U.S. travelers coped with late flights and cancellations on Sunday, one day after a now-resolved computer failure at a regional air-traffic control center disrupted operations from New York to Florida.
At least 2,250 U.S. flights were late on Sunday and more than 150 were canceled, according to FlightAware.com data. The airports with the most affected departures included those in Philadelphia and Washington, the flight-tracking website showed.
Travelers in some East Coast airports on Saturday were delayed more than three hours before the Federal Aviation Administration fixed the air-traffic control computer breakdown and ended flight restrictions late in the afternoon.
On Saturday, some 3,800 flights within, into or out of the U.S. were delayed and 650 were canceled, according to the website. A statement from the Federal Aviation Administration said 492 delays and 476 cancellations were attributable to the malfunction in a five-month-old system installed to help upgrade the agency’s operations in Leesburg, Virginia.
“FAA air traffic has operated normally today,” Laura Brown, a spokeswoman for the agency, said Sunday in a subsequent e-mailed statement. “The FAA is continuing to work with airlines that may still be repositioning airplanes and crew members.”
The FAA is focusing on a recent software upgrade at Leesburg as the culprit that triggered the shutdown, Brown said in the statement. The software for the system tracking high-altitude flights was returned to an earlier version and the technology appears to be functioning fine, the agency said.
(An earlier version of this story was corrected to limit the flight figures to those into, out of, or within the U.S.)
