Officials blamed old equipment for the outage and said nearly 6,000 flights were canceled before airspace reopened, according to FlightAware.

  • This alert marked the second such stoppage in U.S. airspace since 9/11; FlightAware data shows nearly 6,000 flights were canceled, while Hartsfield-Jackson Atlanta International Airport logged 628 delays and 22 cancellations.
  • At 8:15 tonight Eastern Time, Transportation Secretary Sean Duffy announced at a White House briefing that airspace "opened up," though officials warned clearing travel chaos would take time.
  • Following the breakdown, Duffy and the White House asked Congress for US$30 billion to modernize the Air Traffic Control System, while insisting it remained safe for Americans to fly.
