SWAPA does have one that they have published but I don't have it with me. Maybe if you Google "SWAPA contract comparison"? Maybe Reddit has something?

I have a copy of the United Airlines contract comparison that they published in Q1 2017. What is very interesting about that is that they have charts in the back comparing 30-year career compensation between the various airlines and modeling different career progressions. Here are the caveats that they list: "Charts depict the retirement growth of a pilot starting their employment January 1st 2016. All charts are based solely on company contributions. No pilot deferred compensation has been added. At properties that have a 401 (k) match the full match value is included, but the pilot contribution has not been included for consistency. Charts assume no profit sharing. Contributions are based on the pilot crediting 1,000 hours per year. An annualized growth rate of 8% was used. Only current known pay rate increases have been included. Compensation over the IRS limit of $265,000 is not included."

At SWA, assuming a 10-year upgrade, total career compensation is $3.759M.

At UA, assuming 5 yrs as a 737 FO, 5 yrs as a 777 FO, 5 yrs as a 737 CA, then the remainder as a 777 CA, total career compensation is $4.709M. That's just under $1M in career compensation difference. Realize that upgrade time at UAL is reportedly significantly better than that chart assumes and at SWA, it's right at 10 years and maybe a little more than that.
