As the Federal Aviation Administration (FAA) rushed to fix a system disruption on Wednesday, US flights were grounded or delayed. Passengers were advised to check with airlines for updates.
The FAA announced that it has instructed airlines to halt all domestic departures until 9 a.m. ET (1400 GMT) in order to give the organization time to confirm the accuracy of flight and safety-related data.
Existing flights were permitted to go on to their destinations. The FAA reported that it was trying to fix a system that had stopped processing updated information and warning pilots of hazards and changes to airport facilities and procedures.
The Notice to Air Missions (NOTAM) system is still being fully restored by the FAA after an outage. “National Airspace System operations remain constrained, despite the fact that some functions are starting to resume,” the FAA stated on Twitter.
According to the flight tracking service FlightAware, as of 7:19 am ET (12:19 GMT), 1,230 aircraft were either delayed within, into or out of the United States. 103 other flights within, outside, or both directions were also canceled.
During premarket trade on Wednesday, shares of American carriers decreased. Delta Air Lines, United Airlines (UAL.O), and American Airlines (AAL.O) all saw declines of less than 1%, while Southwest Airlines saw a 2.4% decline.
A NOTAM is a message that contains information that is crucial to those involved in flight operations but is not known far enough in advance to be made public in any other way.
For long-haul international flights, the information can be up to 200 pages long and may include things like runway closures, bird hazard warnings, and construction barriers. All domestic flights have been temporarily delayed, according to United Airlines, which added that it would provide an update as it received further information from the FAA.
While the French carrier said it was keeping an eye on the situation, Lufthansa of Germany and Air France both stated that they were still running flights to and from the United States. The Austin-Bergstrom International Airport tweeted that delays were being caused by ground stops around the nation. An air traffic control measure known as a ground stop delays or stops airplanes at a certain airport.
The FAA stated that its NOTAM system had “failed” in a previous notice on its website, despite the fact that NOTAMs published prior to the outage could still be viewed.
According to data from Cirium, a total of 21,464 planes with a carrying capacity of over 2.9 million people are scheduled to leave airports in the United States on Wednesday.
According to Cirium statistics, American Airlines has 4,819 booked flights that will depart from American airports, followed by Delta Air Lines and Southwest Airlines.
