Where did you get your information? I have experience in the industry and scheduling logistics is clearly not how you describe it. The issue is that to optimize for profit you sacrifice the ability to maintain service through catastrophic events and can end up in a bit of a dominoes situation.
Or are you asking why I think they're making it up as they go along? That is my conclusion, to be sure. It's one thing for dominoes to fall, but if you are in a situation where the dominoes are falling and you are not able to predict which dominoes will fall next and respond accordingly, you are making things up as you go along. I'd have expected that almost any decision they could even hypothetically make would run through a system that checked it for violations of constraints, which would have told them way ahead of time that they needed a fresh crew, and they'd have had the entire flight of the replacement plane to get one in (IIRC it flew Miami->Boston just to get us the plane).
As for your conclusion, it's just not accurate. Systems _are_ used for scheduling and allocation of equipment and crew resources. You just have to realize that getting you, as an individual, to your destination on time on any given day isn't the number one priority of the company. There are a lot more concerns they are considering. If the airline industry is really as dysfunctional as you think, with such shortcomings in areas as important as equipment and crew scheduling and allocation, you should drop whatever you're doing and start an airline. You'll soon be filthy rich and do the world a great service.
Also your generalizations fly directly in the face of the information emerging from this Southwest fiasco, which indicates they don’t have systems in place to even track where their crews are (just where they are scheduled to be), so the shortcomings seem to be quite real.
Sounds like an argument for nationalization.
Airlines run on very thin margins, so need to optimize heavily.
We just need to accept that we can either get "affordable" tickets with occasional meltdowns or we go back to 30 years ago and pay double price for tickets but have more resilience.
The market as a whole has already resoundingly chosen the former.
Safely flying humans in metal structures is just really expensive and the current ticket prices pretty much reflect the real cost (and even ignore the climate externalities)
Who cares? The point of nationalization is costs don't matter, we just see it as a cost we bear because transportation is important for civilization. The primary mode (for better or worse) in the US is public (roads) and that "cost" is not covered by anyone.
No, it sounds like an argument to never fly SWA again.
