The FAA ground stop brought flight departures across the United States to a halt on Friday, November 13, 2026, after a widespread communication failure affected air traffic control operations nationwide.
The Federal Aviation Administration issued the emergency order Friday afternoon, directing airports to suspend departing flights while technicians investigated the disruption. The agency described the situation as occurring “due to extraordinary circumstances and for reasons of safety.”
The sweeping decision affected airports across the country, including major travel hubs handling thousands of daily passengers. Travelers preparing to depart were left facing unexpected delays as airlines awaited further instructions from federal aviation officials.
According to the FAA advisory, aircraft operators were notified “by order of the Federal Aviation Command Center” that departing traffic must remain grounded “until further notice.”
Transportation Secretary Sean Duffy confirmed that the FAA ground stop followed “a communication issue impacting all Air Route Traffic Control Centers.”
“FAA technicians are investigating the issue. We will provide immediate updates as we have them,” Duffy said.
The disruption initially became apparent in Chicago, where O’Hare International Airport and Midway International Airport were placed under ground stops because of reported equipment outages. The restrictions were subsequently expanded nationwide as officials addressed the wider communications problem.

Both Chicago airports serve as important connections for travelers moving between major American cities. Interruptions at either location can affect flights scheduled to continue to destinations throughout the country.
However, Friday’s FAA ground stop extended far beyond Chicago, preventing departures throughout the national aviation system.
The emergency order primarily affected planes waiting to take off. Aircraft already in the air were permitted to continue toward their destinations, meaning the directive did not require every airplane currently flying to land immediately.
International arrivals received separate consideration.
“Inbound international flights will be managed on a case-by-case basis,” the FAA advisory stated.
That provision allowed officials to evaluate arriving international flights individually rather than automatically applying the same restrictions to every aircraft approaching the United States.
The situation created uncertainty for passengers who had already boarded aircraft, travelers waiting at departure gates and people preparing to leave for airports.
Because airlines operate interconnected schedules, the effects of a nationwide interruption can continue even after departure restrictions are removed. Aircraft arriving late may be needed for subsequent flights, while crews can encounter scheduling complications as delays accumulate.
The FAA ground stop also raised immediate questions about how long normal air travel operations would remain interrupted.
Federal officials had not established a publicly confirmed restoration timeline in the initial reports. The agency’s safety directive required aircraft operators to await clearance before resuming affected departures.
For travelers, that means a flight’s scheduled departure time may not accurately reflect when the aircraft will actually leave. Passengers should check directly with their airline for updated departure information, gate assignments and potential itinerary changes.
The nationwide grounding is an especially rare aviation emergency.
On January 11, 2023, the FAA temporarily suspended domestic flight departures after a failure involving its Notice to Air Missions system, commonly called NOTAM. That system delivers essential safety information to pilots, including notices about airport conditions, runway restrictions and other potential hazards.
The 2023 disruption lasted less than two hours before the nationwide order was lifted, although delays continued after flights were cleared to resume.
An FAA investigation later determined that contract personnel had unintentionally deleted files while attempting to correct synchronization problems involving the system’s databases.
The FAA ground stop on November 13, 2026, involves a different reported problem: communications affecting air traffic control centers rather than a confirmed NOTAM failure.
The incident comes as federal officials continue efforts to modernize the country’s aging aviation infrastructure.
Earlier in November, the Transportation Department announced work to replace outdated information systems used by air traffic controllers. Federal officials have also sought additional funding to upgrade equipment and improve the reliability of the nation’s air traffic control network.
Congress previously approved $12.5 billion for modernization efforts, while the FAA and White House requested an additional $30.1 billion on Friday for further aviation improvements.
Authorities have not established whether any specific aging equipment or modernization project contributed to the latest communications disruption.
The FAA has also not identified a confirmed cyberattack, sabotage or other deliberate interference as the cause of Friday’s emergency. The publicly disclosed information identifies a communications issue, but its precise technical origin remains under investigation.
As the FAA ground stop disrupts travel plans nationwide, passengers are being encouraged to monitor airline notifications and official aviation updates rather than rely solely on their original flight schedules.
