FAA orders nationwide ground stop after air traffic control communications failure

The US Federal Aviation Administration has ordered a nationwide ground stop after reporting serious air traffic control communications problems. The move came shortly after the agency halted traffic in Chicago, where departures were first paused because of the disruption. The FAA said the restriction was imposed due to extraordinary circumstances and for safety reasons.

The agency said all departing traffic should remain ground stopped until further notice. It added that international flights would be handled on a case-by-case basis. Flights already in the air may continue to land, but aircraft on the ground cannot take off while the order remains in place.

US Transportation Secretary Sean Duffy said the problem was a communication issue affecting all air route traffic control centres, and said FAA technicians were investigating. The scale of the response underlines the seriousness of the disruption to the national aviation system. The FAA said this is only the second nationwide ground stop in the United States since the September 11 attacks.

The last such pause came in January 2023, when domestic departures were stopped for less than two hours. The latest order affects a system that depends on continuous coordination between control centres, airlines and airports to keep traffic moving safely. The incident also has immediate implications for international travel, because the FAA said overseas flights would be managed individually.

That suggests the disruption could affect not only domestic departures but also inbound and outbound long-haul services, depending on operational decisions at the time. In practical terms, the ground stop can create delays across the network even if some aircraft are already airborne and able to land. The FAA has not yet said what caused the communications failure, and the exact scope of the technical problem remains unclear.

It is also not known how long the ground stop will last or when normal departures will resume. The key issue now is whether technicians can restore communications across the affected traffic control centres quickly enough to lift the restriction safely. For now, the incident stands as a rare nationwide intervention in US aviation, with Chicago as the first visible point of disruption before the broader order followed.

The investigation by FAA technicians will be central to determining whether the problem was isolated or systemic. Travellers and airlines will be watching for further guidance on departures, international handling and the timing of any restart.
