Salt Lake City airport halts all flights amid rare nationwide ground stop
The national ground stop was issued due to a “communication issue” affecting Air Traffic Control Centers, the U.S. Secretary of Transportation announced.
A nationwide ground stop was issued by the Federal Aviation Administration in response to a communications issue affecting air traffic control centers, according to statements cited by The Salt Lake Tribune and other outlets. The Salt Lake City International Airport halted all flights as part of the broader national action, described as rare and extraordinary, with authorities citing safety concerns tied to ATC communications as the root cause of the pause.
Multiple outlets report that the ground stop affected departures nationwide, including Detroit Metro Airport in Romulus, Michigan, and that aircraft already in flight would continue to their destinations under the last assigned clearances. The FAA described the move as an ATC Zero-style posture, where in-flight aircraft proceed under their existing clearances while new departures are withheld. This framing appeared in CBS News coverage and was echoed by Global News and Open Jaw in their summaries.
The situation was characterized as ongoing and evolving, with no immediately disclosed end time for the halt in the initial advisories. Authorities indicated that international arrivals would be handled on a case-by-case basis as the FAA investigates the underlying communications issue. Several outlets highlighted that the stoppage was temporary and subject to FAA guidance and updates as investigators work to determine a timeline for resuming normal operations.
Regionally, Chicago’s O’Hare International Airport stood out as a specific carve-out within the nationwide pause, with departures held from 1:00 p.m. to 2:15 p.m. local time due to thunderstorms in the area. Weather conditions were described as mostly cloudy with rain and thunderstorms in the vicinity, contributing to ongoing flight cancellations and delays at the hub. Some reports noted a possibility of extending the pause depending on evolving weather and the investigation.
Open Jaw’s reporting framed the incident as a nationwide, unprecedented interruption to the U.S. air-transport system, noting that the ground stop applied only to departures while aircraft already airborne would continue toward destinations under last clearances. The coverage repeatedly described the action as extraordinary safety measures and did not identify a specific trigger beyond general references to safety concerns and communications issues within ATC centers.
CTV News added that Canadian airports were affected by the U.S. FAA action, with Edmonton International Airport noting that several U.S.-bound departures could be impacted and travelers advised to check with their airlines. Montreal-Trudeau International Airport was reported as temporarily suspending flights to and from the United States in response to the nationwide stop, with delays and cancellations anticipated. The connection between the U.S. action and Canadian airports was presented as part of broader international disruption in several reports.
Across outlets, there was a consistent emphasis on there being no reported injuries, fatalities, or aircraft accidents related to the ground stop or the associated weather events in the early coverage. The stoppage was described as temporary, with the duration and end time to be determined by ongoing FAA updates and the results of the investigation into the communications issue at air traffic control centers.
CBS News, Global News, and ABC7 Bay Area all reported that the FAA’s directive affected outbound departures across U.S. airports, while international arrivals would be handled on a case-by-case basis as the agency assessed the evolving situation. The CBS and Global coverage also highlighted that airlines and travelers were advised to verify schedules and expect cascading delays while the halt remained in place, with updates expected as the FAA investigation progressed.
