I am currently a dispatcher for a 121 carrier, but am thinking of going to a 135 company. I was wondering if any licensed dispatchers who work for a 135 carrier can jumpseat with 121 carriers? I know you don't have to have an FAA license to work for 135, but I figured those that do can still use their jumpseat privelages on 121 carriers. If anyone has any comments on this please can you help me. Thanks
