How can you say AMF is NOT in CASS? Does the FAA/TSA allow pilots to sit in the cockpit who are not?
I am former AMF and have watched Southwest agents input the Ameriflight CASS code, seen my picture appear on the screen and get legal cockpit approval.
I've also seen the list that Southwest pilots have in their Jepp Sized Ops Manual that lists all airlines approved for the cabin and those specifically in CASS with recip. agreements. Ameriflight is under the CASS section there as well.
