FAA Halts Every Departing Flight In America After Air Traffic Control Communications Fail

A nationwide halt, Friday afternoon

The Federal Aviation Administration ordered a nationwide ground stop on Friday afternoon, Nov. 13, 2026, halting departing flights at every airport in the United States. The agency said the stop followed communication problems hitting multiple Air Route Traffic Control Centers, the facilities that direct high-altitude traffic across broad regions of American airspace and hand planes off from one region to the next.

Hundreds of flights were disrupted within the window the order took effect, according to CNBC. An internal message from Alaska Airlines, reviewed by the network, described the trigger as a mix of communications and radar issues striking the control centers at roughly the same time — language that pointed airline operations staff toward a systems problem rather than weather or a single airport outage.

FAA technicians were sent to investigate as soon as the stop went into effect. As of Friday afternoon, the agency had not given a timetable for restoring normal departures, and it had not said whether the cause had been identified.

What a ground stop actually does

A ground stop is a narrower tool than a full airspace shutdown, and the distinction matters for anyone trying to gauge how serious Friday's order really was. It freezes departures at their point of origin — a plane scheduled to take off simply doesn't, until the agency lifts the order — while flights already airborne keep flying under normal air traffic control guidance.

That means Friday's disruption, while sweeping, is not the same as closing American airspace outright. It is, instead, every airport in the country being told at once to hold its outbound traffic on the ground. The FAA does not reach for that tool often, and when it does, the cause tends to be systemic rather than local — a single bad-weather system or one airport's equipment failure rarely triggers a stop that covers the entire country.

"The FAA issued a nationwide ground stop for all U.S. airports following communication issues impacting multiple Air Route Traffic Control Centers," — Federal Aviation Administration, in a statement reported by CNBC.

Who was grounded, and who wasn't

The order covered domestic departures at every U.S. airport, meaning travelers waiting to take off were affected no matter where in the country they were flying from.

Inbound international flights were handled differently. The FAA said those arrivals would be managed case by case rather than placed under a blanket halt, which meant some planes already in the air and headed toward the United States from abroad kept flying while the agency worked through the scope of the problem on the ground.

The Alaska Airlines message reviewed by CNBC is the clearest early account of what airlines themselves were being told about the cause. It pointed to radar and communications issues tied to the control centers — not to a single airport, a single airline's own systems, or weather.

What the FAA said, on the record

The agency's own statement, issued Friday and reported by CNBC, was direct about both the cause and the scope: "The FAA issued a nationwide ground stop for all U.S. airports following communication issues impacting multiple Air Route Traffic Control Centers."

On what caused the failure, the agency said only that the matter was under active review: "FAA technicians are investigating the issue."

Those two sentences are, so far, the full extent of what the FAA has said publicly. The agency has not identified which control centers were affected, what in the communications or radar systems failed, or how long it took controllers to recognize the problem once it began.

How rare this really is

Nationwide ground stops are not a routine tool, and the FAA's own framing of Friday's order leaned on that history. The agency last ordered one in January 2023, when a failure in the Notice to Air Missions system — the alert system pilots check before every flight for runway closures, equipment outages and other hazards — forced a freeze on departures across the country.

Before that, the FAA had not grounded departing traffic nationwide since the Sept. 11, 2001, terrorist attacks, when the agency shut down American airspace entirely in response to the hijackings that day. Friday's order was triggered by a communications and radar failure rather than an act of violence, but it now sits alongside those two events as one of only a handful of times the system has stopped the entire country from taking off at once.

What travelers are being told

Airlines were already notifying their own operations teams before the FAA's public statement went out, as shown by the Alaska Airlines message CNBC obtained. That pattern — carriers hearing from internal operations centers before a formal agency statement reaches the public — is typical of fast-moving system failures like this one.

The FAA has not released passenger-facing guidance beyond confirming the stop and the investigation. Travelers with existing bookings are, for now, left watching the same two channels covered above: the FAA's own statements and updates from individual airlines about specific flights and airports.

What happens next

The FAA has not said when departures will resume nationally or what caused the communications and radar failure at the affected control centers. Technicians remained on the investigation as of Friday afternoon; airlines are expected to issue their own updates to ticketed passengers as the ground stop continues, and the FAA is expected to update its public guidance once departures begin to resume.
