Yes, must-work days would go away with a real PBS. I'm not sure why Nate is caught up on this stacking issue, I guess there's nothing else to complain about. It's not like the company has offered us industry-standard everything (or basically anything). If stacking/unstacking was all that was left, it might be a different story. However, we're still a Grand Canyon apart and there are a dozen things the pilots DO want that the company is refusing to give, so stacking right now is a moot point.
Nate, if you are so concerned why don't you tell everyone here how delta does it? You seem to be an expert. Please enlighten us. I would much rather AR spend his time trying to get my LTD and min day than worrying about your stacking question.
Also, our current CBA doesn't allow unstacking, I'm curious as to why you would want to give that up to the company in this environment.
