Operations at Newark, one of the main airports serving New York City, have improved significantly after the federal government imposed flight cuts following a series of major disruptions, U.S. Transportation Secretary Sean Duffy said on Wednesday.

On May 20, the Federal Aviation Administration (FAA) announced an interim order reducing flights at Newark Liberty International Airport through the rest of the year.

At one point, the FAA had targeted 77 total arrivals and departures at Newark each hour, but at the start of construction on April 15 they requested airlines cut that down to 70 total during the day and 62 during specific hours in the late afternoons and evenings.
