Here’s what to know about the outages.
A global technology outage, attributed to a glitch in a software update issued by the cybersecurity firm CrowdStrike, wreaked havoc on airlines, health care systems, banks and scores of other businesses and services around the world on Friday. The disruption, which reached what some experts called “historic” proportions, was a stunning example of the global economy’s fragile dependence on certain software, and the cascading effect it can have when things go wrong.
The software update resulted in crashes of machines running the Microsoft Windows operating system. George Kurtz, CrowdStrike’s chief executive, said it was not a security incident or a cyberattack. He said a fix had been sent out but warned that it could take some time to be put in place.
“We’re deeply sorry for the impact that we’ve caused,” Mr. Kurtz said on NBC’s “Today” show.
CrowdStrike’s software is used by myriad industries around the world. Disruptions persisted throughout Friday as businesses manually updated their systems and airlines struggled to get crews and planes to where they were needed.
Flights in the United States started taking off again by late morning, and crucial services, including emergency systems, were up and running. But progress was uneven as major companies, including banks and retailers, as well as health care systems struggled to get back online. Microsoft’s chief executive, Satya Nadella, said in a post on X that the company was working with CrowdStrike to help customers recover.
Here’s how the spillover effects were felt all over the world:
Flights disrupted: U.S. airlines began restoring service on Friday after at least five of them — Allegiant Air, American, Delta, Spirit and United — had grounded all flights for a time, according to the Federal Aviation Administration. Travelers did not see immediate relief, however, even as flights took off, because of cascading delays at airports. By Friday afternoon, more than 2,000 flights across the country had been canceled, according to FlightAware, compared with about 900 on Thursday. But it was far from the country’s worst travel day of the year: Bad weather forced U.S. airlines to scrap more than 3,100 flights on Jan. 15.
Global reach: The issues were also felt at other airports around the world, including in Hong Kong; Sydney, Australia; Berlin; and Amsterdam. In Britain, check-in machines stopped working. The United Parcel Service and FedEx both reported disruptions, which could delay deliveries in the United States and Europe. Customers with TD Bank, one of the biggest banks in the United States, reported issues with accessing their online accounts, and several state and municipal court systems closed for the day because of the outage.
Emergency care: The outage destabilized health care systems across the globe, and hospitals canceled noncritical surgeries on Friday. Emergency response systems in the United States were also affected, and 911 lines were down in multiple states, the U.S. Emergency Alert System said on social media. Most, if not all, of the 911 problems appeared to have been resolved by midmorning. Kaiser Permanente, a medical system that provides care to 12.6 million members in the United States, said that all of its hospitals were affected, and it activated backup systems to keep caring for patients.
Federal response: President Biden was briefed on the CrowdStrike outage, White House officials said. Administration officials were “in touch with CrowdStrike and impacted entities” and “engaged across the interagency to get sector-by-sector updates.”
Largely unaffected systems: Some basic services, including major grocery store chains and public transit systems, appeared largely unaffected by the outages, at least in the United States. Amazon Web Services and Google Cloud, two of the major cloud-computing platforms alongside Microsoft Azure, said that by and large, their services were operating normally.

Terminal 3 in San Francisco International Airport had long lines of weary travelers, but they seemed to be taking it all in stride for the most part. Some had been waiting since yesterday for their flights. Plenty of snacks and water were available to the passengers, some of whom resorted to finding a spot on the carpet to get a few minutes of shut eye.

U.S. airlines must offer some stranded travelers compensation.
The Transportation Department said on Friday that U.S.-based airlines must provide affected passengers compensation for flight disruptions set off by the global software outage that had roiled air travel, spurring thousands of delays and cancellations worldwide and in some instances, stranding travelers abroad.
The move is a significant reversal from how airlines were treating the situation earlier in the day, as something inherently outside their control for which their only obligation to passengers was free rebooking of their flights and nothing further. Delta Air Lines and United Airlines had both previously told travelers that they would not foot the bill for lodging.
But that changed when Transportation Secretary Pete Buttigieg said in a televised statement on Friday afternoon that airlines needed to treat the software outage just as they would a mechanical or technical failure, situations that were firmly within an airline’s control where airlines generally covered costs for food, lodging and transport.
“We have reminded the airlines of their responsibilities to take care of passengers if they experience major delays,” Mr. Buttigieg said.
What airlines are now required to provide depends on the severity of the inconvenience a traveler experiences. Any compensation would kick in only after three hours had elapsed. Passengers with overnight delays or cancellations can expect complimentary ground transportation and accommodation, and meal vouchers if they’ve waited three hours or more.
Many travelers on Friday reported waiting far longer than three hours for rescheduled flights, and said they had been dealing with an organizational nightmare: glitching airline apps, interminable phone waits and conflicting information from airlines that they’d be on the hook for costs.
On Friday, passengers booked on a United Airlines flight from Narita Airport in Japan to Newark Airport were told after a roughly four-hour delay that their flight had been canceled. A gate agent then informed them that the airline would not subsidize hotels or transportation from the airport and that they were on their own. Some were told the earliest they could be on a rescheduled flight was on Monday. By 2 a.m. on Saturday local time, at least 100 passengers were waiting outside the airport, hoping to find a ride elsewhere.
A United Airlines spokesman confirmed on Friday afternoon that it was treating the delays as controllable. Representatives for Delta Air Lines and American Airlines have not directly commented on the matter.

At CrowdStrike, engineers described an atmosphere of confusion as the company struggled to contain the damage on Friday.
Executives urged employees not to speculate on why the mistake had happened and directed them to instead focus on a fix for the millions of computers that were affected, said two engineers who spoke on the condition of anonymity because they were not authorized to speak publicly. Computers not connected to the cloud required a physical fix to the error introduced by CrowdStrike, they said, which could take weeks.

Many hospitals cancel nonessential surgeries.
Hospitals and health care providers across the United States told patients on Friday morning that a global technology outage had downed some information technology systems, resulting in canceled surgeries and other procedures, though the hospitals emphasized that emergency departments remained open.
Some major hospital systems were affected, including the Kaiser Permanente medical system, which runs dozens of hospitals and hundreds of medical offices in the western United States and elsewhere in the country. Kaiser Permanente activated its national command center around 7:30 a.m. Eastern to address “widespread” effects of the outage on its system, said Steve Shivinsky, a spokesman for the health provider.
The outage was affecting “all of our hospitals,” said Mr. Shivinsky, who called the situation “unprecedented.”
Banner Health, a large system based in Phoenix that operates hospitals and health care centers in six states, said that it closed clinics, urgent care centers and other outpatient facilities on Friday morning, but that hospitals would remain open for inpatient care and medical emergencies.
Mass General Brigham hospital system, which operates 15 hospitals across New England, had canceled all nonurgent procedures, surgeries and visits, hospital officials said on Friday morning.
The problems stemmed in many places from hospitals losing access to patient-record systems.
When Epic Systems, a widely used patient record-management application, went down on Thursday night at hospitals in the Providence Health system, “we knew we had a catastrophe on our hands,” said B.J. Moore, the chief information officer.
With 52 hospitals in seven states and 1,000 clinics, Providence Health, based in Renton, Wash., is one of the largest health systems in the country, Mr. Moore said. Patient records continued to be accessible on phones and iPads, he said, but enough applications, including ones used in surgeries, were down that many nonemergency procedures had to be canceled on Friday.
All 15,000 servers that run constantly were down. And thousands of computers — some 40,000 out of 150,000 throughout the system — “blue-screened” or had other issues starting on Thursday night.
Mr. Moore estimated that more than 1,000 people across Providence Health, including some in India, were working to fix the outage, and that fully restoring operations could take weeks. “This is worse than a cyberattack,” he said, adding that in a cyberattack, only Providence would be affected, not the other companies it relies on, including labs that process blood work and medical suppliers.
Several other hospitals and hospital networks also reported disruptions, which occurred after a software update issued by CrowdStrike, a cybersecurity firm, led systems to crash.
The two largest providers of dialysis in the United States, DaVita and Fresenius Medical Care, said in statements that the outage did not affect patients.
Despite major disruptions to commercial air travel, the transport of donated organs was also largely unaffected, according to several sources in the organ transplantation world.
Most organs are not transported on commercial flights, said Anne Paschke, a spokeswoman for the United Network for Organ Sharing, or UNOS, the organization that manages the U.S. organ transplantation system under contract with the federal government. The organs are instead transported on chartered flights or hospital helicopters, or, when traveling shorter distances, they are driven to their destination.
The system that matches organs with recipients did go down, however. It was out for about an hour in the early hours of Friday, but was “back online” before 2:30 a.m., according to a statement from UNOS.
For many, the issues at hospitals came as a surprise.
Ian Philp, who lives in Brooklyn, N.Y., said his family arrived at Maimonides Medical Center on Friday morning, only to learn that his son’s tonsil and adenoid operation had been called off. The family had not received a call about the cancellation, Mr. Philp said, nor could they reschedule: The scheduling system was down.
His son, who is 7, was relieved, Mr. Philp said. “He gets a free day, but he was sad he was not going to have an all-ice-cream diet for a week.”
Citing the “global IT outage,” Maimonides Medical Center said on social media that it had canceled some nonessential procedures, but that “we remain open and patients continue to receive safe, high-quality care.”

How to fix a Windows computer impacted by the outage.
An outage that crippled businesses around the world turned many Microsoft computers into bricks overnight.
That means a lot of people are seeing the blue screen of death as computers continually try to reboot. The issues stemmed from a faulty software update delivered to Microsoft devices and servers from CrowdStrike, a cybersecurity company that mainly works to help protect bigger companies from attacks.
On Friday, CrowdStrike said it had issued a software update fix that should repair the computers, and it posted instructions for manually fixing the problem. Customers can also call the company. But cybersecurity experts said the process might still be complicated.
Here’s what to do if you’re affected.
Why is your computer crashing?
If your computer is bricked, you’re not alone. The problem, cybersecurity experts say, is with a bug in an overnight update caused by a bad file, which essentially sends the computers into an endless loop of reboots. That means the fix that CrowdStrike sent may not be able to repair your systems from afar.
About 300 companies on the Fortune 500 list are CrowdStrike customers, and it is the second-largest independent cybersecurity firm in the United States. If you work for a big company that is affected, your I.T. department will most likely need to be involved.
Adam Harrison, a managing director at FTI Consulting, which works with companies on their cybersecurity strategies, said smaller businesses were “less likely” to be using these kinds of security tools, although he added that many small businesses relied on vendors or suppliers who did.
So what should you do?
The truth is you probably can’t do all that much. Cybersecurity experts are saying that if a computer has entered a doomloop, it will most likely take an expert to fix it.
If you do happen to be tech savvy, CrowdStrike has posted instructions advising customers to put computers into a recovery mode. Then, you would need to delete the file that is causing the problem.
But that might be more complicated than you’d expect, cybersecurity experts say. For example, businesses may be operating hundreds or thousands of computers, which would increase the work required to bring its systems back online, said Mr. Harrison. Or, if you work at a retail store, the self-checkout kiosks frequently don’t have mouses or keyboards — and there most likely isn’t an I.T. specialist on site to help.
“There’s lots of complexity in solving this problem,” he said.
“This is millions of computers around the world,” said Mikko Hypponen, a security expert and chief research officer at WithSecure, a cybersecurity company. “Many of them are at home because of remote work. It’s going to take a long while, several days if not weeks, to fix them all if you have to go and physically touch every machine.”
Can CrowdStrike fix the issue remotely?
Not necessarily. CrowdStrike has tweaked the faulty update already. That means computers that did not already download the software won’t crash.
But machines that are already affected by the issue are stuck in a loop where they keep rebooting, making it harder to update them from afar. It is possible that CrowdStrike or someone else will come up with a way to automate the process of fixing the problem, which could make it easier for you or your employer to address the issue.
George Kurtz, the chief executive of CrowdStrike, said in an interview with the “Today” show that the update had been able to break through to some computers while they were rebooting, allowing them to receive the fix automatically. But many computers remain offline, and will require a manual fix.
What are Microsoft and CrowdStrike saying about the outage?
In a post on X, Satya Nadella, the chief executive of Microsoft, said, “We are aware of this issue and are working closely with CrowdStrike and across the industry to provide customers technical guidance and support to safely bring their systems back online.”
In a separate statement, Microsoft said to contact CrowdStrike. CrowdStrike advised customers who communicated through official channels.
“We understand the gravity of the situation and are deeply sorry for the inconvenience and disruption,” Mr. Kurtz said in a statement. “We are working with all impacted customers to ensure that systems are back up and they can deliver the services their customers are counting on.”

Courts close nationwide, and Harvey Weinstein’s case is delayed.
Court systems across the country were severely affected by the global outage, with some open only for emergencies and others closing their doors altogether.
In New York City, one particularly notable case was affected: A hearing in the sex crimes case of Harvey Weinstein, the disgraced Hollywood mogul, was delayed nearly two hours.
Judge Curtis Farber noted that Mr. Weinstein had been transported to the courthouse from the Rikers Island jail complex on time, but that the hearing was pushed back because of “disruption to the computer systems both in the courts and corrections.”
Some court appointments elsewhere were not happening at all. In Philadelphia, city courts were closed, and the entire Maryland judiciary system said it was open only for “emergency matters.” In Montgomery County, Md., some couples were milling around the courthouse hoping to get their marriage licenses, but they were eventually forced to delay their happily-ever-after at least for a while.
The Los Angeles Superior Court system, one of the largest in the country, was experiencing major connectivity issues. Court matters in which people were to appear remotely would be rescheduled, the court said.
Elsewhere in California, several courthouses — including in San Diego, Orange County, Alameda and Santa Clara — were open but experiencing delays. San Francisco’s courthouses were not affected, said a spokeswoman, Ann Donlan.

Why a security update to Microsoft devices disrupted the economy.
The global technology outage has put a spotlight on how Microsoft, the second-most valuable publicly traded company, is a major provider of software and cloud services for businesses and governments globally.
The tech behemoth, based in Redmond, Wa., has a $3.25 trillion market capitalization, more than the economic output of the United Kingdom, France or Mexico measured in gross domestic product.
Its cloud business, Azure, is a market leader and comprises giant computer server farms around the world that host the data of thousands of corporations and governments. It manufactures computers, and its Windows operating system software is widely used.
That scope makes an outage like the one on Friday painful.
In a statement posted to X, Microsoft’s chief executive, Satya Nadella, said that CrowdStrike, a cybersecurity firm, had released the update that affected I.T. systems.
“We are aware of this issue and are working closely with CrowdStrike and across the industry to provide customers technical guidance and support to safely bring their systems back online,” he said.
Microsoft’s ubiquity as a vendor for government agencies was raised during a hearing on a security breach that affected the tech giant last month. Lawmakers said the company provided an estimated 85 percent of the federal government’s productivity software with tools like Office and Excel. Microsoft is also one of the top cloud providers for the government, including for the Department of Defense.
“Microsoft is one of the federal government’s most important technology and security partners, but we cannot allow the importance of that relationship enable complacency or interfere with our oversight,” Representative Bennie Thompson, Democrat of Mississippi, said in the hearing, held by the Homeland Security committee.
Consumer interest and security groups say the widespread tech failure shows the danger of the company’s expansive grip on commercial and public sector markets.
“Today’s massive I.T. outage — potentially the biggest in history — is a clear demonstration of the dangerous and growing levels of concentration in our critical technology systems,” said Max von Thun, a director at the Open Markets Institute, a public advocacy group focused on antitrust law and policy.

Some Republican delegates find their Milwaukee stays have been extended.
Some delegates at the Republican National Convention found themselves stuck at Milwaukee Mitchell International Airport, running into delays and cancellations resulting from the global technology outage as they tried to head home.
Michael Holderness, a delegate from Sarasota, Fla., was considering driving 20 hours rather than being stuck at the airport. He recalled spending two days in December 2022 in Nashville after Southwest Airlines experienced computer problems. This time, he said, he did not want to wait for another flight after spending four days on the convention floor.
“I am trying to rent a car right now,” Mr. Holderness, 53, said. Aware that the flight problems might lead to a scramble for car rentals, he added, “I’ll rent a U-Haul if I have to.”
Rob Wilkes, 36, a U.S. Coast Guard member and a delegate trying to return to New Orleans, said he and two colleagues were thinking about renting a car to drive to Minneapolis to make their connecting flight, which still appeared to be on time.
“I’m just annoyed,” he said. “Waking up first thing in the morning hearing this is frustrating.”
John Regan, 88, a delegate from Huntington, Ind., was also trying to reach Minneapolis. After hearing about the outage, he arrived at the Milwaukee airport four hours early. He is scheduled to present his son, a dentist, with a fellowship at the Academy of General Dentistry on Saturday.
Mr. Regan felt “pretty confident” that he would be able to make it.
Instead of waiting around, Cheryl Meads, a 64-year-old from Hobe Sound, Fla., who attended the convention as part of a delegation from the Republican Governors Association, decided to stay an extra day in Milwaukee after her Delta Air Lines flight was canceled.
While the R.N.C. was taking place, she did not have much time to explore the city, she added. Now, she said, she could “actually have fun.”

911 systems were disrupted in at least 3 states.
Emergency call systems in at least three states were hit by the widespread CrowdStrike technology outage, although most major U.S. cities avoided problems overnight.
In Oregon, some 911 centers, hospitals, airports, and public safety and emergency management agencies had major effects, said Erin Zysett, a spokeswoman for the Oregon Department of Emergency Management.
“Our I.T. teams are working very fast to apply the fixes that CrowdStrike has provided, and those impacts are being mitigated quickly,” she said, adding that statewide alert systems and public safety incident tracking systems were mostly unaffected.
Emergency dispatchers in Portland, Ore., were forced to work without the help of crucial computer systems for several hours and had to work “manually,” Mila Mimica, a city spokeswoman, said in a statement. As of 6 a.m., however, the computer systems were back to working normally.
In Phoenix, the outage affected a computerized 911 dispatch center, Police Department officials said, but the city’s 911 centers were still operating. Dispatchers were still able to field calls, but they had to record communications on paper. The 911 call center was restored by about 6 a.m., the Phoenix police said.
In Alaska, problems began to emerge on Thursday night. Call centers across the state for many 911 emergency lines stopped working correctly because of “a nationwide technology-related outage,” the Alaska State Troopers said on social media.
Some dispatch centers lost use of their digital call systems and had to switch to analog phones or rely on other dispatch centers that were still functioning, said Austin McDaniel, the communications director for the Alaska Department of Public Safety. The problems were fully resolved around 4 a.m. local time, he added.
Emergency service outages have already affected services this year. In April, residents had problems calling 911 in parts of Nebraska and Texas, the entire state of South Dakota and Las Vegas. Last month, emergency agencies in Massachusetts scrambled to communicate with the public and directed them to alternative numbers after a firewall unintentionally prevented calls from getting through.
The outage on Friday led to a very busy 16 minutes for the San Francisco Fire Department. Between 2:34 a.m. and 2:50 a.m, 20 fire alarms in buildings around the city blared, prompting firefighters to respond to each one. The alarms were all false and apparently caused by the CrowdStrike outage, said Lt. Jonathan Baxter, a department spokesman.
Agencies in most large cities, however, said on Friday that their emergency communications systems were running as usual. In New York, the 911 system was functioning and emergency response was unaffected, a New York Police Department spokesman said. The authorities in Atlanta, Minneapolis, Indianapolis and Miami also reported that their 911 systems were unaffected.
The outages affected less urgent government operations in some areas of the country. The Department of Motor Vehicles offices in Georgia, Ohio and Indiana said that they had been disrupted or were expecting potential outages. In Hudson, a suburb about 40 minutes south of Cleveland, utility billing and phone systems were down. Hudson closed its City Hall for the day.

Flying today? What you need to know about the global tech outage.
While commercial air service was slowly recovering on Friday after a technology outage caused thousands of flights worldwide to be canceled or delayed, the ripple effect from the disruption left airports crowded with passengers and airlines working to get planes and crews back in position.
“These flights, they run so tightly, so back to back, that even after a root cause is addressed, you can still be feeling those impacts throughout the day,” said Pete Buttigieg, the transportation secretary, in an appearance on CNBC.
The outage was caused by a flawed update from the cybersecurity firm CrowdStrike, whose software is widely used around the world. At United Airlines, for example, the outage affected technology used to calculate aircraft weight, check in customers and operate call-center phone systems.
Throughout Friday, messages that travelers posted on social media showed flights grounded worldwide, some terminal monitors down and crowds of stranded passengers waiting at airport gates and customer service desks. At airports in India and South Korea, some passengers stood in long lines to obtain handwritten boarding passes.
Are flights still grounded?
Since the initial outage, service is slowly resuming, but the number of global delays and cancellations has continued to increase throughout the day.
Worldwide, around 110,000 commercial flights were scheduled on Friday, and around 5,117 of those flights, or 4.6 percent, have been canceled, according to Cirium, an aviation data company. In the United States, the number of cancellations stood at more than 2,300 — or about 9 percent of daily flights — as of Friday afternoon.
Fewer than half of the flights today in the United States left on time, the others departing with delays of a half-hour or longer, according to Cirium.
Delays at some airports in the United States were well beyond an hour, according to data from the Federal Aviation Administration. The average delays at Kennedy International Airport and Hartsfield-Jackson Atlanta International, the world’s busiest airport, were nearly three hours.
Which airlines are most affected?
In the United States, at least five carriers — Allegiant Air, American Airlines, Delta Air Lines, Spirit Airlines and United — temporarily grounded flights, according to the F.A.A.
As of about 4 p.m. Eastern, more than 830 Delta flights had been canceled, and more than 1,220 had been delayed. American was reporting more than 360 flights canceled and more than 1,040 delayed. More than 380 United flights had been canceled and more than 1,260 were delayed, according to FlightAware.
The Dutch airline KLM canceled around 41 percent of flights on Friday, according to FlightAware. It has begun to recover, but advises passengers to check their flight status online before traveling. “We urge passengers not to come to the airport if their flight is not departing or is severely delayed,” the airline said in a statement.
Why weren’t some airlines, like Southwest, affected?
Southwest, Alaska Airlines and JetBlue Airways barely scrapped any flights on Friday. A spokesperson for Southwest said, “The outage did not directly affect our operations,” but did not elaborate on why.
Alaska does not use CrowdStrike, and its operations were “mostly unimpacted,” said Tricia Bruckbauer, a spokeswoman for the airline.
Which airports have been hit the worst?
In the United States, Hartsfield-Jackson Atlanta appeared to have the most flights affected by the outage, with a total of more than 590 incoming and outgoing flights canceled and more than 780 flights delayed as of midafternoon on Friday, according to FlightAware.
Many other airports, including hubs in New York, Chicago and Charlotte, N.C., also appeared to experience significant disruption. J.F.K. advised passengers not to show up to the airport without confirming flight status.
The outage also affected major airports in Europe. Several airlines at Schiphol Airport in Amsterdam were unable to gain access to their check-in systems. The systems have since restarted, and the airport said it was working with airlines to “get all passengers to their destinations as quickly as possible.”
London’s busiest airports, Heathrow and Gatwick, said they were using contingency systems to get around the outage, but both were still reporting delays for almost half of their incoming and outgoing scheduled flights.
Hong Kong International Airport had to switch to manual check-in, but the airport reported that flight operations were not affected.
I’m flying today. What can I do?
Pack patience.
Delta, United, American, and Spirit have issued flight waivers allowing passengers to rebook without any additional fees. The terms and applicable airports vary. Generally, passengers are required to depart within a week.
Travelers can usually check itineraries through the airline’s website or app, but some travelers on Friday reported difficulties rebooking through the Delta and United apps.
You can also contact airline customer service by phone, though travelers posting on social media said that they had not been able to reach agents. But there are a few tricks you can try aside from the primary hotline: U.S. airlines have overseas customer service phone lines, easily found on the internet, and those agents can help too.
FlightAware can offer detailed data about delays and cancellations, and which airports are most affected, in real time.
What are my rights if my flight is delayed or canceled?
You may be entitled to certain compensation — such as airline-provided hotel or meal vouchers — detailed on the Transportation Department’s Airline Customer Service Dashboard.
The Transportation Department said the software outage is considered within airlines’ control and that airlines must follow through on their commitments to travelers, which for most United States-based carriers include complimentary ground transportation and accommodation for those affected by overnight delays and cancellations, as well as meal vouchers for waits exceeding three hours. Travelers should not expect to have this compensation offered to them, but are within their rights to ask the airlines for it.
“We have reminded the airlines of their responsibilities to take care of passengers if they experience major delays,” Mr. Buttigieg said in his CNBC appearance on Friday.
Passengers’ rights can differ for international flights. For example, in the European Union, cancellations or long delays may give you the right to a refund, a replacement flight and financial compensation. Passengers on flights delayed overnight may receive reimbursement for food, accommodations and ground transportation. (Travelers should hold on to any receipts for costs incurred.)
I have a cruise to catch. Will I get a refund if I miss the ship?
Cruise lines typically do not provide refunds, rebooking or any other concessions if flight disruptions cause travelers to miss their cruise departure, and the large companies are not making exceptions now.
But things look brighter for Carnival and Royal Caribbean passengers who booked their airfare through the cruise lines. Should they miss their departure, those travelers can expect benefits including coverage for flights, hotels and ground transportation to get them to the next port of call.
“Regrettably, air service disruptions — whether technological or weather — are beyond our company’s control,” said Chris Chiames, the chief communication officer for Carnival. “We always encourage our guests to purchase travel insurance, and today’s news is an important reminder of why.”
I have travel insurance. Am I covered?
Travel insurance companies are expecting an influx of claims, mostly for delays and missed connections, as a result of the outage.
One agency, InsureMyTrip, anticipated more than 1,600 of its customers could be affected by the outage, said Suzanne Morrow, the company’s chief executive. Policyholders may be entitled to coverage for their expenses related to delays, as well as coverage for any missed connecting flights, she said.
Any travelers hoping to file a travel insurance claim related to the outage should make sure to keep all their receipts or bills to show proof of purchase, as well as check their insurance plan or policy and file a claim right away.

Banks were hit with short-lived glitches, but trading in the U.S. began as expected.
Financial transactions around the world were affected by a short-lived tech outage on Friday, hampering operations as workers struggled to log into their corporate systems.
Employees at companies including JPMorgan Chase and Instinet, a brokerage firm owned by the Japanese bank Nomura, had trouble gaining access to their work stations, according to people with knowledge of the matter who spoke on condition of anonymity. That led to delays in some trades as the companies rushed to find workarounds, the people said. By midday in New York, trading seemed to be functioning normally.
Customers of TD Bank, the 10th largest in the United States, turned to social media to complain they could not access their online accounts. “Teams are working hard” to restore services, a bank spokeswoman said.
Earlier, the London Stock Exchange said that its RNS corporate news service was unable to publish, citing a “third-party global technical issue.” The exchange operator added that the matter was not affecting securities trading and other services.
Norway’s central bank said that it suffered disruptions when conducting a securities auction on Friday, with participants having been asked to submit bids by phone or email.
However, the disruptions proved relatively short lived. In Norway, the central bank later said that the system was operating normally. Other central banks, including the Bank of England and the European Central Bank, said they had not experienced any technical issues.
By midday many other institutions also said they were operating as normal, with only pockets of disruption still causing problems for a small number of firms. Financial markets opened as usual, with the New York Stock Exchange and Nasdaq both reporting their markets were working as normal.
The S&P 500 fell modestly, down 0.6 percent by the afternoon. The tech-heavy Nasdaq Composite dropped 0.7 percent. Airlines, which had grounded some planes because of technical difficulties, were mixed, with Southwest dropping 1.5 percent while United recovered from earlier losses to trade up almost 1 percent. International Airlines Group, which includes British Airways and Aer Lingus, ended the day in London 2.2 percent lower.
Insurance businesses W.R. Berkley and Travelers Companies each fell by more than 7 percent. Intel also suffered, down over 5 percent.
Still, the sharpest drop came from CrowdStrike itself, the cybersecurity company whose software update sparked the outages. The company’s shares fell by as much as 15.4 percent, before it too moderated to a loss of just over 10 percent.
Despite calm returning to trading, the news will add to nerves over the tech-driven stock rally, which has broken through historical norms, basing its thunderous rise on the enthusiasm around artificial intelligence.
Microsoft, one of the primary beneficiaries of A.I. fervor that was also wrapped up in the CrowdStrike outage, fell just 0.6 percent, but that move came having already tumbled over 5 percent from its high point this month. CrowdStrike had also already dropped 12.5 percent from its July peak through Thursday.
