I believe the sign on bonus is if you're typed in the CRJ or ERJ, I would ask for confirmation from recruiter on 175 since I believe the incentive for the company is a shorter course for new hire, but no shorter course yet exists on the 175, at least not till we get AQP which I was told would be September or October...but they did tell us we'd have it 03/2015 too so who knows haha
