A higher FlightAware count for Friday's cancellations has emerged. Fox Weather, citing FlightAware, reports more than 9,100 flights cancelled and more than 24,500 delayed on Friday 13 November. That is above the earlier FlightAware figure of more than 8,860 reported by Euronews.
ABC News has headlined its live blog "More than 12,500 flights canceled Friday and Saturday". The headline does not name a source. The text beneath it still carries older figures of nearly 5,000 cancellations for Friday and nearly 800 for Saturday.
Neither outlet says when its count was taken. The figures come from different sources and cover different periods, so they cannot be compared directly.
Fox Weather also reports that 387 commercial flights took off after the ground stop was lifted. It gives the lift time as 8pm, but the FAA has given it as 8.15pm ET. Fox Weather also dates the start of the stop to 4pm ET, while the FAA advisory gave 3.54pm ET.
Fox Weather describes the stop as the longest nationwide US airspace ground stop since 9/11, which is consistent with AP's reporting.
The cancellation totals have not been independently checked.
