Cancellations of US flights scheduled for Sunday 15 November had reached 910 by 10.33pm ET on Saturday, ABC News reports, citing FlightAware. The number was still rising at that point. It was more than 800 at 9pm ET.
JetBlue had cancelled a quarter of its Sunday flights and American had cancelled 293, Yahoo News reported early on Sunday.
For Saturday itself, Reuters puts cancellations at more than 6,400 and delays at more than 8,000 as of 9.35pm ET, using FlightAware data. ABC News says nearly 9,200 flights were cancelled on Friday and that the total across Friday and Saturday is above 14,000. The two daily figures add up to more than 15,000, so ABC's total holds up.
The FAA Administrator, Bryan Bedford, said airlines expected "full schedule integrity" by the close of business on Sunday, ABC News reports. That matches his earlier comment that normal schedules were unlikely to return until late Sunday.
American Airlines said on Saturday night:
"American's recovery from yesterday's FAA nationwide ground stop continues to move forward"
These counts were taken on Saturday night, US time. Sunday's figures will have changed since then.
