I believe CS has some limited agreements, but I know NJA has none and I don't know about any others. I know some pilots at NJA who do jumpseat from time to time, but the carriers that will allow it are few and far between. NJA does have a lot of retired airline pilots who retain pass privileges with their former carriers, but that isn't really jumpseating. Most fractional pilots will get a lot of airline miles going to and from the airplanes they fly themselves. At NJA most pilots earn between 4 and 6 domestic tickets a year. I miss jumpseating, but that is about the only thing I miss about the airlines.
