• Elon Musk boosted a New Yorker profile questioning OpenAI CEO Sam Altman's trustworthiness on X.
• The article appeared on X feeds on Monday, the same day Musk and Altman's trial kicked off in Oakland.
• Musk's lawsuit claims Altman deceived him on OpenAI's mission as a nonprofit.

A New Yorker magazine investigation detailing concerns about Sam Altman's leadership resurfaced on X feeds on Monday, at the behest of the social media platform's billionaire owner.

A post from Ronan Farrow, an investigative reporter, linking to his New Yorker profile of the OpenAI CEO titled "Sam Altman May Control Our Future—Can He Be Trusted?" showed up on the X "For You" page for some users on Monday, three weeks after it was initially posted on April 6.

The post was labeled as "Boosted" and said, "This organic post was boosted by @elonmusk."

It's unclear how many people were served the post on Monday, but several Business Insider reporters saw it in their feeds.

The profile was boosted as a high-stakes trial between Musk and Altman kicked off in Oakland, California, on Monday. Altman made an unexpected appearance in court as jury selection began. Musk was not in attendance.

Musk sued Altman and OpenAI in 2024, alleging he was deceived when he cofounded the company in 2015 and invested tens of millions of dollars, only for it to abandon its mission as a public benefit nonprofit. The case could cost billions for OpenAI, which is preparing for an IPO.

Musk went after Altman directly on Monday in a critical post on X.

"Scam Altman and Greg Stockman stole a charity. Full stop," he wrote, referring to Altman and OpenAI's president, who is also named in the lawsuit.

OpenAI said Monday the lawsuit was "a baseless and jealous bid to derail a competitor."

X did not respond to a request for comment or questions about the "boosted" feature, including how it works and how it compares to an advertising post, which is typically labeled "Ad."

The New Yorker declined to comment.

• Maine Gov. Janet Mills vetoed a bill that would have paused new data center projects until late 2027.
• Mills cited her support for an existing project and said she wanted to study data center impacts.
• Lawmakers in at least 12 states have tried and failed to ban data centers as local resistance grows.

Another state-level effort to ban new data center development just failed, this time in Maine.

Maine Gov. Janet Mills on Friday vetoed a bill that would have put a pause on data centers in the state until late 2027. Mills said she supports a moratorium on data center projects but that the bill, which passed the state House and Senate his month, did not include an exemption for a project already underway.

"A moratorium is appropriate given the impacts of massive data centers in other states on the environment and on electricity rates," Mills said in a letter to the state legislature. "But the final version of this bill fails to allow for a specific project in the Town of Jay that enjoys strong local support from its host community and region."

A statement shared by her office said the $550 million data center redevelopment project was needed in Jay, where a paper mill closure in 2023 "eliminated hundreds of good-paying jobs and dealt a significant blow to the local economy."

The governor said she would have signed the bill had there been a carve-out for the project, which she said is expected to create over 800 construction jobs and at least 100 high-paying permanent jobs in addition to generating property tax revenue.

Mills, a Democrat who is running for US Senate in 2026, said she plans to issue an executive order to create a council to look at the impact of data centers in Maine.

"I believe it necessary and important to examine and plan for the potential impacts of large-scale data centers in Maine, as the use of artificial intelligence becomes more widespread," she said.

Lawmakers in at least 11 other states have also tried and failed to pass legislation that would temporarily ban new data center development, Business Insider previously reported.

The data center boom, fueled by Big Tech's AI ambitions, has sparked pockets of local resistance across the US amid concerns about energy consumption and impact on energy costs as well as the environment.

A Business Insider investigation found Maine had two data centers in the state as of last year.

• Prosecutors say Gannon Van Dyke used military secrets to make trades on Polymarket.
• Kalshi says he tried to open an account on its platform but was blocked.
• Van Dyke, a master sergeant at Fort Bragg, was indicted on multiple felonies.

The Army Special Forces soldier indicted on charges that he used military secrets to win over $400,000 in Polymarket trades was blocked from opening an account on rival prediction market platform, Kalshi.

Elisabeth Diana, head of communications for Kalshi, told Business Insider that Gannon Van Dyke did not make it past the verification and know-your-customer process but declined to provide more details. Reuters, citing an unnamed source, had earlier reported that Van Dyke tried but failed to gain access to Kalshi.

Van Dyke, a 38-year-old master sergeant assigned to Fort Bragg in North Carolina, was charged with wire fraud and other felonies for placing more than $33,000 in trades related to US action in Venezuela, prosecutors said.

The career soldier was involved in the planning and execution of Operation Absolute Resolve to capture Venezuelan President Nicolás Maduro and used classified information to make his bets, the indictment alleges.

Van Dyke is being prosecuted in New York, but made his first appearance in federal court in North Carolina on Friday. The court docket states that the government did not seek to detain him, and he was released on $250,000 bond.

He is represented by federal public defenders, who did not respond to a request for comment. He also did not respond to a call from Business Insider.

Polymarket did not immediately respond to an inquiry about the vetting Van Dyke underwent when he signed up for an account. The company said that it tipped off the feds to Van Dyke's trades.

In a statement on X, CEO Shayne Coplan said, "Noise aside, the reality is we work proactively with all relevant authorities on any suspicious activity on our marketplace. We flagged this, referred it, and cooperated throughout the process. This happens constantly behind the scenes, despite what many are led to believe."

Critics have raised alarms about the potential of insider trading on prediction markets and fretted about the possibility that the markets or the current events that fuel them could be manipulated for profit. Kalshi bans insider trading, and Polymarket bans trades based on confidential information.

Kalshi earlier this week said it suspended three political candidates for trading on their own elections as the platform moves to crack down on insider trading.

Asked about the Van Dyke case by reporters in the Oval Office on Thursday, President Donald Trump said he wasn't a big fan of prediction markets.

"The whole world, unfortunately, has become somewhat of a casino," Trump, who once owned several casinos, said. "I don't like it, conceptually, but it is what it is."

Michael Selig, chairman of the Commodity Futures Trading Commission, which regulates prediction markets, has defended the businesses, at one point calling them "valuable to society."

The commission filed a civil complaint against Van Dyke in federal court on Thursday.

• Meta and YouTube were found negligent in a landmark social media addiction trial.
• The case centered on a woman who said social media harmed her mental health from a young age.
• The case is viewed as a key test of how juries may see dozens of similar pending lawsuits.

Meta and Google were found negligent in a social media addiction trial in Los Angeles on Wednesday, potentially setting the stage for dozens of similar lawsuits that have been brought against Big Tech companies.

The case centered on a 20-year-old woman, identified as KGM, who said her use of social media from a young age was detrimental to her mental health and accused the companies of knowingly engineering their products to addict kids.

After nine days of deliberation, the jury found Meta, the parent company of Facebook and Instagram, and Google, which owns YouTube, negligent. In a 10-to-2 vote, the jury also ruled that the two companies knew their design was "dangerous" but failed to warn the plaintiffs.

The jury awarded the plaintiff $6 million. That's $3 million in compensatory damages and an additional $3 million in punitive damages.

The jury determined Meta was responsible for 70% of the harm, while YouTube was responsible for 30%. That means the total damages owed by Meta is $4.2 million, while YouTube owes $1.8 million.

The plaintiff's lead counsel, the Lanier Law Firm, called the verdict "a referendum" in a statement. "For years, social media companies have profited from targeting children while concealing their addictive and dangerous design features," the statement said.

Spokespeople for Meta and Google both said the companies disagreed with the verdicts and plan to appeal.

"Teen mental health is profoundly complex and cannot be linked to a single app," a Meta spokesperson said. "We will continue to defend ourselves vigorously as every case is different, and we remain confident in our record of protecting teens online."

"This case misunderstands YouTube, which is a responsibly built streaming platform, not a social media site," the Google spokesperson said.

The Los Angeles state court trial has been viewed as a bellwether, offering a key test of how juries may see similar personal injury lawsuits brought by over 2,000 individuals. Meta has said potential damages in certain cases could reach into the "high tens of billions of dollars."

TikTok and Snapchat were also defendants, but settled the lawsuit before the trial began.

Meta executives testified at the trial last month, including CEO Mark Zuckerberg and Head of Instagram Adam Mosseri, drawing large crowds of media and concerned parents, including some involved in other social media addiction lawsuits. YouTube's VP of engineering, Cristos Goodrow, also testified.

The companies have argued that plaintiffs' struggles are due to myriad reasons and can't necessarily be linked to social media.

During Meta's closing argument at the Los Angeles trial, Paul Schmidt, one of the company's attorneys, said the plaintiff needed to prove that if Instagram were taken away from KGM, her "life would be meaningfully different."

"The evidence has shown just the opposite," Schmidt said.

In January, Meta warned investors that its mounting legal battles related to youth safety could "significantly impact" its 2026 financial results. Attorneys for more than 100,000 individual arbitration claimants have "sent mass arbitration demands relating to 'social media addiction'" since late 2024, the company said in a 2026 10-K, specifically noting the case in Los Angeles, as well as a separate case in New Mexico.

The New Mexico case, which occurred at the same time as the Los Angeles trial, addressed different legal and technical issues.

On Tuesday, a jury in New Mexico ordered Meta to pay $375 million after a verdict came down in the state's lawsuit against the company about sexual exploitation.

Meta said it would appeal the case.

• Delays persist at TSA checkpoints across US airports due to the partial government shutdown.
• As of Monday morning, Hartsfield-Jackson Atlanta Airport is advising travelers to show up 4 hours early.
• Here's the latest on TSA delays, and how to check wait times before you travel.

If you're flying in the US, get ready to stand in line.

Airports across the US are continuing to see lengthy waits at security checkpoints as scores of TSA workers call out due to missed paychecks.

A partial government shutdown has left the Department of Homeland Security and its Transportation Security Administration unfunded and their agents unpaid at the height of the spring break travel season.

As many as 10% of all TSA agents called out on several days last week, DHS updates showed, with absence rates averaging as much as 20% in some airports. A DHS spokesperson told Business Insider that some airports, such as William P. Hobby Airport in Houston, had seen absence rates as high at 40.8%.

Security lines in affected airports are spiking unpredictably from day to day, and sometimes even from hour to hour.

"The current unpredictability is being driven by unpredictable staffing levels, basically, how many TSA officers are showing up for work on any given day," Sheldon H. Jacobson, the founder professor of engineering at the University of Illinois Urbana-Champaign and an expert on aviation security and airport security screening, told Business Insider.

"TSA officers have historically been cross-trained to do many different tasks, so the number that show up is the key factor," Jacobson said.

How long are the TSA delays?

Delays at TSA checkpoints across the US have been unpredictable, and some airports are changing how they're communicating with travelers.

As of Monday morning, Hartsfield-Jackson Atlanta International Airport, the world's busiest by passenger numbers, now displays the following message on its website: "Due to current federal conditions, passengers are advised to allow at least 4 hours or more for domestic and international screenings."

Atlanta has been among the worst-affected airports since the shutdown began, with over a third of TSA staff not showing up on some days.

The airport said there had been congestion at the international checkpoint as domestic travelers try to bypass long lines in the domestic terminal. The airport said domestic travelers should use the domestic checkpoints.

At Houston's George Bush Intercontinental Airport, lines stretched over three hours on Sunday evening. As of Monday morning, the average wait time is 28 minutes.

Lines at checkpoints at JFK, the New York area's biggest airport, are running at 45 minutes on Monday.

JFK said it has "deployed additional customer care staff into terminals to help manage queues, assist passengers, and keep people moving as efficiently as possible."

As of Monday, Newark Liberty International Airport displays a message on its website that says security wait times may be "significantly longer than normal."

"Please allow for significantly more time and check with your airline for the current status of your flight," the message says.

Separate from TSA issues, LaGuardia Airport was closed early Monday after a plane collided with a vehicle. It will remain closed until at least 2 p.m. ET.

Denver, home of the fourth-busiest airport in the US, is experiencing wait times of 45 minutes on Monday. Dallas-Fort Worth lines are at 46 minutes.

At Los Angeles International Airport, the nation's fifth-busiest travel hub, waits were listed as "0" minutes.

Some airports have so far avoided the hourslong lines. Business Insider's Taylor Rains flew out of Las Vegas last week and saw minimal TSA lines.

The maximum wait time at Philadelphia International Airport was listed as 30 minutes on Monday, although some terminals were quicker.

How to check TSA wait times

The unpredictable delays mean travelers should plan for long waits even if their airport hasn't yet experienced problems.

The easiest way to avoid the stress of missing your flight is to give yourself extra time in the airport. Many airports are advising travelers this week to arrive up to three hours before their flight, even for domestic flights.

Many airports, including major hubs like Atlanta, Houston, JFK, Newark, Philadelphia, Dallas-Fort Worth, and Denver, have been posting TSA wait times live on their websites.

These can also provide more specific insights. For example, DFW's website shows the wait times at each checkpoint.

You can also use the MyTSA mobile app. It provides estimated wait times in 15-minute intervals based on average checkpoint data. The app, however, will use historical data if the live data cannot be retrieved. The TSA also says it is not "actively" managing its sites during the partial shutdown, and so the app may not always be updated.

How long will the TSA delays persist?

Transportation Secretary Sean Duffy said airport delays could get worse.

"As we get into next week and they're about to miss another payment, this is going to look like child's play, what's happening right now," Duffy said on CNBC.

Some airports could be forced to close, both Duffy and Adam Stahl, the TSA's acting deputy administrator, said.

Airports like Denver and Seattle have asked the public for food, gift cards, and basic supplies to support TSA staff working without pay.

• Mark Cuban thinks humanoid robots will have a short lifespan.
• He said instead robots and spaces will be co-designed, and they won't necessarily look like humans.
• Tesla and OpenAI are among the companies investing in humanoid robots.

Mark Cuban believes in a future where humans live alongside robots, just not the ones you're probably picturing.

"Everybody's making this push for humanoid robots. I think they might have a 5-year lifespan, and then they'll fail miserably. Maybe 10," Cuban said Thursday on the live-streamed tech show TBPN.

Humanoid robots have plenty of fans, including Elon Musk, who has said he believes Tesla's Optimus could be the company's future. Business Insider reported in January that OpenAI had quietly built up a humanoid robotics lab last year.

But Cuban said he thinks co-designing spaces and robots would be better than simply making robots that mimic humans and fit into the world as it currently exists.

"I've heard people say, 'Well, a house is a house, you need a humanoid.' I think houses are going to be redesigned completely," he said.

For example, he said there could be robots that look like spiders or ants, capable of lifting and carrying things, while the house could be designed so that the pantry, refrigerator, and washing machine are hidden, with the robots primarily interacting with them, while the actual living space is used by people.

"The robots aren't going to be full-form humanoids. They're going to be whatever the optimal shape is," Cuban said. "You design the house to fit the robot, and you design the robot to fit the house."

He also pointed to Amazon's use of robots in its warehouses, noting they are not humanoids carrying boxes around. Amazon has said it has over 1 million robots that sort, lift, and carry packages. None of them looks like a human.

Still, major companies like Tesla and OpenAI, as well as smaller startups, continue to invest in developing humanoids. An executive at Agility Robotics, which has deployed its humanoids at Amazon and Toyota, told Business Insider its robots could step in to fill manufacturing roles that humans don't want.

"This re-shoring of manufacturing in the US is going to only occur through a combination of human employment and automation technology, like humans and robotics," he said.

Cuban did not respond to a request for comment from Business Insider.

• Companies like HP and IBM have signaled they're replacing jobs with AI.
• In February, CEO Jack Dorsey announced that Block was eliminating approximately 40% of staff.
• Klarna's workforce has halved in the last four years, and its CEO says it will shrink more.

Worries about AI one day replacing human workers have intensified in recent years — and as it turns out, that future has already arrived.

MIT released a study last year that found that AI can already replace 11.7% of the US labor market. The study utilized a labor simulation tool called the Iceberg Index, which models 151 million US workers and measures how AI overlaps with skills in each occupation.

As AI starts to replace human workers and companies invest heavily in the tech, companies have been increasingly open about the role AI adoption is playing in recent layoffs. However, while some companies have directly cited AI as a reason for workforce reductions, others have vacillated with their messaging, leaving ambiguity around the exact reasoning and whether AI is directly replacing workers.

Even as some companies replace human workers with AI, they might end up hiring more people in other roles because of it. A World Economic Forum survey found that 41% of companies globally are expected to reduce their workforces over the next five years because of AI. Meanwhile, tech jobs in big data, fintech, and AI are expected to double by 2030, the WEF said.

Here's a list of companies that are replacing — or signaling they may replace — humans with AI.

Amazon

Amazon CEO Andy Jassy has said that AI-driven efficiency gains would shrink the retail giant's workforce in the coming years — but in the company's two recent mass layoffs, Jassy said the cuts were about culture, not AI.

"Our ambition is to be the world's largest startup," Amazon executives wrote in two memos viewed by Business Insider in January. "That means doubling down on a culture of ownership, speed, and experimentation — which requires us to continue evolving how we're structured."

An Amazon spokesperson also previously reiterated to Business Insider that the cuts last October were not driven by AI.

When the October layoffs were announced, Amazon's senior vice president of people experience and technology wrote in a blog post that the move reflected a continued effort to run the company "like the world's largest startup." The SVP, Beth Galetti, also referenced a need to be leaner in the age of AI.

"This generation of AI is the most transformative technology we've seen since the internet, and it's enabling companies to innovate much faster than ever before," Galetti wrote in the post.

Atlassian

Atlassian announced cuts of 1,600 jobs in March, totaling about 10% of its global workforce. The move comes as the Australian-American software company says it is restructuring to focus on AI and enterprise growth.

In a filing with the US Securities and Exchange Commission, the company said the reduction was part of a broader effort to reposition the business for what CEO Mike Cannon-Brookes described as the "AI era."

"It would be disingenuous to pretend AI doesn't change the mix of skills we need or the number of roles required in certain areas. It does," Cannon-Brookes wrote in a message to employees.

On the "20VC" podcast in October last year, prior to the cuts, Cannon-Brookes said he planned to have more engineers at the company in five years.

"They will be more efficient, but technology creation is not output-bound," Cannon-Brookes said.

Block

In a post on X last month, billionaire and Block CEO Jack Dorsey said he was slashing nearly half of Block's workforce, cutting its over 10,000-person staff to under 6,000. The move came as he said business was strong and profits were growing, but a new way of working was emerging.

"We're already seeing that the intelligence tools we're creating and using, paired with smaller and flatter teams, are enabling a new way of working which fundamentally changes what it means to build and run a company," Dorsey said in his memo on X.

In the company's earnings call that followed the memo, Dorsey said that more companies will follow suit in using AI to drive efficiency gains. Block is already ahead of the trend that "all companies will eventually" adopt, the CEO said.

Fiverr

Micha Kaufman, the CEO and founder of Fiverr, said last September that the company was slashing roughly 30% of its workforce. The cut would affect about 250 team members, and the freelancing platform had 762 full-time employees as of 2024, according to an SEC filing.

The CEO said that the cuts were needed to help turn Fiverr into a leaner and faster "AI-first company."

Kaufman said in a staff memo last April that AI was "coming for your jobs," and in May, he told Business Insider that Fiverr would only hire people who know how to use AI.

"If you don't ensure that you sharpen your knives, you're going to be left behind. It's that simple," Kaufman said.

HP

HP said it's reducing the size of its corporate workforce as a result of AI initiatives. In an earnings report last November, the company said it plans to cut between 4,000 and 6,000 jobs by the end of 2028, estimating the changes would save around $1 billion.

HP's earnings presentation at the time said part of its strategy was to cut costs through "workforce reductions, platform simplification, programs consolidation, and productivity measures" and to increase customer satisfaction, innovation, and productivity with "artificial intelligence adoption and enablement."

IBM

Arvind Krishna, CEO of IBM, told The Wall Street Journal last year that it had replaced hundreds of human resources employees with AI.

More recently, the company announced last November that it would cut thousands of workers in the fourth quarter of 2025, affecting a "single-digit percentage of its global workforce." Its CEO, Arvind Krishna, said the company is shifting priorities to hire more people around AI and quantum. He also said the company plans to increase hiring among recent college graduates over the next year.

Krishna has also said AI adoption has led to the company hiring more employees in programming and sales.

In 2023, Krishna told Bloomberg that IBM had halted or slowed hiring for back-office roles, like in human resources, that could be replaced by AI.

"I could easily see 30% of that getting replaced by AI and automation over a five-year period," he told the outlet at the time.

Klarna

Klarna's CEO says its workforce has halved over the last four years and will shrink further in the coming years.

In an interview with Harry Stebbings on the "20 VC" podcast on Monday, Sebastian Siemiatkowski said there are about 3,000 employees at Klarna, and he expects the company's workforce to drop below 2,000 by 2030. The company had 7,000 employees in 2022, he said.

The CEO said the reduction is a result of layoffs and "natural attrition," which is when the company doesn't replace workers who leave.

Siemiatkowski said on Monday that "human connection" will be vital for the company, and jobs involved in that will not be replaced by AI.

"Those jobs will remain, but for the rest it's going to be definitely smaller," he said.

Klarna declined to comment further when contacted by Business Insider. A spokesperson previously said that its AI assistant handles the equivalent workload of 853 full-time agents, up from 700 at launch. The spokesperson said it was saving the company an estimated $58 million annually.

Salesforce

Salesforce cut fewer than 1,000 workers in February, including employees from marketing, product management, data analytics, and its Agentforce AI product.

In an episode of "The Logan Bartlett Show" released last August, Salesforce CEO Marc Benioff said the company was using AI agents in its customer support division to replace humans and help the company work through more sales leads.

"I was able to rebalance my head count on my support," he said in the interview. "I've reduced it from 9,000 heads to about 5,000 because I need less heads."

A Salesforce spokesperson told Business Insider previously that Benioff was referencing an organizational transformation that took place over several months to reshape its customer support function.

After deploying Agentforce, the company no longer needed to "actively backfill support engineer roles," the spokesperson said, adding that it successfully redeployed hundreds of employees into other areas of the company, like professional services, sales, and customer success.

Wisetech

Zubin Appoo, the CEO of Wisetech, said the logistics software maker is cutting 2,000 jobs, or 30% of its staff, because of AI-led efficiency.

In a conference call on February 25, Appoo said that AI enables greater productivity in less time and with fewer employees. The Sydney-based company employed about 7,000 people, according to an annual report released in October.

"I am prepared to say this clearly: the era of manually writing code as the core act of engineering is over," Appoo said. The technology is "unlocking levels of efficiency gains across WiseTech that were previously out of reach."

In some parts of the workforce, such as customer service, one in two workers will disappear, he added.

Correction: December 1, 2025 — The bullet points of this article have been updated to clarify Amazon's statements about how AI may affect its workforce.

• Airport security checkpoints in the US are under pressure due to the partial government shutdown.
• Many now-unpaid TSA agents are skipping work or even quitting, causing long lines and wait times.
• Here's the latest on TSA delays, and how to check wait times before you travel.

If there's anything that can bring Americans together to demand government action, it's long lines at airport security.

Those lines persisted at airports across the US this week as a partial government shutdown left the Department of Homeland Security and its Transportation Security Administration unfunded and their agents unpaid at the height of the spring break travel season.

Airports are now telling passengers to arrive up to three hours early to clear security in time for their flights.

The TSA on Sunday called on Congress to resolve the impasse over the immigration enforcement policies that have left the DHS unfunded for a month. The agency said hundreds of unpaid agents have quit.

"3+ hour TSA lines for travelers. 300+ TSA officers who have quit. A $0 paycheck for those continuing to serve. Enough is enough," the agency said in an X post on Saturday.

A group of airline CEOs also sent a letter to Congress on Saturday calling on Republicans and Democrats to figure it out. "Americans —who live in your districts and home states — are tired of long lines at airports, travel delays, and flight cancellations caused by shutdown after shutdown," the letter, which was signed by the CEOs of Delta, United, American, JetBlue, and others, says.

By early Tuesday morning, lengthy lines were still present at several airports, though they had calmed at some locations that had seen long lines over the weekend.

Hartsfield-Jackson Atlanta International Airport, the world's busiest by passenger numbers, had lines as long as 90 minutes at some domestic security checkpoints early on Tuesday morning, having seen waits of up to 2 hours over the weekend.

In a Monday X post, the airport encouraged travelers to allow extra time for screening and to arrive at least 3 hours before their flight. Many flights also faced lengthy delays or cancellations due to a major storm.

Lines at some checkpoints in the New York area's two biggest airports, JFK and Newark, were both around 30 minutes long early Tuesday.

At Dallas-Fort Worth, waits varied by checkpoint, ranging from over 20 minutes to as short as 2 minutes.

Austin-Bergstrom International was one of the worst-affected airports over the weekend, due in part to an influx of travelers for the SXSW festival.

The airport's social media channels are posting frequent updates about how busy TSA lines are, showing long lines in the terminal building on Tuesday morning.

While busy, Austin appeared to have calmed down compared to the end of last week and the weekend. Photos and videos shared by travelers over the weekend showed lines stretching from the terminal building into the parking lot.

To ensure passengers clear security in plenty of time, many airports are telling passengers to leave longer than usual to get through. Dallas-Fort Worth Airport told travelers to allow at least 2 hours for domestic flights, while Austin advised leaving 2.5 to 3 hours.

How to check wait times

The easiest way to avoid the stress of missing your flight is to arrive as early as you can. Many airports are advising travelers this week to arrive up to three hours before their flight.

To check TSA wait times, many airports, including major hubs like Atlanta, Houston, JFK, Newark, Philadelphia, Dallas-Fort Worth, and Denver, post them live on their websites.

These can also provide more specific insights. For example, DFW's website shows the wait times at each checkpoint.

While broadly reliable, some airport websites aren't always accurate. On Monday, Atlanta Airport said the feature was "currently unavailable due to a technical issue," although it was later fixed.

You can also use the MyTSA mobile app. It provides estimated wait times in 15-minute intervals based on average checkpoint data. The app, however, will use historical data if the live data cannot be retrieved. The TSA also says it is not "actively" managing its sites during the partial shutdown, and so the app may not always be updated.
