A widespread Microsoft outage, triggered by a software update from CrowdStrike, has paralyzed air travel across the globe, affecting major airlines and leaving passengers stranded. As of Friday morning, more than 3,000 flights within, into, or out of the U.S. were canceled, with over 11,400 flights delayed, according to FlightAware.
The outage disrupted airlines’ back-end systems used for crucial flight operations, including the transmission of vital data like weight and balance information necessary for departures. Passengers at airports worldwide faced long lines at ticket counters and encountered the notorious ‘blue screens of death’ on display monitors.
“This is a PR nightmare for CrowdStrike and Microsoft,” commented Wedbush analyst Dan Ives, reflecting on the widespread impact on travelers globally. European airlines such as Lufthansa, KLM, and SAS reported similar issues, while Switzerland’s Zurich Airport temporarily halted incoming flights.
In Australia, Jetstar canceled all flights from Brisbane for the day, compounding disruptions. Across various continents, travelers shared stories of significant financial losses and logistical challenges due to flight cancellations and delays.
Delta Air Lines, United Airlines, and American Airlines were among the worst affected, collectively canceling thousands of flights throughout the day. Delta resumed some operations after an initial pause, while United and American Airlines advised passengers to expect ongoing disruptions.
The airlines have issued travel waivers to facilitate changes in travel plans amid the ongoing crisis. As efforts continue to resolve the IT outage, the impact on global air travel underscores vulnerabilities in digital infrastructure and reliance on technology for aviation operations.
