You must do this to get pass security and the TSA. You must show some sort of documentation. Once you are in you go to the gate and sign up so more than one hour in advance.
Since Ameriflight is CASS approved you may be able to fly or jumpseat on other airlines, but it depends on the airline and if the captain is willing to accept you
This has tightened up considerably after 9/11. It is safe to assume you will not get a jumpseat if you are not on the list.
