Arrivals at New Jersey's Newark Liberty International Airport are being limited to as few as 20 planes per hour, per the FAA and New York City Emergency Management. The average delay for arriving flights was over 3 and a half hours. The traffic management program at Newark will run into early Monday morning, per the FAA's most recent advisory. Transportation Secretary Sean Duffy tweeted to warn Newark travelers to "expect significant delays. We HAVE to reduce flight volumes to MAINTAIN SAFETY." Duffy also blamed Democrats, including New York's Sen. Chuck Schumer and Rep. Hakeem Jeffries, for the shutdown, saying that airspace would return to normal once a deal is made. Staffing-related ground stops and delay programs were also issued for Nashville and San Francisco, though they were canceled by early afternoon as the system struggled to adapt.
