I think my biggest beef is that they've basically taken the flying that used to be done by Mesaba. I never worked at Mesaba but I hear it was a fine company that paid fair wages and treated their employees pretty well. I actually feel bad for a lot of the ones I fly with at Pinnacle. They'll ask questions about things and be like "is this how it always is?" and I generally have to reply with "other airlines do it better than this wonderful company?" with as much sarcasm as possible.
So yes, the used to be Gulfstream argument is out. My rant is more that Delta continues to ruin careers of those working at regionals by constantly realigning their flying with the lowest bidder. It's just good business on paper, I realize that. Still doesn't change the fact that I don't like the business model.
