Transportation Secretary Sean Duffy said the US Federal Aviation Administration will release a plan today to reduce flights at Newark airport after systems outages and a staffing crunch pushed the agency to slow traffic over the last several weeks.

The Federal Aviation Administration said on Tuesday it would require flight cuts at Newark, one of the main airports serving New York City, after it met with U.S. airlines to address congestion issues following a series of major disruptions.

The regulator said the reductions were needed to help reduce delays stemming from staffing challenges, technology outages and construction.
