More than 700 flights within, into or out of the US are already cancelled for Saturday 14 November, CNN reports, citing FlightAware.
This is the first figure for next-day cancellations. The 4,467 US cancellations that Fox News attributed to FlightAware earlier were described as occurring during the FAA ground stop.
CNN also reports that as of 7.45pm ET (00.45 UK), Delta Air Lines had cancelled 5% of its flights, United Airlines 4% and American Airlines 2%.
CNN does not make clear what period those percentages cover, including whether they refer to Saturday's schedule. They should not be read as a measure of Saturday's disruption.
None of the figures has been independently checked.
