Yes, it is almost certain that the arbitrators aren't going to use the seniority_list program in this integration. But it can still be used now to understand and compare the proposals.

The seniority_list program was developed out of frustration with the current process. It is a comprehensive tool which provides quantifiable insight into how integrated seniority list proposals would actually affect the careers of pilots, both short- and long-term.

The east committee did not use the seniority_list program at all and it is not affiliated with any law firm.

The hope is that someday pilots will realize that the current process is largely based on arguments which have nothing to do with flying airplanes and everything to do with lawyers, inevitably leading to winners and losers and fractionalization of the combined group.

Before making a judgment about "python crap", please take a look at the paper which was published through Cornell University last year and the documentation website for the program. While it is too late to help with the Alaska-Virgin merger, it certainly can help with future integrations if there is a will to do better and avoid repeating the mistakes of the past.

Please note that the program has been updated and improved since the paper was published.
