Many flights have been delayed at the busy hub because of radar outages, shortages of air traffic controllers and construction on a runway.

Transportation Secretary Sean Duffy says a new software update prevented a third radar outage over the last two weeks at New Jersey's busy Newark airport when a telecommunications line failed again over the weekend.

Staff shortages and equipment failures at Newark Liberty International Airport have raised safety concerns in recent weeks.

The Federal Aviation Administration is working on a short-term fix to the problems at the Newark airport that includes technical repairs and cutting flights to keep traffic manageable while dealing with a shortage of controllers.

The Federal Aviation Administration is considering temporary flight reductions in and out of Newark Liberty International Airport, and it's launching a safety task force.

Transportation Secretary Sean Duffy released a four-point plan to address the failing infrastructure at Newark Liberty Airport.

The shortage on Monday forced the F.A.A. to delay flights to the busy airport for up to nearly seven hours, the latest problem to plague the airport.
