Washington : The US Federal Aviation Administration (FAA) lifted a nationwide suspension of departing flights after a communications system failure at air traffic control centres disrupted operations for more than four hours.
FlightRadar24 reported that more than 4,700 flights were cancelled and 10,000 delayed on Friday, with another 700 cancellations on Saturday. Airlines could take several days to restore normal schedules.
The US Department of Homeland Security said there was no indication of a cyberattack or a link to the Microsoft systems outage. S Transportation Secretary Sean Duffy attributed the disruption to outdated equipment.
