@maxkennerly @kornbluh I used to work in aviation. Even in the best of times, airlines are barely profitable - see chart linked. https://archive.ph/KqZ5R
And they lost a lot of money during the pandemic. So if they put off the large capital and operational expense of moving to a new scheduling system, I understand why.
Of course the outcome of that gamble was not fun for anyone involved. But the idea that the airlines are rolling in money, or that they over-reward their shareholders, does not seem to be in keeping with the facts.
More to the point, I'm not sure the stock market is going to reward Southwest for what happened. The reputational hit alone is going to be significant. This will damage both the airline and its shareholders.
As for regulation, the idea that aviation - an industry dominated by regulation - needs more, is at best problematic. You only need to see how sternly the Dept of Transportation reacted to this to know how tightly controlled this space is.
More regulation would likely lead to even more unintended consequences, most of which would impact consumers.
