Perhaps
In the past that was true I do not know about now. With the shortage of qualified crew as the airline grows, they will need to pay to attract decent people. Just my opinion but, getting effectively two weeks of training via a huge amount of emails, unpaid, will scare people off. Plus, before you ever show up or even get an ID, you get these emails about doing all this training in ten days or less. And it doesn't stop there. Delta or any major or even the best regionals-maybe but some charter outfit trying to grow, and a lot, plus the Eastern mess, it will convince people to perhaps look somewhere else.
