Skywest does not hire DCA types with below minimum times. We have no formal relationship to DCA, or any other flight school for that matter (you may see more from one school or another, but that's a function of pilot networking not agreements). We have no "package deal" with Delta with regards to the pilots we hire. We only hire those pilots who meet our minimums of 1000/100/100.
That's been my experience in the last couple years being involved with pilot hiring- things could have been and probably were different before my time.
