> If you closely observe the TSA process, they check the ID with the name on boarding pass. This is revenue management service for the airlines. The rationale for checking name match is there there is a separate part of the TSA process which identifies high-risk and prohibited individuals, and that works on name matching. That has already been completed based on the name on the boarding pass, so using another persons boarding pass/false name would bypass those checks. You could still bypass the airline's rules by entering with a ticket for another flight in your name (refundable or cheap) and using someone else's ticket at the gate. Couldn't check a bag, however. (although I inadvertently bypassed the checked bag-ID match at DCA last time)
