All Domestic U.S. Flights Grounded

January 11, 2023

The FAA has ordered airlines to pause all domestic departures until 9 a.m. Eastern Time to allow the agency to validate the integrity of flight and safety information.

The Federal Aviation Administration announcing the grounding of all U.S. domestic flights. The Notice to Air Mission (NOTAM) system – which provides safety information for pilots – malfunctioned. Normal airport operations are resuming after about two hours of outages.

Why It Matters: As of early Wednesday morning, over 1,200 flights were delayed across the country. Because no departures were allowed until at least 9 a.m. ET, the number of delays and cancellations will likely continue to grow for the nearly 21,500 flights originally scheduled today.

The Latest: Around 9 a.m. ET, the Federal Aviation Administration announced that “Normal air traffic operations are resuming gradually across the U.S. following an overnight outage to the Notice to Air Missions system that provides safety info to flight crews. The ground stop has been lifted. We continue to look into the cause of the initial problem.”
