FAA Computer Outage Results in Widespread Domestic Delays

By Donna M. Airoldi / January 11, 2023 / Contact Reporter
Business Travel News on X

[Update: Jan. 12, 2:15 p.m. ET]

The tally of canceled U.S. flights Wednesday reached 1,353, with 10,942 delayed after the day started with a ground stop from the FAA, according to aviation tracker Flight Aware. Yesterday’s stoppage was the first time the FAA ordered a national ground stop since the terrorist attacks of Sept. 11, 2001. Operations are running more smoothly today, with  124 cancellations and 2,336 delays for flights within, into or out of the U.S. as of 2:10 p.m. The four top U.S. carriers had delay rates of 10 percent or lower at that time and practically no cancellations.

[Update: Jan. 11, 2:15 p.m. ET]

The Federal Aviation Administration's Notice to Air Missions system suffered a nationwide outage earlier today, causing hundreds of flight delays, cancellations and ripple effects outlasting the technology breakdown.

This update adds a response from Southwest Airlines. The carrier has resumed operations after the FAA lifted its ground stop. As a result of the outage, Southwest anticipates schedule adjustments will be made throughout the day, has posted a travel advisory on its website and is encouraging customers to check flight status on the Southwest app or its website for changes prior to arriving at the airport. 

The carrier also is allowing those customers traveling today, Jan. 11, to rebook in the original class of service or to travel standby within 14 days of the original date of travel between the original city-pairs and in accordance with Southwest's accommodation procedures, without paying additional charges. 

Southwest, through a spokesperson, also said that the company is fully staffed and focused on operating as many flights as possible today, though it expects delays because of the FAA ground stop that pushed the departure of its first East Coast flights by two to three hours. Before the FAA ground stop was lifted, Southwest proactively canceled flights early to begin reaching customers with updates and flexibility to self-serve changes to their travel plans.

Update Wednesday, Jan. 11 at 1 p.m. ET _______________________

The Federal Aviation Administration's Notice to Air Missions system suffered a nationwide outage earlier today, causing hundreds of flight delays, cancellations and ripple effects outlasting the technology breakdown.

As of early afternoon, flights have resumed but with continued cancellations and delays across the country. 

In addition to United's waiver and refund offer, American is "providing additional flexibility to rebook their travel plans today and tomorrow without any additional fees," according to an American spokesperson. Delta is offering a "fare difference waiver" to all Delta and Delta Connection flights on Wed., Jan. 11, and "will give customers additional flexibility to change their flights, even if their flight isn't delayed or canceled," according to a posting on Delta's website. 

Delta also noted that it was working with the FAA on "strategic delay programs" at certain airports throughout the day in order to prevent further congestion on the ground and to make sure there was enough available gate space at airports, according to the carrier. Still, "potential for additional delays and cancels continue," according to Delta.

Southwest Airlines had not yet responded to a request for information at the time of publication. 

As of 1 p.m., based on scheduled flights for today, the percentage of cancellations and delays continued to grow for each of the following four carriers, according to Flight Aware. There so far have been a total of 7,539 delays and 1,163 cancellations for flights within, into or out of the United States.

Southwest had 377 cancellations (9 percent) and 1,813 delays (47 percent). American had 183 cancellations (6 percent) and 1,232 delays (41 percent). United had 68 cancellations (3 percent) and 739 delays (32 percent). And Delta had 58 cancellations and 1,042 delays (36 percent). 

Despite Flight Aware's total of 58 cancellations, Delta noted in a statement that it had to cancel more than 130 Delta and Delta Connection flights "after all other options were exhausted."

Update Wednesday, Jan. 11 at 10:10 a.m. ET _______________________

The Federal Aviation Administration's Notice to Air Missions system, which sends out real-time flights hazards and restrictions to all commercial airline pilots, suffered a nationwide outage earlier today.

The U.S. Travel Association president and CEO Geoff Freeman commented on the FAA outage this morning:

"Today's FAA catastrophic system failure is a clear sign that American's transportation network desperately needs significant updates," Freeman said in a statement. "Americans deserve an end-to-end travel experience that is seamless and secure. And our nation's economy depends on a best-in-class air travel system. We call on federal policymakers to modernize our vital air travel infrastructure to ensure our systems are able to meet demand safely and efficiently."

As of 10:10 a.m., there were 5,417 flight delays within, into or out of the United States, and 907 cancellations, according to Flight Aware. Southwest of its scheduled flights had 328 cancellations (8 percent) and 1,664 delays (43 percent). American had 172 cancellations (5 percent) and 772 delays (26 percent). Delta had 37 cancellations (1 percent) and 690 delays (24 percent). United had 29 cancellations (1 percent) and 512 delays (22 percent).

Update Wednesday, Jan. 11 at 9:23 a.m. ET _______________________

The Notice to Air Missions system, which sends out real-time flights hazards and restrictions to all commercial airline pilots, suffered a nationwide outage earlier today, according to the U.S. Federal Aviation Administration.

While some functions have begun to come back online, the FAA was still working to fully restore the system. The agency had ordered airlines to "pause all domestic departures" until 9 a.m. Eastern Time to allow the FAA to "validate the integrity of flight and safety information." But by 8:15 a.m., departures had resumed at Newark Liberty International Airport and Atlanta Hartsfield-Jackson International Airport, according to the FAA.

By 8:50 a.m., normal air traffic operations had begun to gradually resume across the United States, according to the FAA, which has lifted the ground stop.

The agency said it will continue to look into the cause of the initial problem.

The number of flights delayed so far today by 9 a.m. was 4,013 according to aviation tracker Flight Aware. Southwest Airlines had 1,677 or 44 percent of its schedule delayed, American Airlines had 522 or 17 percent of its schedule delayed, Delta Airlines had 466 or 16 percent delayed, and  United Airlines had 313 or 13 percent of its flights delayed, according to the tracker. 

Airlines are cautioning that delays and cancellations could continue to ripple through their schedules. United has issued a statement that it is working to restore its schedule and has activated a travel waiver for any customers who need to change their plans, including offering refunds for customers who no longer want to travel.
