American Airlines, United and Delta are grounding flights citing communications issues, according to the Federal Aviation Administration’s advisory page — as mass IT outages affect businesses across the world.
The groundings come hours after Microsoft said it had resolved a cloud services outage that had forced a grounding of Frontier and Sun Country flights, though it is unclear if the groundings of departing flights from major air carriers are related.
Cybersecurity firm CrowdStrike, in a recorded phone message, said it was aware of reports of Microsoft Windows errors related to its technology.

American Airlines said it was “aware of a technical issue with CrowdStrike that is impacting multiple carriers. American is working with CrowdStrike to resolve the issue as quickly as possible and apologize to our customers for the inconvenience.”
Businesses around the world, including The Washington Post, reported experiencing issues with Microsoft Windows overnight Thursday into Friday, with users reporting “blue screen of death” (BSOD) errors. At least some resumed functioning shortly afterward.
