I am pretty familier with US jumpseat rules, and I can tell you that CX can do absolutly nothing to get in the actual jumpseat. As others have pointed out, getting on a seat using the jumpseat list will be next to impossible. Most airlines give those using a pass a higrer priority than a jumpseating pilot, so you have a better chance of getting on using a pass. I am all for trying to get all airlines on jumpseat lists, but dont think that just because you are on that list your commute will be easier.
