" I know that we are 1.5 years into a 5 year contract. With that being said, there is no way we will have a new contract 5 years from now. Look how many years it took to get this one."

This may be true. However, Atlas may actually have a contract sooner than 5 years from now. If management senses that the current contract is (or might soon be) causing enough of a problem with retention and/or hiring, they could open negotiations earlier and offer better contract terms before the 5 year period is up. That has happened at other airlines.

Do I think that is likely? I have no idea, and I don't think anyone else does, either. The hiring situation is VERY complicated, and depends on so many factors outside the control of any airline management or pilot group, that it is very difficult to predict how the hiring boom will affect specific companies.
