Delta Air Lines canceled more than 600 flights on Monday, as the U.S. air carrier continued to struggle to restore operations after last week’s global cyber outage.
About 16% of Delta’s flights had been canceled as of 7:00 a.m. EST, according to data from FlightAware.
The issue has stranded thousands of Delta travelers across the United States.
The Atlanta-based airline is battling operational issues after the outage hit its crew tracking system. Delta’s total number of canceled flights since Friday has exceeded 5,000.

A software update by global cybersecurity firm CrowdStrike triggered system problems for Microsoft customers, including many airlines, on Friday.
Although other U.S. airlines have largely recovered, Delta has struggled to return to normal. American Airlines had called off 1% of its flights on Monday, while United Airlines canceled less than 1%.
Delta CEO Ed Bastian said over the weekend that the CrowdStrike issue affected its Microsoft Windows systems, snarling a critical application.
“One of our crew tracking-related tools was affected and unable to effectively process the unprecedented number of changes triggered by the system shutdown,” Bastian told customers in an email.
CrowdStrike said a significant number of the 8.5 million affected Microsoft devices were back online.
