gonyon, not sure what you mean call to list as nonrev on Southwest. You are either a pilot jumpseater or a ZED nonrev. If you have a ZED then you already get a SW non rev listing with it. As a pilot jumpseater I believe it used to be you could call SW and create a jumpseat listing on the phone and they would give you a 6 digit confirm code. But I do believe now one has to go to the desk/gate and ask to jumpseat.
