Domestic Flights Resume In NJ, PA After FAA Outage

Domestic flights out of airports in New Jersey and Pennsylvania were delayed Wednesday morning amid a nationwide Federal Aviation Administration outage.

The FAA lifted the ground stop, and flights at the Newark Liberty International Airport resumed as of 9 a.m., the FAA announced. But resuming normal operations around the nation will be gradual, and thousands of U.S. flights remain delayed or canceled as of 9:30 a.m.

The FAA said Wednesday morning it was working on restoring its Notice to Air Missions System. The agency said that it would provide frequent updates as it made progress.

"The FAA has ordered airlines to pause all domestic departures until 9 a.m. Eastern Time to allow the agency to validate the integrity of flight and safety information," the FAA said.

According to flight-tracking website FlightAware, Philadelphia International Airport is experiencing arrival delays of about 1 hour, 25 minutes as of 9:40 a.m., with arrival delays averaging 1 hour, 5 minutes. Those delays are increasing, the tracking website said.

Delays at Newark Airport are estimated at about 90 minutes, with arrival delays increasing, FlightAware reports.

"The FAA is still working to fully restore the Notice to Air Missions system following an outage," the agency said in a tweet. "While some functions are beginning to come back online, National Airspace System operations remain limited."
