The majors do not care what type the TPIC came from, they care about you being a 121 captain and the responsibility that comes with.

As a matter of fact I could argue that a 200 captain has more experienced than a 175 captain, it’s definitely a bigger challenge. The airlines want someone who has decision making experience, knowing when not to go, dealing with the changing environment - airlines as a whole could care less about wing mounted turbine time.

Just because you are typed in an airplane doesn’t mean your not going through the same training program as everyone else at intial. I give you this, you know where the engine start switch is already and you might be easier to train systems and handling to. But that won’t be then difference between choosing you for the job over another candidate.

Hell you could be harder to train because you already do it “X” and the new airline wants it done “Y”.
