More flight cancellations are expected as airlines gradually recover from global tech outage

Additional flight cancellations are expected through this weekend as airlines gradually recover from a global tech outage that has left thousands of passengers stranded at airports. More than 5,400 flights into, out of, or within the US were canceled Friday and Saturday and more than 21,300 flights were delayed. A third day of chaos at airports could be in store with more than 600 flights already canceled Sunday morning. The issue extended beyond airports, with businesses, government agencies, health and emergency services, banks, schools, and universities around the world grinding to a halt or seeing services disrupted due to a flawed software update for Microsoft Windows operating systems issued by the cybersecurity firm CrowdStrike, experts said. Major airlines have said services are being restored, but that there could be more delays and disruptions.
