I also agree completely with Rickair...
However, I also want to add a few things.
First, don't despair over this!!! The majors are NOT the end all, be all. PLEASE don't think this way. If you have a quality corporate job now, be grateful. There is nothing wrong with staying corporate, and as Rickair said, you are much more likely to gain employment at other corporate flight dept's through networking etc.
I hate to be a buzz kill on the dream job, but there are far too many applicants available without these issues.
Whether or not you should leave to work GoJet (lucky guess).... That's on you. If your current company is stable and you feel the flight dept isn't going anywhere, I would stay. I can't see your track record allowing you to succeed in 121, but in 91 it's all networking.
Best of luck, but mostly keep in mind that being a Delta 777 CA isn't everything!!!!!!
