According to reports, Newark Liberty International Airport is facing widespread disruptions this week, with hundreds of flight delays and cancellations triggered by a combination of air traffic controller shortages, aging equipment, and runway construction.

The Federal Aviation Administration (FAA) has confirmed that more than 20% of the air traffic controllers responsible for managing Newark’s busy airspace are on extended medical leave. The absences stem from reported trauma linked to recent system failures, including a 90-second blackout last week that left incoming aircraft temporarily invisible to radar and without communication.

The incident, caused by a burned-out copper wire, is raising concerns about the condition of the airport’s infrastructure. In addition to equipment malfunctions, one of Newark’s main runways is closed for construction until at least mid-June, reducing the airport’s flight capacity.

United Airlines, the largest carrier at Newark, has preemptively canceled 35 daily flights—about 10% of its schedule—to help ease congestion. In a statement, United CEO Scott Kirby said the airport “simply cannot handle its current volume of traffic” under present conditions.

According to FAA data, the average delay for arriving flights at Newark has exceeded three hours, while departing flights have also faced extensive wait times.

In response to the escalating crisis, Transportation Secretary Sean Duffy announced new efforts to recruit and retain air traffic controllers, including incentive packages and modernization of control systems. However, implementation of these measures may take months or longer.

Senate Majority Leader Chuck Schumer has called for a formal investigation into the FAA’s handling of staffing and infrastructure issues, citing long-standing concerns over the agency’s preparedness and oversight.

Passengers planning to travel through Newark in the coming weeks are encouraged to check their flight status regularly, consider alternate airports such as JFK, LaGuardia, or Westchester, and take advantage of flexible rebooking options. United is waiving change fees for affected passengers traveling between May 6 and May 17.
