You are commercial pilots,dont pay for line training.You should be paid for that.If you are guys that like flying planes as a hobby then continue paying.I know for a fact that in the airline that i work for and at a lot more airlines,if they see on your cv that you paid for the line,they will never call you for an interview.Big airlines need professional pilots,not people who are not the right kind for the job and they just pay to get it.
Beware of that guys.Good luck to all of you.
