Delta Threatens CrowdStrike With Lawsuit for Customer Damage

Delta CEO Ed Bastian announced that the airline is facing a $500 million revenue loss, along with other extra costs, due to the cancelation of thousands of flights. The company has threatened to file a lawsuit due to the damage.

Last July 19, several business operations were halted as more than eight million computers with Microsoft Windows were affected by a faulty software update from CrowdStrike. The global IT outage was addressed by the cybersecurity company after a few hours.

According to Bastian, Delta's operations are more dependent on Microsoft Windows compared to other airlines, causing more damage to its company. The CEO also claimed that CrowdStrike did not provide help aside from free consulting advice, which the latter refuted.

CrowdStrike Says Delta Contributes to Misleading Narrative Against Company

In a letter sent to Delta's lawyer David Boise, CrowdStrike stated that the airline's lawsuit threat "has contributed to a misleading narrative that CrowdStrike is responsible for Delta's IT decisions and response to the outage."

CrowdStrike also questioned why other airlines managed to recover from the outage quickly, leaving Delta in a slow recovery. The company's CEO George Kurtz revealed that it has personally contacted Bastian to help but the airline did not respond.

The U.S. Department of Transportation has initiated a probe into Delta's slow recovery compared to the other airlines after the incident. The agency is also looking at customer complaints against the company's service.
