DL flow up is not a thing anymore, I think the last guy flows up in January.
Basically they said NO to any renegotiation of compensation/schedule/duties. I am unaware about a replacement, but
I'm sure they found someone fairly quickly...there is always an unending stream of young pilots looking for a gig that pays good money, and like many Part 91 owners, they paint a pretty rosy picture.
Regionals are generally not eager about their pilots flying outside. FOMs differ, some want an LOA from chief pilot, all require you to report outside flying. Yea, at 85/hr month guarantee I'm sure you cut it close if you fly much.
