They are actively trying to help the top 25% of the seniority list to go to some other airline
And anyone is fooling themself if they think anyone in the top 500 are going ANYWHERE, accept MAYBE flowing through. These guys are at max pay making 100K/ yr. and holding weekends off. Of the next 500, I'll bet less than 50% are thinking of moving on. They too are making close to six figures, and holding at least one weekend day off. I'm not trying to discourage you, but most of the guys willing to leave will be in the 900+ range. Unfortunately, many of them don't have the requisite PIC.
I've been at Eagle 7+ years and am happy with my choice. Mesaba and Air Wisconsin were my second and third choices, and the last few years would've been miserable at either (for me). Your situation is undoubtedly different. I can just now hold prop CA, although I've not taken it yet. Learn everything you can and explore all your options (what about Compass?) and cross your fingers! Welcome to the circus some call a career!
