FlightAware counted more than 8,860 cancellations of flights to or from the US on Friday 13 November, Euronews reports in a story carried by Yahoo Australia and IndexBox.
For Saturday 14 November, Euronews cites FlightAware for around 2,650 cancellations so far. CNBC, also citing FlightAware, reports more than 3,400 cancellations and more than 6,200 delays as of early Saturday. Neither report says exactly when its count was taken.
The two Saturday figures appear to come from the same tracker at different times. They should not be set against AP's figure of more than 2,000 cancellations on Saturday, which is a separate count. Nor can they be compared with Flightradar24's total of nearly 10,000, which covers Friday and Saturday together.
The FAA said in a post on X on Saturday that it had lifted the ground stop and some departures were resuming, CNBC reports.
The FlightAware figures have not been independently checked.
