The nationwide ground stop at U.S. airports is lifted. The cause is tied to a communications line cutover, and there is no evidence of an attack

What you should do

Airline-by-airline notices are listed in the Airline notices section of this page. Check the notice from the airline you are flying
To check on family or colleagues in the U.S., enter the flight number on the airline's website or in the Flightradar24 or FlightAware app. After landing, you may be unreachable while they go through immigration
Connecting flights within the U.S. are seeing many delays and cancellations. Check rebooking in the airline's app (Delta and United are offering free changes)
Flights from the U.S. to Japan may depart late. Check the flight status before heading to the airport
If an email or text message urges you to "start your rebooking here," check it in the airline's official app or website before opening the link

Disaster news for each company

This page reads the same for everyone

But who in your company is on a business trip in the U.S. right now, which flight they are on, and how their connections work out differ from company to company. We have begun using agents to create company-specific disaster news that matches this against your company's map and delivers a version written for each employee.

For companies, and for individuals through "My Disaster Preparedness News," we will announce it in our newsletter once we have decided how to start.

What we know, what we don’t know yet, and what is being done

What we know

According to the Transportation Secretary, the stop came after the contractor L3Harris had been switching communications lines at a remote FAA facility from old copper wire to fiber optic. It is not yet known whether the cause was a work error or an equipment failure (CNN, CNBC)
FAA Administrator Bedford said there was "zero evidence of anything malicious, zero evidence of anything involving AI." Up to 17 of the 22 air route traffic control centers were affected, but no facility went down. Departures were halted because the flow of information had become unstable
Of the 170 passenger flights between Japan and the U.S. scheduled to depart from 6 p.m. on November 13 to midnight on November 15, 2 were canceled (UA32 and UA33), 18 were delayed by two hours or more, and none were diverted. 164 have arrived and 4 are in the air (10:50 a.m. JST, November 15, FlightAware)
Of the 62 Japan-U.S. passenger flights scheduled to depart after 3:00 p.m. on November 14, 2 are delayed 2+ hours (DL294, UA882) and 1 is canceled (UA33). Delays on flights from the evening onward have eased (10:06 p.m., FlightAware)
The Transportation Secretary said at a White House news conference that unless the air traffic control system is modernized, "this will happen again" (ABC News)
Of all 170 flights between Japan and the U.S. (passenger flights scheduled to depart from 6 p.m. on November 13 to midnight on November 15), 2 were canceled (UA32 and UA33), 18 were delayed by two hours or more, and none were diverted (7:10 p.m. JST, FlightAware)
The FAA lifted the nationwide ground stop at 10:15 a.m. JST. At about 4 hours 20 minutes, it was the longest since 9/11 (Flightradar24, Reuters)
An estimated 1.5 million people were stranded (Cirium). On Saturday, November 14 (ET), 3,374 flights were canceled by 6 a.m. (8 p.m. JST). Cancellations since Friday total 12,506 flights (FlightAware, ABC News)
A U.S. government official explained that new technology added to the air traffic control system strained old equipment, causing communications and radar to cut in and out (AP)
The Transportation Secretary said the switches and routers were overloaded, began producing conflicting data, and stopped. Recovery is slow and depends on how crews can be repositioned
Halting departures nationwide is very rare; the previous cases were the September 11, 2001 terrorist attacks and a system failure in January 2023. Delays exceeded 10,000 flights and cancellations exceeded 3,000 (FlightAware, 6:40 p.m. ET on November 13)
At 5:54 a.m. JST on November 14, the FAA halted departures at all U.S. airports. Flights already in the air may land at their destinations, and international flights arriving in the U.S. are decided flight by flight (FAA advisory 111)
The reason is a communications failure that reached the Air Route Traffic Control Centers. The FAA called it a "temporary communications outage" and said it "knows the location of all flights" (around 7:02 a.m.)
The U.S. Secretary of Homeland Security said there is "no indication so far that this was a malicious act." The U.S. government and Microsoft both deny any link to the Microsoft 365 outage the previous day
All 35 flights to the U.S. that left Japan from November 13 to the early hours of November 14 (flights our editors checked) took off before the stop and reached their scheduled airports (one was just before landing). No flights were diverted
From 8 a.m., the FAA began allowing departures in stages. San Francisco was cleared for Pacific departures such as Hawaii and Asia, and Boston for some Atlantic departures

What we don’t know yet

How many Japanese nationals are stranded in the U.S.
The day normal operations resume (expected to take several days)
Whether it was a work error in the cutover or an equipment failure (under investigation)
How many flights between Japan and the U.S. will be canceled from this afternoon on (the airlines have not yet announced)

What the FAA is doing

Lifted the nationwide stop at 10:15 a.m. Airlines are working on rebooking canceled and delayed flights
Expecting airborne holding nationwide, it extended the time before filed flight plans are canceled to 240 minutes (around 6:20 a.m.)
Investigating the cause (the Transportation Secretary: "FAA engineers are looking into it")

[Ground stop at U.S. airports (4:03 p.m., November 14)]
The ground stop at all U.S. airports (5:54 a.m. to 10:15 a.m. JST on November 14, caused by an air traffic control communications failure) has been lifted, but cancellations and delays are expected to continue for several days.
