Leaving a regional for the ACMI stuff led me down a path that quickly got me into steady cargo job. Great experience from the ACMI stuff. Glad I don't do it any more but I wouldn't be where I am without it. ACMI was tough on the family, but for me it took effort to balance everything out and then life was decent. Good luck at Atlas and enjoy the new world. You will be surprised about how little you know about flying...and I say that with a smile because that was my personal experience.
