Just to be clear, there is no evidence that GE is the cause of the SSSS, just that it is not creating exemption from SSSS in airline systems setup to accept known traveler numbers. The irony is that a redress number would probably nix the SSSS, but not a PASS ID.
It is just how [in]SecureFlight is setup. The proper tweak would to be for SecureFlight to take PASS IDs where offered and add that to the protocol for exemption from SSSS-- right now, an SSSS generated due to PNR factors is not nixed by a PASS ID, but can be by a valid redress number. It is just a matter of putting some lines of code into the SecureFlight software that no one has bothered to put in yet.
