The context of the original answer I gave was relative health and smartly run to turn a profit. Those numbers are relevant because for the four largest carriers, ranging in US market share between 14.9% (United) and 17.6% (American), it shows the relative ability to turn a meaningful profit from that market share. BTW, Delta was 17.5%, and Southwest was 16.9%. (https://www.t4.ai/industry/us-airlin...enger%20miles.) So from a roughly equivalent market share amongst the four largest, DAL paid out more than double the profit sharing than the three other largest airlines, representing 49.4% of the US market, compared to Delta’s 17.5%.

The question of diluting those relative profits over the employee groups isn’t entirely irrelevant, but is more difficult to determine with digging quite a bit. Feel free to supply analysis and references to prove that Delta’s profit sharing wasn’t substantially better than the other other three big airlines. One of the things that the original PS agreement got right was the accounting methodology in order to keep the company from playing accounting games to avoid paying out to us. I have heard some discussion that other airlines wrangled more advantageous accounting rules for themselves to keep from giving too much to employees, but I don’t have any real insight into that angle. Back to the question of profit relative to employee groups in 2019, please refer to my previous post on the PS payouts, then do your own math with respect to employee groups. (not all comparisons are true apples to apples, but are sufficient to reinforce the point that our last prepandemic PS was an appropriate and persuasive measuring stick between airlines)
AAL 133,700 employees https://www.macrotrends.net/stocks/charts/AAL/american-airlines-group/number-of-employees
UAL 96,000 employees https://www.macrotrends.net/stocks/c...r-of-employees
DAL 91,000 employees https://www.macrotrends.net/stocks/c...r-of-employees
SWA 60,800 employees https://www.macrotrends.net/stocks/c...r-of-employees

Want to look at profit sharing paid just to pilots and the size of pilot groups? Be my guest and dig up those numbers. I doubt they paint a different picture than the company wide snapshot. If you want to nitpick beyond that level of granularity (because UAL has more WB aircraft, etc.), then I would suspect that short of a pronouncement from the Allmighty directly to you, that no answer will satisfy. I stand by my original post: basing is often the most persuasive factor in choosing between legacies, and then comparing PS in the last semi normal year leans heavily in Delta’s favor.
