CrowdStrike outage is still causing hundreds of flight cancellations daily

Three days after a faulty update in cybersecurity company CrowdStrike's software caused a global IT outage, thousands of flights are still being cancelled or delayed.

The CrowdStrike outage may feel like distant history as so many things happened in the last couple of days, including President Biden announcing he's dropping out of the 2024 presidential race.

But the issue, which impacted an estimated 8.5 million Windows computers, is still causing disruptions in numerous sectors, with airlines being among the most impacted.

According to Reuters, Delta Air Lines had to cancel 1,250 flights on Sunday, and an additional 305 flights on Monday, with the total number of canceled flights being at more than 5,000.

"As we continue operational recovery, we apologize for the disruptions many customers are experiencing. Canceling a flight is always a last resort & not taken lightly," Delta wrote in a post on X. "We’re notifying customers about delays & cancellations in their itinerary via the Fly Delta app & text message & offering re-booking options that can be managed online."

United Airlines is another airline who was hit hard by the CrowdStrike outage, but it recovered better, having cancelled 266 flights on Sunday, Reuters reported.
