10 Biggest Bonehead Moves at Airport Security

5.) Wearing a Welterweight Championship Belt

Minimizing metal has been the airport-screening stereotype for ages, but it seems even to this day as though there's always someone who has to go through the screening process over and over again, the system beeping each time, the person emptying wallets and taking off belts each time.

It's best to have keys, loose change and other items in a bag that will go through the X-ray machine, rather than carrying them with you. Even underwire bras can set off the metal detector, if it's ramped up to more sensitive settings.

6.) Leaving Your X-Rays at the Doctor's Office

Anything unusual about your body may require evidence. If you have a metal plate in your head or metal pins in your ankle, for example, it might be best to bring evidence like X-rays to demonstrate that, just in case those things trigger the alarm. And if it does mean you get picked for secondary screening, "just tell them as much as you can up front" about your pacemaker, insulin pump or other medical device, Payne says.

7.) Keeping Your Laptop Under Wraps

You know this one but you keep ignoring it. Laptops need to be in an easy-to-reach spot because they absolutely must come out during screening, and run through the X-ray machine in a separate bucket.

The best option is leave the laptop at home if the boss lets you. But if it must come along, keep it in a place where it can easily be taken out and put back in.
