If you guys ever walked a mile in a Comair pilot's shoes, you'd understand his frustration. We all experienced it, even those of us that had nothing to do with the shenanigans of the early part of the last decade.
Some of the shunning of the Comair guys by the Delta guys was real, some was just perceived but regardless, there was bad blood on both sides. Lots of people on both sides couldn't let go of the past and move forward. Unfortunately, it was the junior Comair guys that had nothing to do with any of it that paid the price for the mistakes and miscommunication and other nonsense of the early 2000s.
His frustration is understandable from my point of view.
