Of all the articles to post proving SWA pilots deserve a raise, this might be the worst.

"When he took over as CEO, Jordan was moving up from an executive vice president position, and the pay hike was part of his promotion. -- Jordan’s total compensation package last year came to $5.3 million, up from $3 million in 2021. His predecessor as CEO, Gary Kelly, received $5.1 million in 2022, serving as CEO in January and executive chairman the rest of the year. That’s down from the $5.8 million Kelly received in 2021 and $9.8 million he received in 2020."

Any FO that upgrades at SWA has gotten a 50% raise.
The answer from SWA management to you saying contract C2020 items aren't too expensive could literally quote this same article, say that the CEO position of SWA took a 45% pay cut since 2020, and you should do the same.

Yes, you should get a hefty raise. But read the article before you post.
