In the US, the first "pay for training" concept was initiated by Flight Safety Inc and Comair, a Delta Airlines regional partner. It is an interesting fact (to me) that the training, which had cost about the same as a B-737 or DC-9 (maybe F-100 etc) jet type rating, was for left seat turboprop simulator training and was created so that the successful trainee was not allowed to have the type rating, thereby preventing him/her from having a much more competitive resume/C.V., which theoretically could have allowed a few Brasilia First Officers to jump ship. . .. .What a deal for the trainee, paying the about same price but receiving no rating.
