Southwest Airlines, the fourth largest airline in the United States, was hardly affected by the CrowdStrike — problem due to the use of Windows 3.1. The chaos occurred only on airlines that used current Windows.
However, the global CrowdStrike outage may provide arguments for Southwest not to update their systems. If a system doesn’t get updates, they won’t break it: «if it ain’t broke, don’t fix it». In X, one of the users suggested that the company switch to Windows XP: it is also no longer updated and can run Windows 3.1 programs in compatibility mode. Overall, the situation clearly demonstrates why some companies have been slow to update their hardware and software for decades.
