There is a difference between doing Type Rating and doing a LT. Same as doing MCC JOC in todays era. A good JOC costs also 10-13K in CTC. For a few more K I had my TR incl. Base Training.
Line Training is a whole different story. You fly with actual PAX. Pax bring revenue. For that you should get paid which is in many situations is NOT the case. No salary or very little salary while flying with PAX. Instead you pay a big sum of money to be allowed to sit in that RHS. You see the difference Council?
