Ameriflight is not an ARINC CASS carrier. ARINC publishes a list of CASS carriers that have signed contracts with ARINC and Ameriflight is not on that list. However, I spoke with ARINC on this, and the Director there told me Ameriflight had developed some sort of program that their POI, and TSA bought off on, thus allowing them cockpit access. I don't know if it is routed the same way or not, and I don't know the details as it is really none of my business. My understanding though is Ameriflight does have the ability to gain access to cockpit jumpseats.....I do not know if that is only with certain types of computer systems (i.e SWA has a very unique system when it comes to the software they use for gate agents for Revenue, non revenue and CASS) or if it available to all....I guess I could ask ARINC this question, but SkyWest does not have an agreement with Ameriflight so I am not that motivated to do so.
