Slotted seniority has real problems. How do you account for the next merger? Do you slot all the way through the seniority list? That creates a huge blow for the junior NWA pilots. There are other options other then a dynamic list. A dynamic list means 20 more years of arbitration rulings like the current NW. We don't need that. I would split the difference between a ratio and DOH and even give NWA fences on the 747's with no fences on 777 ordered after the DCC.
