

More blasts follow, with different explosives. The lesson for these new hires? That the consequences of a mistake are deadly.

Federal officials say they're delaying a policy that would allow passengers to carry small knives, bats and other sports equipment onto airliners.

The Transportation Security Administration said Monday that the policy change has been delayed to accommodate feedback from an advisory committee made up of aviation industry, consumer and law enforcement officials.
