On September 21, 2026, construction workers in New Jersey accidentally severed a Verizon fiber-optic cable, disrupting a backup data feed essential to air traffic control across Newark Liberty International Airport, Philadelphia International Airport, John F. Kennedy International Airport, LaGuardia Airport, and Teterboro Airport. The Federal Aviation Administration (FAA) responded by halting flights bound for Newark and Philadelphia and delaying or canceling flights at several New York area airports.
Flight Cancellations, Delays, and Diversions Across Northeast Airports
By 6 p.m. on September 21, more than 600 flights in and out of Newark were canceled, accounting for over half of the day’s scheduled departures and arrivals. Newark also experienced nearly
100 delayed flights. At Philadelphia, over 200 flights were canceled and more than 400 delayed, compounding regional disruptions. Flights into JFK and LaGuardia were temporarily halted before resuming with continued delays. More than 100 inbound flights destined for Newark were diverted to airports including Detroit Metropolitan Wayne County and Washington Dulles International airports.
Officials and Corporate Responses to the Incident
FAA Administrator Bryan Bedford explained the outage began with a primary circuit failure at the Philadelphia TRACON facility. “When it went to flip into the backup, we discovered the backup fiber had a break,” Bedford said. NJ Transit reported that construction crews working on a rail project
between New Brunswick and North Brunswick, New Jersey, “accidentally severed a fiber-optic cable while working at the site,” despite operating about 10 feet from utility markings. Verizon stated, “Construction contractors working in the area dug up and cut our cable. Verizon’s facilities were fully functional up to that point. Verizon bears no responsibility for this incident.” Secretary of Transportation Sean Duffy confirmed that repairs were underway and that flights resumed later Monday evening.
Effects on Passengers and Airline Accommodation Measures
The fiber cut caused extensive travel disruptions, with hundreds of passengers facing flight cancellations, prolonged delays, and diversions across major Northeast airports. United Airlines waived change fees
for affected travelers and offered additional pay incentives to staff at Newark to manage operational challenges. American Airlines also waived change fees and permitted customers to use alternate airports in the region.
Aviation Infrastructure and Timing of Disruption
The incident occurred days before the United Nations General Assembly in New York City, an event increasing international traffic through area airports. The United States has faced longstanding challenges with aging air traffic control infrastructure. Last year, Congress approved $12.5 billion to upgrade the system, while Transportation Secretary Duffy has advocated for an additional $17.5 billion in funding to modernize the network.
Repair crews worked through the day
and evening, enabling the FAA to resume flight operations at affected airports by late Monday. The disruption collectively caused approximately 7,000 flight cancellations and delays as per FlightAware data cited by the Economic Times.
