FAA Halts All US Departures Amid Nationwide Communication Failure

Key points

• The FAA issued a nationwide ground stop for all departing flights on November 13, 2026, citing 'extraordinary circumstances' and safety concerns.
• Transportation Secretary Sean Duffy attributed the halt to a communication issue impacting all Air Route Traffic Control Centers, which manage flights above 18,000 feet.
• This is the second nationwide ground stop since September 11, 2001; the last occurred in January 2023 when the Notice to Air Missions system failed.
• FAA technicians are currently investigating the issue, with the agency promising immediate updates as information becomes available.
• Inbound international flights are being handled on a case-by-case basis, while all departing traffic remains grounded until further notice.

Background

This event follows a series of recent aviation disruptions, including a private jet skid at Las Vegas in October 2026 and a Southwest engine diversion in November 2026. It also occurs shortly after the FAA proposed new regulations to streamline commercial launches in November 2026. The last nationwide ground stop was in January 2023, caused by a failure in the Notice to Air Missions system, which prevented pilots from receiving pre-departure paperwork. Prior to that, the only other nationwide halt was following the September 11, 2001, terrorist attacks.

How outlets are covering it

ABC News and NBC News both reported the ground stop as a response to a communication issue affecting air traffic control, with ABC News noting that pilots in the air are prepared to continue their flight paths. Bloomberg confirmed the halt but focused on the official advisory notice. All sources agreed on the 'extraordinary circumstances' rationale, but ABC News emphasized the rarity of the event since 2001, while NBC News highlighted the lack of detailed information in the initial alert. No source reported on the specific technical nature of the communication failure beyond it affecting all Air Route Traffic Control Centers.

Why it matters

A nationwide ground stop severely disrupts air travel, affecting thousands of passengers and potentially causing significant economic losses for airlines and related industries. It highlights vulnerabilities in the nation's air traffic control infrastructure and the potential for widespread disruption from technical issues. The rarity of such an event underscores the critical importance of robust communication systems in aviation safety.

What to watch

FAA technicians are investigating the communication issue, and the agency has promised immediate updates. The ground stop will remain in effect until further notice, with inbound international flights being managed case-by-case. Airlines and passengers should expect significant delays and cancellations until the issue is resolved and the FAA lifts the ground stop.
