My advice, don't even think about 9E
I jumped ship January 2015 from Endeavor. It is one of the last places I would recommend anyone going to right now. Forget about that bonus money(do you want to make a regional your career?). Other regionals have actual growth, better contracts, and upgrade opportunity which is what really matters. Check out the CQFO program at TSA or look at Compass. But who knows what Delta's plan for 9e is. They can be ruthless and will do whatever they can to get their bonus checks. If you go to 9E expect a so so contract, 11 days off, and flying with some seriously low moral pilots. Oh and hope you like NYC or one of their other fine bases.
