Tom’s Hardware reports while other airlines struggled with operational disruptions due to their reliance on more modern computing systems, Southwest’s continued use of Windows 3.1 spared it from similar issues. The airline’s outdated technology, often the subject of ridicule, ironically served as a buffer against the widespread system failures affecting others.

Despite Southwest’s systems running just fine, other airports faced issues so that indirectly impacted the airline’s operations, just not as much.

Southwest isn’t entirely reliant on Windows 3.1 (that would be ridiculous) as the airline also reportedly uses Windows 95 for staff scheduling, another OS that never received the problematic CrowdStrike update.

Although running outdated software saved the day this time- or at least put the airline in a better position than its contemporaries – Southwest will eventually need to update its operating systems, as newer computers will struggle to run them.

One X user suggested that the company switch to Windows XP because, while it also no longer receives updates, it’s newer (relatively speaking) and can run Windows 3.1 software in compatibility mode.
