the only thing both sides agreed too was to modify the timeline and the number of arbitrators. Something allowed by ALPA merger policy. As far as how the arbitrators rule, I qoute from the SLI process agreement:

"The issue for resolution before the Arbitrators will be the fair and equitable integration of the pre-merger Delta and Northwest seniority lists consistent with ALPA Merger and Fragmentation Policy ("ALPA Merger Policy"). In making this determination, the Arbitrators will be bound by the pre-arbitration statement of resolved issues presented by the Representatives and will determine the remaining open issues with respect to an integrated seniority list."
