Once again, you could have provided the airline that does and proved me wrong.  But you didn't.

AIRLINE instructors are line pilots.  They are in the same class/craft as non-instructors, because they are all in the line pilot (flightdeck) class/craft

AMC instructors are not line pilots.  They are and were given a separate and distinct class and craft from the line pilots.  The union had a conniption fit if an instructor flew the line!   Some instructors didn't even have a Class II medical.  They are not the same class or craft!

So, you are 100% incorrect here!
