10 Biggest Bonehead Moves at Airport Security

8.) Running Late -- and Running Into a Long Line

If you're tardy time and again, at least check in advance to see how long the security lines are at the airport. The TSA provides wait times online, as well. Individual airports often post wait-time information; the Denver and Boston airports, for example, have information about wait times on their homepages.

9.) Being Unprepared for a Patdown

Not everyone gets patted down, but if you're selected for the extra security screening, it can be a little creepy.

Patdown searches are supposed to be done by someone of the same gender "except in extraordinary circumstances," the TSA says, and you can request to be taken into a private area for the procedure if you prefer.

10.) Playing Santa Before You Get to Grandma's House

The TSA can inspect anything it wants in your bags, so if you wrap gifts first you run the risk of having that hard work undone by security personnel.

Some people take the risk and do it anyway, but don't be surprised, especially if the gifts look unusual in the X-ray machine, when the security workers want to unwrap them.
