The TSA's own site claims they are subject to the Privacy Act, but individual screeners seem quite averse to any sort of compliance, IME. And the statement on the TSA site is full of weasel words, like "will provide you with notice of the collection in appropriate circumstances" (emphasis mine), so YMMV as to their actual compliance.
