On Monday, September 21, 2026, more than 1,300 flights scheduled at Newark Liberty International Airport, Philadelphia International Airport, and nearby New York City airports faced cancellations, delays, or diversions after an accidental cut to a Verizon fiber optic cable in New Jersey.
Construction workers engaged in a rail project between New Brunswick and North Brunswick severed a Verizon cable approximately 10 feet from recorded utility markings, disrupting a backup fiber optic data feed vital for air traffic control. FAA Administrator Bryan Bedford explained that an initial failure in the primary circuit forced switching to the backup feed, only to discover
it too was broken.
Operations Impact at Major East Coast Airports
The Federal Aviation Administration immediately paused arrivals at Newark Liberty International Airport and Philadelphia International Airport to ensure safety. By 6 p.m., FlightAware reported over 600 canceled flights and nearly 100 delays at Newark, representing more than half the day’s scheduled takeoffs and landings. Philadelphia experienced over 200 cancellations and 400 delays. Additional FAA halts extended to LaGuardia Airport and John F. Kennedy International Airport in New York City, with flights resuming Monday evening but carrying residual delays.
At least 100 flights incoming to Newark were redirected to alternative airports such as Detroit Metropolitan Wayne County
and Washington Dulles International airports. Several international flights—originating from countries including Iceland, Egypt, Greece, Spain, France, Germany, and Sweden—were among those diverted.
Passengers were impacted with extended travel times and long waits, including periods on diverted flights. United Airlines and American Airlines responded by waiving flight change fees and allowing use of alternate airports. United also offered additional pay to staff volunteering for extra trips at Newark.
Agency and Company Responses
Verizon issued a statement confirming that construction contractors working near the cable had dug up and cut their fiber optic line. The company said its facilities were fully operational before the incident and
denied responsibility for the cut. Verizon technicians were promptly dispatched to repair the damage and restore service.
NJ Transit acknowledged that construction crews “accidentally severed a fiber-optic cable while working at the site” and declared an ongoing investigation to clarify the accuracy of the utility markings and repair responsibilities.
FAA Administrator Bryan Bedford detailed how “when it went to flip into the backup, we discovered the backup fiber had a break,” underscoring the failover mechanism’s failure. Transportation Secretary Sean Duffy reported on social media that flights resumed after repairs were completed Monday evening, emphasizing the urgency for infrastructure modernization funding
to prevent future incidents.
Context of Aging Air Traffic Control Infrastructure
The incident exposed vulnerabilities within the U.S. air traffic control system, reliant on aging fiber optic and radar infrastructure. Despite a multibillion-dollar overhaul plan announced by the Trump administration in 2025 aimed at modernization, the disruption revealed ongoing challenges. Transportation Secretary Duffy called for additional funding to upgrade equipment and avoid similar operational disruptions.
Ongoing Investigations and Recovery Efforts
FAA halted flights at affected airports as a precaution following the cable cut. Full restoration occurred later the same day, with flights resuming at Newark, Philadelphia, and New York area airports by Monday evening, though some delays persisted.
NJ Transit remains on
site investigating utility marking accuracy and repair obligations. Verizon is actively working to complete repairs to the damaged fiber optic cable. Airlines continue to manage staffing and passenger accommodations in response to the significant operational impact on the busiest international hubs at Newark and Philadelphia.
