First modification:
Hundreds of internal flights in the United States were canceled or delayed this January 11, after the Federal Aviation Administration (FAA) reported an interruption in its Air Mission Notification system. The aeronautical authority, which is investigating the ruling related to alerts to pilots and air personnel about dangers, incidents and procedures, gave the green light to the departure of flights after a two and a half hour break. The causes of the failure in the security system are being investigated.
An air chaos that begins to normalize. Hundreds of flights were grounded throughout the country after the Federal Aviation Administration (FAA) ordered operations to stop due to an interruption in its Air Mission Notification system. Two and a half hours after the failure, the aeronautical authority lifted the suspension of internal flights and little by little the flow that affected thousands of flights and travelers was restored.
The government agency explained that the ruling is related to the essential notices it issues to pilots and personnel involved in flight operations about dangers, changes in facilities and procedures at airports, functions that stopped processing updated information.
“The FAA has ordered airlines to suspend all domestic departures until 9:00 am Eastern time to allow the agency to validate the integrity of flight and security information (…) Operations throughout the National System of the Airspace are affected”, communicated the FAA in a first communiqué.
According to FlightAware air travel tracker, more than 2,500 domestic flights were delayed or canceled in the early morning hours of Wednesday, January 11.
Most of the delays were concentrated along the east coast, but they began to spread to the west.
International inbound trips to Miami International Airport continued to land initially. However, departures began to suffer delays from 6:30 am local time, according to the spokesman for the air terminal, Greg Chin.
The FAA gradually restores airflow
In its most recent update, the Federal Aviation Administration reported that “Air traffic operations are gradually resuming in the US following an overnight outage to the Notice to Air Missions system that provides safety information to flight crews.”
The aviation authority added that it is still investigating the cause of the problem.
Update 5: Normal air traffic operations are gradually resuming across the US following an overnight outage to the Notice to Air Missions system that provides safety information to flight crews. The ground stop has been lifted.
We continue to look into the cause of the initial problem

Previously, the agency noted that while some functions were starting to come back online, National Airspace System operations remained “limited.”
