FAA halted every U.S. departure for more than four hours after a telecom failure hit all 22 high-altitude control centers
More than 6,300 flights were canceled and 9,500 delayed by the time it lifted, per FlightAware; the U.S. system handles about 45,000 flights on a typical day.
Canceled flight, or a domestic arrival 3+ hours late: you can decline the trip and get a cash refund, even on a nonrefundable ticket, per DOT rules.
ContextThe last nationwide ground stop came in January 2023, when the Notice to Air Missions system failed. That system sends pilots safety alerts before they fly. This time the failure hit all 22 high-altitude control centers at once. Former NTSB (National Transportation Safety Board, which investigates crashes) chair Robert Sumwalt called it "absolutely unprecedented." When the stop began, about 3,100 aircraft were in the air bound for U.S. airports, per Flightradar24 data cited by CBS News. The Guardian put the figure at more than 1,000. The flights canceled and delayed on Friday, Nov. 13, add up to about a third of the roughly 45,000 the U.S. system handles on a typical day.
