Too bad the the same arbitrators are not involved or I might by some of your logic. In fact one of the 3 involved ruled on the final arbitration of the NWA Red Book/Green book just recently, and the gist was that (framed in the context of the original Roberts award), that the pre-merger NWA group did not have a continuing right to meter awards based on equipment (Wide Body).
I find it fascinating that many here seem to put more weight on what equipment one is awarded while completely ignoring the demographics of a base/position that allows it to go so far out of normal seniority.
A better litmus test might be what seniority does it take to hold be a ATL 767 intl line holder?
I think it's great that a new hire a DAL can hold a 767 intl' out of JFK, but it's moot, and that somehow that should be protected regardless of the demographics of the pilot group and alignment of bases and aircraft (that is going to change), as if your seniority only matters if it allows for upward movement and not downward.
Thankfully there will be 3 very experienced arbitrators, and I'm confident we will get something much closer to a middle of the road solution than what was seen either at NWA with Roberts, or Nicilou(?).
I also heard that there is nothing to prevent a negotiated SLI to be agreed upon even after the ruling.
