Im at Compass as well, and no complaints. If you are thinking about coming here ONLY based on the flow-through, I would re-think it. Who knows what is going to happen with the flow though. We could luck out and keep it at Delta, we could lose it... your guess is as good as mine.
If you are thinking about coming to Compass to have a slightly better QOL, fly with great crews, fly a great plane then the decision becomes a littler easier. I dont know if I would make the decision based on the flow through.
