FAA orders airlines to pause domestic US flights amid a system outage

• The FAA has ordered airlines to pause their domestic departures after a system outage.
• The FAA said it expects departures to resume at 9 a.m. Eastern Time.

The Federal Aviation Administration (FAA) has ordered airlines to pause their domestic departures from the US until 9 a.m. Eastern Time.

The FAA is experiencing an issue with its Notice to Air Missions (NOTAM) system, leading to flight delays and cancellations.

The agency said in a statement: "The FAA is still working to fully restore the Notice to Air Missions system following an outage.

"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."

United Airlines confirmed in a statement shared on social media that they had "temporarily delayed all domestic flights."

The temporary ground stop excludes military and medevac flights, per an FAA update.

The agency said in a statement that departures had already resumed at Newark Liberty and Atlanta Hartsfield-Jackson airport due to air traffic congestion.

The White House press secretary, Karine Jean-Pierre, said President Biden had been briefed by the secretary of transportation on the outage. Jean-Pierre added that there is no evidence of a cyberattack at this point, but the president directed DOT to conduct a full investigation into the causes.
