While waiting in line, just about everyone bitches and moans about the airport security screening process. But of the over 500 million fliers this year, only 12,000 have filed official complaints with the Transportation Security Administration. The rest of us just air our grievances on our blogs.

The number one complaint this year is that the TSA screeners mishandle personal property. This includes when items get damaged in the screening process, as well as lost and stolen. A TSA spokeswoman insists that the agency takes theft very seriously, and that the "TSA has let officers go who've taken 50 cents out of a bowl." It's good to know they care -- but we're not impressed with how long it took them to catch one agent who had stolen over $200,000 worth of travelers' property.

The second largest complaint the agency gets is reports of rude treatment. Most TSA agents I've crossed paths with recently have been perfectly friendly, but it just takes one meanie to leave a long lasting bad taste in a traveler's mouth -- and most security lines have at least one meanie, I've noticed.

If you have complaints for the TSA, they urge you to share your comments on their official website, www.tsa.gov. You can also call with complaints or fill out comment cards at the airport.
