Earlier last week, United Airlines experienced a major technology failure that led to a nationwide grounding of all it’s mainline flights. The issue stemmed from a breakdown of one of their internal platforms that’s used for flight planning, crew scheduling, and weight calculations. Though the system was eventually restored, the disruption impacted airports across the country, leading to over a thousand delays and dozens of cancellations. While United confirmed it was not caused by a cyberattack, the incident shows just how must operations rely on the seamless collaboration of technology.
