FAA Halts Inbound Flights Across East Coast Hubs After Control Facility Frequency Outage
Communications frequency issues at the Philadelphia TRACON facility caused 67 diversions and hundreds of delays across Newark, Philadelphia, and New York airports.
An equipment outage at an air traffic control facility disrupted flight operations across the eastern United States on Monday, forcing flight groundings and dozens of aircraft diversions, according to a report by CNBC Business (https://www.cnbc.com/2026/09/21/newark-philadelphia-nyc-flight-disruptions.html).
The Federal Aviation Administration halted inbound flights to Newark Liberty International Airport, Philadelphia International Airport, and New Jersey's Teterboro Airport due to frequency issues at the Philadelphia Terminal Radar Approach Control (TRACON) facility. The Philadelphia TRACON facility is responsible for guiding aircraft into and out of Newark and Philadelphia airspace.
By 1 p.m. ET, the disruption expanded across the New York metropolitan region, with the FAA halting incoming flights into John F. Kennedy International Airport and LaGuardia Airport.
According to tracking data from FlightAware, roughly 250 flights arriving at and departing from Newark were delayed, representing more than one-fifth of the airport's scheduled operations for the day. Newark serves as United Airlines' busiest international hub; the carrier waived ticket change fees for affected travelers.
Flightradar24 reported that as of roughly 1 p.m. ET, 67 flights scheduled to land at Newark were diverted to alternate airfields. The diverted traffic included international flights originating from Iceland, Egypt, Greece, Spain, and France. A United flight from Berlin was rerouted to Detroit Metropolitan Wayne County Airport, while an SAS flight from Stockholm bound for Newark was diverted to Washington Dulles International Airport.
Aging technology and air traffic control infrastructure have remained long-running challenges for commercial carriers. Last year, the Trump administration announced a multibillion-dollar modernization initiative aimed at overhauling U.S. air traffic control equipment and resources.
On the same day as the outage, the Department of Transportation and the FAA introduced a new artificial intelligence-powered analytics tool intended to evaluate operational data and minimize flight delays, with an initial rollout in Washington, D.C.
