Oh and to answer your question- yes. There are a FEW select corporate pilots that get travel benefits on a very small number of airlines. These guys work for corporate flight departments that have established part 135 certificates (for whatever reason). They can usually only travel on carriers that have "open" 135 jumpseat agreements (I believe that Chautauqua is one of those carriers that allows any 135 pilot to jumpseat in the back). No CASS agreements for anybody outside of the 121 world.
