Purdue Pilot,
Any pilot that is authorized to ride in the actual cockpit jumpseat must have their information validated at the time of check for the flight they wish to jumpseat on. Most airlines have some form of computer system which can verify employment etc. for anyone in that system. UAL can verify info for UAL and their express carriers, but not for AA, within their own computer system. CASS is an independent database which verifies employment for any company participating in the database. It apparently costs a bit of money to join which is why some companies may not be too eager to sign up. Also the TSA was dragging their feet to get it all approved, which just happened officially this summer some time. Most of the majors participated in a test phase and are CASS approved now. Some regionals are as well. Hope this helps.
