Yes, that does help. I'm interested in doing some 135 on demand operations as well as scheduled service within the mid west and east coast regions. I'm looking at the feasibility aspect as well as the cost. You're saying that the same airplane couldn't do both, right since there would be two separate op specs? I'd have to operate two different airplanes then one for 135 and one for 121? Correct me if I'm wrong, but new carriers can no longer operate under scheduled 135.
