It's quite funny that in the midst of the crowdstrike thing yesterday, someone tweeted - afaict as a shitpost - that Southwest Airlines were unaffected due to running windows 3.1. Then digitaltrends published that claim using the tweet as a source, and are now being quoted themselves as a source.
AFAICT, it's entirely bollocks. Same with the claim they still run Windows 95, that's from the same lazy digitaltrends article, misquoting another misquote from 2 years ago.
The original publisher of the bullshit claim seems to be https://www.digitaltrends.com/computing/southwest-cloudstrike-windows-3-1/ , which was then syndicated to olds everywhere via yahoo.
It quotes a tweet that has no sources and seems to be clearly a joke. It also claims that Southwest's systems are "reportedly" built on windows 3.1 and 95, and links to https://www.forbes.com/sites/hershshefrin/2022/12/31/can-southwest-airlines-fix-its-systemic-weaknesses-in-the-new-year/ as a source, which doesn't say that.
@danderson I saw earlier jokes about Southwest using C64s that seemed even less likely.
If anything I’d more likely believe that instead of moving off the old systems airlines developed for computerized ticketing they just loaded the system up with related apps and kept elderly mainframe code running in some fashion.
Or, more likely, they use a different security package.
