I would love to know what the cost of today's outage in terms of overtime, gate fees, fuel, additional crew, &c.
Delta's cost ~$150MM [1]. That's something on the order of a thousand mid- to senior- level programmers for a year in my area. Even if you allocate a quarter of that cost to computer costs (which I'm betting is a fairly large over estimate), that still leaves a sizable team.

TUI interfaces can be really, really efficient in terms of navigation and getting around. I rarely see GUI apps that function anywhere near as smoothly or keyboard only.

TUIs have a steeper learner curve, but I agree that once someone masters the hotkeys for that particular interface, they're much quicker. In addition, depending how old the computer is running the TUI, the staff may not be able to use the computer to browse anything else. ;)

I shudder to think of a scheduling program as complex as an airline's ticketing system being run on a bit of software written by a thousand programmers in only one year.
Okay, I admit that I have absolutely no idea what software like that costs to build, but surely they could have rebuilt their entire software stack for that, couldn't they?
No. Software at that scale is humungously expensive.
I worked on quoting an insurance policy core (just the core mind you, not the extras), and for a medium-sized insurance company it would reach that amount of money.
I suspect a complete rewrite would go into the billions.
The company I worked for ended up not doing it (and regretting it).
It ends up not being that many people, but extremely high paid consultants (200 to 400 dollars an hour), and extremely high licensing costs. Some projects can go on for years, should be 1 to 2 years.
It's extremely profitable and very well paid, one such company, Guidewire, is one of the top 10 best paying employers in the U.S.
