I agree with your sentiment about Delta people. In 17 years, probably only 5 rotations I would consider not wanting to do again due to personality conflict. Also, I've never flown with a Delta pilot I would hesitate to put my family onboard with (in regards to safety).
I've always been proud that I work with people that are willing to spend 8-16 hours together in a cockpit and then be willing to go out for dinner and drinks for another 3 or 4 (sometimes more).
Nice thing about working for Delta: I may have never met the next captain I'm going to fly with, but I pretty much know how it's going to go. And I'm looking forward to it.
