U.S. regulators are investigating how Delta Air Lines is treating passengers affected by canceled and delayed flights as the airline struggles to recover from a global technology outage.
Transportation Secretary Pete Buttigieg announced the Delta investigation on the X social media platform Tuesday "to ensure the airline is following the law and taking care of its passengers during continued widespread disruptions."
"All airline passengers have the right to be treated fairly, and I will make sure that right is upheld," Buttigieg said.
Delta canceled more than 400 flights Tuesday by midmorning, accounting for about two-thirds of all cancellations in the United States, according to FlightAware.
The outage began Thursday night into Friday morning, after a faulty software upgrade from cybersecurity company CrowdStrike to more than 8 million Microsoft computers around the world.
