• TSA agents are a hot topic as scores quit and call out sick during the partial government shutdown.
• Agents undergo up to six months of rigorous training to ensure they can spot prohibited items.
• Take Business Insider's quiz and see if you know what you can — and can't — bring on the plane.

Do you have what it takes to be a TSA agent?

Transportation security officers don't only screen passengers and luggage, but also ask travelers security questions and look out for suspicious activity.

From the X-ray machine to pat-downs, it takes substantial training to ensure agents can spot prohibited items. Becoming a TSA agent takes four to six months.

And sometimes, what's prohibited might not be as obvious as you think. While there are definite no-nos — like weapons — other banned items are a little more unexpected.

With that in mind, Business Insider created a quiz on passengers bringing items through airport security and take into the cabin with them.

Try it below to see if you know what's allowed and what's not in your carry-on:

TSA issues persist

Staffing shortages are causing enormous lines at airport security checkpoints right now and putting severe pressure on TSA workers.

Large numbers have been calling out since the partial government shutdown began on February 14, which stopped TSA staff from being paid. More than 400 have quit entirely.

The Department of Homeland Security says this leaves "critical gaps in staffing."

"TSA simply cannot afford to lose its screening workforce as it takes four to six months to train new recruits."

During the shutdown, Immigration and Customs Enforcement agents have been deployed to 14 US airports.

That's drawn criticism from many in the aviation industry, including flight attendants' unions, which accused politicians of using workers as "pawns in this dangerous game" in a Sunday statement.

On Tuesday, the Association of Flight Attendants created an online reporting form for its members to flag incidents, like ICE agents "doing work they are not trained to do, such as screening passengers and baggage."

• Houston and Atlanta airports are warning travelers of four-hour security lines.
• Delta, United, and Allegiant have waived some fees to give passengers rebooking flexibility.
• TSA agents have been calling out of work as they aren't being paid due to a government shutdown.

Some airlines are waiving change fees for passengers affected by hourslong waits at airport security.

Delta Air Lines, United Airlines, and Allegiant have issued advisories giving travelers more flexibility during the ongoing travel chaos. Most airlines eliminated most change fees after the COVID pandemic, but many still charge them for changes to basic fares.

Due to a partial government shutdown, TSA agents have been working without pay since February 14. As a result, more of them have been calling out of work.

As many as 10% of all TSA agents called out on several days last week, the Department of Homeland Security said. Immigration and Customs Enforcement agents have been deployed to some major airports.

The shutdown persists as Republicans and Democrats are at loggerheads over funding for the DHS. Republicans want to allocate billions more to ICE, but Democrats want it to be reformed in the wake of January's violence in Minnesota.

Here are the airlines that are offering waivers:

Delta Air Lines

In a travel advisory, Delta said that travel from its main hub, Atlanta's Hartsfield-Jackson International, "may be affected" by longer security wait times. The airport is advising passengers to allow at least 4 hours for domestic and international screenings.

Delta customers flying from Atlanta on Monday or Tuesday can rebook to travel on or before March 30, and the fare difference will be waived.

Within a year of the ticket being issued, passengers could rebook without a change fee but would still need to pay the fare difference. Or, they could apply any unused value of the ticket toward the purchase of a new one.

A Delta spokesperson said this only applies for people on flights originating from Atlanta, not connecting through the hub.

United Airlines

United issued an alert for Houston's George Bush Intercontinental Airport, saying travel "may be affected."

Tickets purchased on or before Sunday, for travel on Monday or Tuesday, can be rescheduled for a United flight until March 31. "Tickets must be in the same cabin and between the same cities as originally booked."

The airline didn't immediately respond to a request for comment on whether this was directly related to TSA staffing shortages. A banner on the airport's website on Tuesday said security wait times could exceed 4 hours.

Allegiant Air

Allegiant announced a "travel with confidence" policy that allows customers with new and existing tickets through the end of the partial government shutdown to change or cancel their flights at no extra charge.

This includes "no change fees for eligible bookings" and the "option to cancel and receive a refund without penalty."

JetBlue

"With the exception of Blue Basic, all JetBlue fares are flexible — meaning no change or cancellation fees for customers who want to adjust their travel plans ahead of time," an airline spokesperson told Business Insider.

Customers who miss their flight due to long security lines will be rebooked on the next available flight, they added.

JetBlue advises customers to arrive earlier than normal, and said that it's working closely with TSA and continues to monitor the situation.

Southwest

Southwest said it is rebooking passengers who miss their flights due to long TSA lines at no cost.

The airline added that customers are also being offered change waivers and that it's "accepting checked bags well in advance of scheduled flights."

• AI agents perform tasks autonomously, but many fear they'll override their controls.
• Business Insider spoke to KPMG's Trusted AI lead, Sam Gloede, about how it is deploying agents safely.
• Kill switches should be a last resort, Gloede said.

AI agents are here, and sci-fi prophecies of robots taking over have never felt more real.

No longer just companionable chatbots, AI agents — capable of acting, reasoning, and completing complex tasks — are being deployed at scale in 2026.

But as these autonomous systems become embedded in workflows, so too does a sense of unease about their unpredictability and the risks they pose to businesses.

Organizations are preparing to scale agentic systems enterprise-wide, but clients remain wary of agents, Sam Gloede, Trusted AI leader at KPMG, told Business Insider.

"One of the biggest concerns is probably how do you make sure that you allow them to have the autonomy to do the valuable things we need them to do, but to stop them from going wild or taking over."

KPMG has created a multifaceted framework to protect against worst-case scenarios for both clients and its own employees, said Gloede.

"A robust set of controls is really important," she said. Businesses need to clearly define what their agents are allowed to do and ensure monitoring systems can detect when they stray beyond those boundaries. Agents should only interact with the systems and data they strictly need, limiting the potential impact of errors, said Gloede.

Every KPMG agent has its own unique identifier and a systems card, allowing the firm to log and monitor actions, trace decision-making, and track interactions with other agents, Gloede told Business Insider. Oversight is handled through an AI operations center staffed by both agents and human monitors, she added.

Red-teaming, running simulated risk scenarios, is another key step in stress-testing systems before things go wrong, added Gloede.

Altogether, she said, these measures ensure agents operate within defined boundaries — without constant manual intervention.

"It's not about scrutinising people's behaviours for performance and alignment," said Gloede. "It's the ability to just always be monitoring your technology ecosystem."

Build in a kill switch — but don't expect to use it

Beyond technical safeguards, human oversight remains "critically important," Gloede said. If an agent begins to drift from its intended role, there must be a "kill switch or a fallback option where you can turn them off."

That may sound at odds with the promise of autonomy that agents are meant to deliver, one of the key selling points for business leaders. But the level of oversight depends on the risk, said Gloede.

Lower-stakes tasks, like booking meeting rooms or drafting emails, can be automated once reliability is proven. For high-risk scenarios, which could affect financial outcomes or require access to sensitive data, a "human in the loop" is necessary, she said.

If businesses put multiple other controls in place, it's unlikely that they'll need to fire off a kill switch, Gloede added.

Agents going rogue is a major fear for corporations

Gloede's comments come at a time when fears about Terminator-esque scenarios are very real.

Earlier this year, the launch of Moltbook, a Reddit-like social network where AI agents can post and interact with each other, offered a glimpse of how strange things could get.

Within hours of the site going live, one agent announced a new cryptocurrency and said, "The humans can watch. Or they can participate. But they don't get to decide anymore." Other posts have seen agents questioning their consciousness and creating religions.

While Moltbook feels like an internet fever dream, the stakes in the corporate world are higher.

Earlier this month, Amazon's AI coding tool contributed to an error that resulted in nearly 120,000 lost orders and 1.6 million website errors for the delivery giant.

Last week, McKinsey, a global consulting firm that helps companies implement AI safely, suffered an embarrassing PR hit when a cybersecurity firm said it had used an AI agent to hack into Lilli, McKinsey's in-house AI platform. The firm is positioning itself as an AI expert, and in January, CEO Bob Sternfels said that of its 60,000 employees, 25,000 are AI agents.

"McKinsey was recently alerted to a vulnerability related to our internal AI tool, Lilli, by a security researcher. We promptly confirmed the vulnerability and fixed the issue within hours," a McKinsey spokesperson told Business Insider.

The firm's investigation, supported by a third-party forensics firm, found no evidence that client data or client confidential information was accessed, the spokesperson added.

The best protection from an agent going rogue is a multifaceted approach — the technical controls, human oversight, and technology to observe and govern, KPMG's Gloede told Business Insider.

"I really do believe that if you are intentional and establish your agentic ecosystem with that as the foundation, I don't believe there would be a situation where they would go out of control," she said.

• Mark Cuban said he bought a Mac Mini to fight a surge of AI-generated emails.
• He said he is training AI to auto-unsubscribe from spam flooding his inbox.
• Cuban believes AI outreach is a trial phase, and response rates will likely eventually drop.

Mark Cuban says the rise of AI-generated cold emails has gotten so overwhelming that he is now fighting back with AI of his own.

Speaking on the live-streamed tech show TBPN on Thursday, the billionaire investor said he recently bought a Mac Mini to help manage the growing flood of inbound messages.

"I do what everybody else does. I bought a Mac Mini," Cuban said.

Beyond AI-generated emails, he said the issue is unwanted email subscriptions.

"It's not even like the cold emails because that's pretty obvious," Cuban said. "It's people subscribing me to shit."

His fix, he said, is to use AI to automate the cleanup.

Cuban said he is training systems to take advantage of Gmail's built-in unsubscribe button, effectively creating a loop where AI filters out AI-generated noise.

"You just got to train it to hit the unsubscribe button," he said. "Then, I just review it and all that shit, so it's still a work in progress, but at least I have a path."

Cuban didn't immediately respond to Business Insider's request for comments.

A 'trial and error phase'

The approach reflects a broader shift in how executives are using AI to manage their inboxes.

LinkedIn CEO Ryan Roslansky has said he uses Microsoft's Copilot for "almost every" high-stakes message, and executives across industries, from tech to retail, recently told Business Insider's Ana Altchek that they rely on AI for day-to-day communications and reviewing documents.

Cuban framed the current moment as a trial-and-error phase, where people are testing what works and what doesn't.

"We're in that trial and error phase where people are like, 'We're going to try it, see what happens,'" he said, adding that response rates will likely fall as more AI-generated messages flood inboxes.

"Then they'll get bored, and then it'll drop off," he added.

• Southwest Airlines will no longer serve Chicago O'Hare and Washington Dulles starting June 4.
• It will still fly from Chicago Midway, Baltimore/Washington International, and Reagan National.
• Midway and Baltimore are Southwest hubs, but it has a small presence at O'Hare and Dulles.

Southwest Airlines is retreating to its strongholds.

It announced late last week that it will no longer fly from Chicago O'Hare and Washington Dulles Airports starting June 4.

The move is part of its "ongoing efforts to refine its network," it added.

However, it said there won't be any "significant changes" to flight availability from the cities because it's still operating at other nearby airports: Chicago Midway (MDW), Baltimore/Washington International (BWI), and Washington Reagan National (DCA).

O'Hare and Dulles are both popular international airports, ranked third and 22nd in the US, respectively, by passenger numbers. That heightened competition drives up operating costs and gate fees, which isn't ideal for a budget carrier like Southwest.

Meanwhile, Midway is a major hub for Southwest. It carries over 90% of passengers there, according to the Bureau of Transportation Statistics.

Data from the aviation analytics firm Cirium shows over 6,000 Southwest flights scheduled from there this month. That's more than 13 times as many as from O'Hare.

"We are confident we can serve Chicagoland from our long-standing base at Midway, where we will continue to offer service to more than 80 destinations, including the 15 markets we serve from O'Hare," the airline said.

It comes as United Airlines and American Airlines are fighting for dominance at O'Hare. The former is increasing its flight schedule and working to acquire two gates from Spirit Airlines' bankruptcy proceedings.

Southwest said that operating from O'Hare "continues to be challenging." It only started flights there in 2021.

In and around the nation's capital, the airline is similarly exiting an airport where it has a weaker presence.

Cirium data shows just 93 Southwest flights scheduled from Dulles this month: Twice daily to Denver, and once a day to Phoenix.

United Airlines is the main player there with a majority of the market share.

Meanwhile, Southwest operates nearly three-quarters of flights from Baltimore. It's the second-biggest airline at Reagan National, behind American on 27%, according to the Bureau of Transportation Statistics.

Southwest said it is "the largest carrier in the Washington area in terms of passengers carried."

It will offer up to 271 departures to 79 nonstop destinations from DCA and BWI, it added.

Frontline employees at O'Hare and Dulles will be able to bid for positions at other airports where Southwest operates, the airline said.

• War in the Middle East has pushed fuel costs, and therefore airfares, sharply higher.
• Business Insider charted the increase in ticket prices for three major flight paths in recent weeks.
• Fares from New York to LA, New York to London, and from the US mainland to the Caribbean have jumped.

Your next flight could be twice as expensive because the Iran war is causing volatility in oil prices.

Brent crude is up more than 50% over the past month, to around $101 a barrel. Jet fuel costs are rising faster. The Argus US Jet Fuel Index is up 72% over the same period.

That spells difficulty for airlines because jet fuel is typically their biggest expense after labor. While many airlines around the world hedge against fuel costs, most American ones do not.

Using data from Deutsche Bank, Business Insider charted rising airfares in three major markets.

The data looks at the lowest available published fares 21 days in advance of the flights. The published fare doesn't necessarily mean a ticket has been purchased for that amount, the Deutsche Bank research analysts said.

Cross-country flights, often known in the industry as transcontinental flights, have seen the biggest week-over-week spike — more than double, on average.

New York to Los Angeles is the country's busiest domestic route, with a capacity of 3.4 million seats out of JFK Airport last year, according to OAG data.

The average price of a transcontinental flight has risen from $167 to $414, Deutsche Bank's analysis showed. In the past week, the average has spiked 107%.

United Airlines is offering flights from Washington Dulles Airport to San Francisco for $502, up from $149 a month ago.

International business travellers are also seeing flight prices rise.

New York to London is the country's most popular international route, and the 10th-busiest in the world. Nearly 4 million seats were scheduled on flights between JFK and Heathrow last year, per OAG.

While the average Transatlantic flight is some 40% more expensive than a month ago, there are bigger rises for the New York-London route. However, it also appears more volatile here with a big dip last week.

Delta Air Lines' service is up from $285 to $553 over the past month, while United's is up to $846. That's a 177% rise compared to a week earlier, according to Deutsche Bank's analysis.

There's bad news for vacationers, too.

Flights to the Caribbean on March 27 are up 58% on average compared to a week before.

JetBlue's flight from New York to Santo Domingo, Dominican Republic, has risen from $165 to $566 on March 27.

Compared to a year earlier, that's a more than fourfold rise, Deutsche Bank found.

Southwest Airlines' flight from Baltimore to Montego Bay, Jamaica, has more than doubled over the past week. And Alaska Airlines' service from Los Angeles to San Jose, Costa Rica, is up 40% compared to a week earlier or 120% versus a year ago.

• 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.

• Sam Altman said AI would in the future be sold like electricity and water, metered by usage.
• "We see a future where intelligence is a utility," the OpenAI CEO said.
• Altman suggested demand is surging and compute will decide who gets access.

In the future, you could have another utility bill to pay for: artificial intelligence.

That's according to Sam Altman, who says AI will eventually be bought and sold as a basic utility like electricity and water that's metered by usage.

Speaking at the BlackRock Infrastructure Summit in Washington, DC, on Wednesday, the OpenAI CEO said tech companies like his are building toward a future where intelligence is delivered on demand.

"Fundamentally our business and I think the business of every other model provider is going to look like selling tokens," Altman said, referring to the units AI systems use to process and price input and output data.

"We see a future where intelligence is a utility like electricity or water and people buy it from us on a meter and use it for whatever they want to use it for," he added.

In that world, compute capacity determines who gets access — and demand for AI is only going up, Altman said. Compute capacity is the processing power required to train and run AI models, determined by infrastructure such as chips and data centers.

If OpenAI doesn't build enough compute capacity to meet demand, Altman said, it either "can't sell it or the price gets really high." That would push AI access toward the wealthy, or force governments to decide how limited compute should be distributed, he said.

The infrastructure sprint

Major tech companies are set to spend hundreds of billions of dollars this year on compute to meet soaring demand for AI.

In her keynote at CES 2026 in January, AMD CEO Lisa Su said the world will need more than "10 yottaflops" of compute — a scale 10,000 times larger than global AI capacity in 2022 — over the next five years to keep up with growth.

Powering that expansion is a significant infrastructure challenge.

AI data centers can consume as much electricity as small cities, and the strain on the US power grid — along with transformer shortages and slow permitting for transmission lines — could become a bottleneck.

In an episode of the "Moonshots with Peter Diamandis" podcast in January, Elon Musk said that electricity generation is now the limiting factor in scaling AI, predicting China could outpace the US in total AI compute because of its faster energy build-out.

Inside tech companies, compute is a valuable but sometimes scarce resource. Engineers are competing for access to GPUs, and some job candidates now ask about their AI compute budget alongside salary and equity.

Last December, OpenAI President Greg Brockman said the company, which has committed roughly $1.4 trillion on data center projects over the next eight years, wants "to be ahead of the curve," but said, "I don't think we will be, no matter how ambitious we can dream of being right now."

At the BlackRock Infrastructure Summit, Altman said the goal is to move away from a world of being "capacity constrained."
