Newark Airport has faced a number of air traffic control equipment outages in recent weeks.

Nearly 80 flights have been cancelled and more than 40 delayed at Newark Liberty International Airport after yet another an equipment outage brought more chaos to the NYC-area hub.

Passengers traveling in and out of Newark at the end of the week shouldn't expect smooth sailing. Here's the latest at the New Jersey airport.

Transportation Secretary Sean Duffy tells "CBS Mornings" it will take months to restore normal operations at Newark Liberty International Airport.

Caught in the middle of the issues at Newark is United Airlines, which is the most active airline at the New Jersey airport. While the problems lie with the FAA system, the airline is where people often aim their frustrations over cancellations and delays.

Several times over the last year, Newark controllers lost radar or radio service, leaving them unable to talk with planes they were tracking.

The air traffic controllers directing planes into the Newark, New Jersey, airport lost their radar Friday morning for the second time in two weeks.

The claims, which the Federal Aviation Administration hasn’t confirmed, emerged a week after Newark airspace controllers lost all communication for as long as 90 seconds.

Similar to last summer, there is currently a nationwide shortage of air traffic controllers, which will “take time” to replenish, according to Transportation Secretary Sean Duffy.

United Airlines Holdings Inc. expects flight reductions at Newark airport to linger through summer and into fall as the crucial travel hub struggles to recover from air traffic control glitches that have already disrupted hundreds of flights.
