I'm just curious: is there anything to prevent me from making up a name, buying a ticket using that assumed name, and then telling the airline at check-in that I have no ID or forgot my ID? the airline marks your boarding pass "SSSS". Then it seems all TSA does is ask why you have no ID, ask if you have any other identifying ID, and then does a secondary. But do they ever call the police to verify your information, and see if you are in the driver's license system...to make sure you are not flying under an alias?
