What happens if TSA finds something in your checked bag?

The TSA will collect your prohibited item and dispose of it according to Government Services Administration rules. Normally, this means your item will be thrown away, but some airports donate useful items to community organizations, such as schools.

Why does my checked bag always get searched?

Most airports screen checked bags electronically, by X-raying the bag or examining it for explosive-chemical residues. If these electronic means detect anything suspicious, inspectors hand-search the bag. At a few airports that lack detection machines, your bag probably will be hand-searched, among other methods.
