The simple fact of the matter is republic et al does this to recoupe some of their tax liability. If it was such a burdensome expense to them, why don’t they develop their own in house ATP-CTP? They certainly have the means to.
Someone please quote me the FAR that says an applicant must have completed an ATP-CTP course to be hired at a 121 carrier.
For that matter, show me the FAR that prohibits a 121 carrier from hiring a student pilot and training he or she from pre-solo to ATP,(insert type rating).
At my company, I was hired, did indoc, then ATP-CTP. I accrued seniority and got min guarantee while in ATP-CTP. I only paid tax on my regular pay.
