Delta Air Lines Inc (NYSE:DAL) has engaged a law firm and will pursue compensation from Microsoft Corp (NASDAQ:MSFT) and CrowdStrike Holdings Inc (NASDAQ:CRWD) for the global IT outage earlier this month which disrupted flights, according to a report from CNBC.
The Atlanta-based airline has cancelled more than 6,000 flights, including 2,200 flights on July 19, due to the outage.
It has reportedly engaged David Boies, the chairman of Boies Schiller Flexner, to pursue legal action against Microsoft and Crowdstrike. No suit has been filed yet, CNBC said.
The outage cost Delta an estimated $350 million to $500 million, the publication said.
Delta has been the slowest of the US airlines to recover from the outage.
The US Transportation Department last week said it would be kicking off an investigation into the airline over the flight disruptions.
Delta, Microsoft and Boies Schiller Flexner did not immediately respond to media requests for comment.
"We are aware of the reporting but have no knowledge of a lawsuit and have no further comment," a CrowdStrike spokesperson said in a statement.
Shares of CrowdStrike fell on the news, down 8.4% at $237, while Delta shares added 1.5% at $43.65 in early trade on Tuesday.
