Airlines cancelled more than 5,900 flights and delayed over 7,000 others across the United States on Saturday as the national aviation network struggled to recover from a four-hour nationwide ground stop.
FAA Ground Stop Causes Massive Flight Cancellations
The Federal Aviation Administration issued the nationwide ground stop Friday shortly after 1 p.m. Pacific Standard Time due to a massive communications failure affecting all 22 Air Route Traffic Control Centers. Nearly all departing flights were halted. The stop lasted for roughly four and a half hours.
There is a pot of 60 billion extra dollars on top of the regularly appropriated amount for ICE and we should use at least a portion of that money for the FAA. We can solve this problem and not spend any additional taxpayer dollars.
It created one of the worst travel days in U.S. history and forced airlines to cancel nearly 10,000 flights and delay more than 7,000 others on Friday alone. Operations continued to face widespread disruptions over the weekend, stranding tens of thousands of passengers in airports and postponing college sports games.
By Sunday morning, about 5 percent of flights—more than 1,300 trips—had already been canceled. Nearly 90 percent of all flights left within 14 minutes of their scheduled departure time, according to data from aviation analytics company Cirium. Tracking website FlightAware reported 17,670 delayed flights and 2,218 canceled flights nationwide by late Sunday morning, including 246 delays and 73 cancellations at Los Angeles International Airport.
You’ve literally controlled Congress for the past two years. And apparently, there’s always been money for vanity projects. But none to fix our air traffic control system? Perhaps Trump should prioritize aviation safety over his pathetic Arch. https://t.co/MiiasllRiM
Major hubs from Atlanta and Dallas to Phoenix and Philadelphia experienced significant logjams as airlines worked to reposition flight crews and aircraft. Federal Aviation Administrator Bryan Bedford apologized for the disruption and said that the system was stable.
Bryan Bedford said that the system was stable. He expected airline operations to largely return to normal by late Sunday.
Router Failure During Telecommunication Upgrade
Investigators traced the root cause of the shutdown to an equipment upgrade at a remote facility in El Dorado, Arkansas. Contractor L3Harris was switching old copper telecommunication lines to fiber-optic cables there. Transportation Secretary Sean Duffy explained that a computer router installed during the maintenance process began sending out faulty signals that flooded the agency’s network.
We had over 1,000 connection attempts every four to five seconds, and what that did was (it) gave us issues with our communication with airplanes, and also caused some disruption with our radar.
Sean Duffy, U.S. Transportation Secretary
The data overload affected communications at 17 of 22 en route centers. This prompted the agency to order the ground stop as a safety precaution. Officials said that no facilities went dark and no communications were fully lost.
Federal investigators examined the hardware at an L3Harris lab in Florida, and the Federal Bureau of Investigation offered assistance. Administration officials confirmed they found zero evidence of a foreign cyberattack or an artificial intelligence-related mishap.
“It will be the BEST SYSTEM anywhere in the World. Much of our current air control system is 50 years old – RIDICULOUS! We have already started the work, but it should be done all at once, not in drips and drabs,” President Donald Trump said in a post on Truth Social on Sunday.
We see zero evidence of anything nefarious, and zero evidence of anything AI-related. So we want to be clear that we have a equipment issue, and we’re working through what this defective piece of equipment was.

Duffy Requests $50 Billion to Overhaul Air Control Network
In the wake of the airspace meltdown, Duffy implored Congress to authorize $50 billion in funding to overhaul the air control network, increasing his previous request of $30 billion. President Donald Trump urged lawmakers on social media to approve the funds quickly, saying that the current infrastructure is decades old.
However, congressional Democrats countered that the agency already holds sufficient unspent funds. Under a spending and policy bill passed by Republicans last year, the agency received $12.5 billion, with $4.75 billion allocated specifically for telecommunications infrastructure modernization and systems upgrades.
“The system needs a complete overhaul,” Transportation Secretary Sean Duffy said.
I have no money in that $12.5 billion that I can use for a new architecture for telecom. I can’t build new software to manage our airplanes in the airspace because it dates back to the 1990s, but there’s no money for that.
Sean Duffy, Transportation Secretary
House Appropriations Committee top Democrat Rosa DeLauro criticized the revised financial appeal as a ransom demand, while other lawmakers questioned why the administration prioritized other federal projects over aviation modernization. Meanwhile, outgoing House Speaker Mike Johnson said on Fox News that Republicans would add Federal Aviation Administration funding to an upcoming legislative package as appropriators negotiate a government funding deal ahead of a December 11 deadline.
