FAA Ground Stop: How Long Will Delays Last? Lessons From 2023

Quick Facts: The 2023 FAA Ground Stop

• Flights stopped shortly after 7 a.m. The FAA halted nationwide departures on January 11, 2023.

• The ground stop lasted less than two hours. The FAA lifted the order shortly before 9 a.m. Eastern, allowing departures to resume.

• More than 1,000 flights were canceled by 11 a.m., roughly two hours after the ground stop ended.

• Over 10,000 flights were disrupted by late that night. FlightAware recorded 8,783 delays and 1,276 cancellations.

• Airlines expected recovery the following day. Carriers anticipated normal operations by Thursday, January 12.

• Nationwide ground stops are exceptionally rare. Before Friday, the only others were on September 11, 2001, and January 11, 2023.

What Happened With the FAA Ground Stop on November 13?

The FAA ordered a nationwide ground stop at 3:54 p.m. Eastern after communication problems hit multiple Air Route Traffic Control Centers, the facilities that guide planes between airports.

In a pinned post on X, the FAA called it a temporary telecommunications outage and said every flight had been accounted for, and officials said there was no sign of a cyberattack. By about 7 p.m. Eastern, the FAA was gradually lifting restrictions as systems came back online, but FlightAware had already counted 10,243 delays and 3,535 cancellations of flights within, into, or out of the US.

What Happened During the 2023 FAA Ground Stop?

The trouble began the evening before. On January 10, 2023, the FAA's Notice to Air Missions system, known as NOTAM, failed. It gives pilots essential safety information, including runway closures and equipment outages, and without it the FAA couldn't be sure pilots had what they needed before departure.

When the problem still wasn't fixed the next morning, the FAA halted domestic departures nationwide shortly after 7 a.m. Eastern, the first shutdown of its kind since the September 11 attacks. Flights already in the air continued, while everything else stayed on the ground.

Technicians restored the system, and the FAA lifted the order shortly before 9 a.m. The ground stop had lasted less than two hours, but airline schedules across the country were already in disarray.

What Happened After Flights Started Moving Again?

The disruption kept growing after the ground stop ended. By 11 a.m., two hours after departures resumed, more than 1,000 flights had been canceled, and by late that night FlightAware had recorded 8,783 delays and 1,276 cancellations.

Airline schedules couldn't simply pick up where they left off. Planes were hours behind, so a delayed flight from New York to Chicago could push back that aircraft's next departure to Denver and every flight after it.

After a ground stop ends, airlines still have to clear the backlog of planes, crews, and passengers waiting to leave.

Airline schedules couldn't simply pick up where they left off. Planes were hours behind, so a delayed flight from New York to Chicago could push back that aircraft's next departure to Denver and every flight after it.

Crews were another problem. Pilots and flight attendants have strict duty-time limits, and some ran up against them while waiting, so airlines had to find replacements and reposition aircraft. Even passengers whose flights weren't part of the original ground stop could end up delayed later in the day.

How Long Did It Take Airlines to Recover in 2023?

Despite the scale, the recovery was quick. By Wednesday evening, airlines said they expected normal operations on Thursday, January 12, and the next morning looked considerably better, though travelers with canceled flights still had to hunt for open seats.

The timing helped. Because the ground stop ended before 9 a.m., airlines had most of Wednesday to reposition aircraft and rebook passengers. That's why the timing of a ground stop can matter almost as much as the technical failure itself.

What Did Investigators Eventually Discover?

While airline operations recovered relatively quickly, the investigation took longer. The FAA initially identified a damaged database file but needed more time to determine what caused the failure and why backup systems hadn't prevented it.

On January 19, eight days after the shutdown, the FAA revealed that contractors had unintentionally deleted files while correcting a synchronization problem between the primary NOTAM database and its backup. Investigators found no evidence of a cyberattack or malicious intent.

The findings raised questions about how routine maintenance could trigger a nationwide shutdown. The FAA introduced additional safeguards, strengthened oversight of database work, and restricted system access for personnel involved in the incident.

The lesson for November 2026 is that identifying an affected system doesn't necessarily explain why it failed. In 2023, the fuller explanation didn't emerge until days after flights resumed.

Could the November 2026 FAA Ground Stop Follow the Same Pattern?

The 2023 shutdown is a useful comparison, but the two incidents are different. In 2023, the FAA had to restore a pilot-notification database. Friday's outage hit communications at multiple Air Route Traffic Control Centers, which manage planes traveling between airports.

That changes how recovery works. The FAA said it was gradually lifting restrictions as systems came back online, so flights are being released in stages rather than all at once.

Friday's outage hit Air Route Traffic Control Centers, the facilities that guide planes between airports.

Timing is the other challenge. The 2023 ground stop ended early on a Wednesday, leaving airlines most of the day to recover. Friday's started late in the afternoon, heading into a busy weekend, which leaves fewer hours to reposition planes and crews before Saturday morning's flights.

It also took longer to fix. The FAA began lifting restrictions about three hours after the ground stop started, compared with under two hours in 2023, so the backlog is bigger. That makes 2023 a good guide to how disruptions spread, but not an exact forecast.

What Travelers Should Expect Over the Next 24 to 48 Hours

The biggest lesson from 2023 is that planes taking off again doesn't mean the system has recovered. Airlines may still have aircraft in the wrong cities, crews near their duty limits, and thousands of passengers trying to rebook.

Travelers flying Saturday or Sunday could see delays or cancellations even if their flights weren't scheduled during Friday's ground stop. A plane needed Saturday morning may never have arrived Friday night, and open seats for rebooking may be limited on popular routes.

That doesn't mean every flight this weekend will be affected. In 2023, things were already much better the next morning, so watch whether cancellations keep climbing and what your airline says about its schedule.

So, How Long Could This Last?

The 2023 shutdown offers some perspective, and a little reassurance. The FAA stopped departures for less than two hours, the disruption lasted the rest of the day, and by the next morning things had improved considerably.

Whether this weekend follows the same pattern depends on how quickly the communications problem is fully resolved and how big the backlog gets. Keep plans flexible, watch your airline's updates, and remember that the first planes taking off are only the beginning of the recovery.

In 2023, the ground stop ended within hours. Getting the airlines back on schedule took longer, and understanding what went wrong took longer still.

Check your airline's app before heading to the airport, since FAA ground stop have affected all US flights.

Frequently Asked Questions: FAA Ground Stops and Flight Recovery

How long did the 2023 FAA ground stop last?

How many flights were affected by the 2023 FAA outage?

By late January 11, FlightAware had recorded 8,783 delays and 1,276 cancellations, affecting more than 10,000 flights nationwide.

How long did it take flights to return to normal in 2023?

Airlines expected operations to largely return to normal on January 12, the day after the shutdown, although some passengers continued dealing with cancellations and missed connections.

What caused the 2023 FAA ground stop?

The FAA's preliminary investigation found that contract personnel unintentionally deleted files while correcting a database synchronization problem. Officials found no evidence of a cyberattack or malicious intent.

Is the November 2026 FAA outage the same as the 2023 outage?

No. The 2023 failure involved the FAA's NOTAM pilot-notification system. The November 2026 shutdown reportedly involves telecommunications affecting air traffic control centers.

Will flights still be delayed after the FAA lifts the ground stop?

They can be. Airlines may need additional time to reposition aircraft, arrange crews, and accommodate passengers whose original flights were canceled.

Can I get a refund if my flight is canceled?

Yes. If an airline cancels your flight and you decline alternative transportation or travel credit, you're generally entitled to a refund under U.S. Department of Transportation rules.
