Northeast Flights Resume After FAA Telecom Outage, but Delays May Persist
Flights are moving again across the Northeast after a telecommunications failure at a Federal Aviation Administration facility disrupted air travel for hours on Monday, September 21, halting arrivals at several major airports and causing thousands of delays and cancellations nationwide.
The outage has been repaired, but the disruption may not clear as quickly. Travelers passing through Newark Liberty International Airport, John F. Kennedy International Airport, LaGuardia Airport, Philadelphia International Airport, and Boston Logan International Airport could still face delays and cancellations as airlines reposition aircraft, crews, and passengers.
"The telecom lines have been repaired, and all airport operations in the Northeast are resuming," Transportation Secretary Sean Duffy wrote on social media Monday evening. He added that "it will take some time to clear all existing delays."
By the end of Monday, roughly 7,000 flights around the United States had been delayed or canceled, according to FlightAware data. Newark was among the hardest-hit airports: commercial arrivals were halted for nearly eight hours, more than 600 flights into or out of the airport were canceled, and more than 100 flights bound for affected airports were diverted elsewhere.
The disruption stemmed from two overlapping technical failures. A primary telecommunications circuit at the FAA's Philadelphia air traffic control facility failed Monday morning. Normally, the system would have switched to a backup line, but officials discovered the backup fiber-optic cable had also been severed during railroad construction in New Jersey. That left controllers without access to some radar and communications systems used to safely manage aircraft. The FAA sharply limited traffic through the affected airspace, temporarily stopping arrivals at Newark, JFK, LaGuardia, Philadelphia, and Boston.
There was initially confusion over who damaged the backup cable. Duffy first said an Amtrak crew had cut it, but Amtrak denied involvement. New Jersey Transit later said work at one of its construction sites was likely connected to the damage and that it was investigating. The lines were repaired Monday evening, allowing air traffic to begin returning to normal.
Repairing the communications system is only the first part of the recovery. Airlines move the same planes and crews through tightly timed sequences each day. When that sequence breaks down for several hours, aircraft can end up hundreds of miles from where they are supposed to spend the night. Pilots and flight attendants can run up against federal duty limits and rest rules. Passengers who miss flights or connections suddenly need seats on later departures that may already be nearly full. That is why a disruption centered on the Northeast can appear elsewhere the next morning. A flight from Chicago to Denver, for example, may still be delayed if its aircraft was supposed to arrive from Newark the night before and never made it.
The FAA has not confirmed that delays will continue for days, but after a disruption of this size, airlines can take a day or two to fully rebuild schedules, particularly at busy hubs with little spare capacity to absorb thousands of displaced travelers.
Travelers flying through the Northeast should check their flight status in their airline's app before leaving for the airport, even if departure is still showing as on time. It is also worth checking the inbound aircraft, which many airline apps show. If the plane operating your flight is still several states away-or its earlier flight has already been delayed-that can be an early sign your departure may change.
Some airlines have issued travel waivers giving passengers more flexibility to move affected trips. United, which operates a major hub at Newark, issued one following Monday's disruptions, and other carriers have allowed some travelers to change flights without the usual penalties. If your airline is offering a waiver and your plans are flexible, shifting your trip by a day may be the simplest option, especially if your itinerary includes a tight connection at Newark, Philadelphia, or another airport still working through the backlog.
Travelers whose flights are canceled also have federal refund rights. If an airline cancels your flight and you decide not to accept the alternative transportation it offers, you are entitled to a refund. The same applies when a flight is significantly changed or delayed and you choose not to travel.
Hotel rooms and meals are less straightforward. Because Monday's disruption originated with air traffic control rather than the airlines themselves, passengers should not assume carriers will cover those costs. Airline commitments for meals, hotels, and ground transportation generally apply when a cancellation or delay is considered within the carrier's control, although individual airlines can choose to provide more assistance.
