Carl;
DAL has done conceptual openers in the past. This is where the history is coming from. Go ask your reps if they are on board with this and why. Then come back and tell us why conceptual openers that do not nail down everything to a T are better for a pilot group.
What this means is the MEC gave laser specific direction to the Negotiation committee on bullet point items in each section and then they present a conceptual opener to the company as to not give away the store.
I will wait and see what the opener is and then read it and the updates from the reps from around the system. I bet that you will get a good idea where we are going if you cannot for some reason glean it out of the opener.
