The Navy's new refueling drone completed its first test flight over the weekend. The MQ-25A Stingray is the Navy's first carrier-based unmanned aircraft. Right now, there are no unmanned refueling aircraft in service, but the Navy said the Stingray is expected to enter service in 2027.

Built by Boeing, the Stingray costs about $209 million per unit. The Navy invested about $16 billion in the system. After years of delays in the Stingray's development, this test flight gets the Navy closer to using it in military operations.

The Navy says the drone will be a valuable tool to extend the reach of crewed fighters and aircraft.

• Spiking jet fuel prices have left airlines looking for ways to recoup their extra costs.
• Many airlines have already increased ticket prices, and now some are bumping checked bag fees.
• Delta Air Lines said it will increase fees for first and second checked bags by $10 from Wednesday.

Travelers are feeling the pinch from the war in Iran.

Many airlines have already increased ticket prices and introduced fuel surcharges, but now there's a new target: checked bags.

Three major US airlines have increased baggage fees in recent days as soaring jet fuel prices have left them scrambling to offset skyrocketing costs.

The US and Israel's war on Iran has caused supply chain disruptions, leading to a surge in jet fuel prices, which has tightened margins for airlines.

Flight prices are rising as a result, and some airlines have already canceled — or are planning to cancel — flights due to the jet fuel shortages.

See which airlines have increased their fees for checked luggage:

Delta Air Lines

Delta Air Lines will increase fees for first and second checked bags by $10 from Wednesday, according to a statement shared with Business Insider.

For the third checked bag, fees will increase by $50. The changes apply to domestic and select short-haul international routes, and will not impact long-haul international flights or complimentary bag benefits, the airline said.

"These updates are part of Delta's ongoing review of pricing across its business and reflect the impact of evolving global conditions and industry dynamics," Delta said in the statement on Tuesday.

United Airlines

United Airlines said on Friday that it was raising the fees for first and second checked bags by $10. Like Delta, it said it will charge an extra $50 for third bags.

The airline said in a previously shared statement to Business Insider that this would apply to "customers traveling in the US, Mexico, and Canada and Latin America beginning with tickets purchased Friday, April 3."

JetBlue

JetBlue increased its checked baggage fees at the end of March.

The price of a first checked bag for a domestic flight has risen to $39 from $35 on non-peak days, and to $49 from $40 on peak travel days.

In a previous statement to Business Insider, the airline did not directly reference rising fuel prices as the reason for the fee increase, though it did note that its operating costs are rising.

"As we experience rising operating costs, we regularly evaluate how to manage those costs while keeping base fares competitive and continuing to invest in the experience our customers value," a spokesperson for JetBlue previously told Business Insider.

• The acting head of the TSA said more than 480 officers working without pay have quit during the shutdown.
• She said they can't be replaced fast enough to adequately staff airports for the World Cup in June.
• It could be another saga of long security lines due to understaffed TSA during a peak travel period.

Even if the partial government shutdown ends soon, the fallout at the Transportation Security Administration could spill into the summer's marquee event.

In a House testimony on Wednesday, acting TSA administrator Ha Nguyen McNeill said that so many officers have quit since their pay stopped in mid-February that the agency can't get replacements fast enough to adequately staff airports ahead of the World Cup in June.

She said TSA officers spend four to six months in training before working checkpoints, but the games — which will take place across 16 cities in the US, Canada, and Mexico — start in just 80 days.

"This is a dire situation," she said, adding that more than 480 officers have quit so far. "We are facing a potential perfect storm of severe staffing shortages and an influx of millions of passengers at our airports."

TSA agents haven't been paid for nearly six weeks, yet are deemed "essential" and expected to work during the shutdown, with back pay promised afterward. Their annual pay starts at around $40,000 and averages $60,000 to $75,000 a year with experience.

Still, many live paycheck to paycheck and can't afford to work unpaid for months at a time — quitting and finding another job or doing gig work is often their best option.

Mass TSA agent quits and callouts amid the shutdown, compounded by peak spring break travel, have already created hourslong security lines and stranded travelers. It's a preview of the chaos that could repeat when an estimated 6 million fans descend on potentially understaffed airports for the World Cup.

"If we see any spikes [in attrition], we're going to have to pivot and assess how we are going to staff the FIFA locations adequately," McNeill said.

Passengers traveling to the scheduled World Cup games in San Francisco and Kansas City, however, are likely safe from staffing chaos.

Both city airports use private security officers employed by contract companies instead of TSA, meaning their agents are being paid despite the shutdown.

It's not just the TSA sounding the alarm

Former Republican Sen. from Oklahoma, Markwayne Mullin — who was confirmed as the new head of the Department of Homeland Security on Monday after Kristi Noem's ousting in early March — said in a Senate hearing last week that the US is "behind" on World Cup preparations and the shutdown is making it worse.

"It'll take four months once funding comes in to start replacing those that we've lost for training before we can get them out in the field; we don't have four months with FIFA," he said. "How do we expect these people to stay on the job and work? We're losing institutional knowledge, we're losing people we've already trained."

The mass quits are exacerbating a problem that was already flagged last year.

A February 2025 report from the US Travel Association — long before the shutdown's impact could be factored in — warned that the TSA may not be efficient enough to handle surging travel volumes during the World Cup.

On its busiest days, the agency screened about 3 million passengers. During the games, the organization said that level of traffic would be the norm.

Lawmakers are still negotiating a funding deal to reopen DHS and end the partial shutdown.

• Noise-canceling headphones have been around for decades, but I never tried them — until now.
• I was so confused and freaked out by the sudden silence when I put in my new AirPods 4.
• I felt scared, like a caveman at a monster truck rally. Embarassing, really!

It's March of 2026, and I just bought my first pair of noise-cancelling headphones. I'm shocked, astounded, perturbed, and horrified: Is this how you people have been walking around all this time?!

Last week, after losing my right AirPods 3 earbud, I ordered a new pair of AirPods 4 with active noise cancellation. They're the first headphones I've ever worn with noise canceling.

Of course, noise-cancelling technology in headphones has been around since the 1980s, and became popular in big squishy over-the-ear Bose headphones in the 2000s. Noise canceling has been part of the AirPods Pro lineup since 2019. For some reason, I just ... never tried them.

My first experience with noise canceling

I set up my new AirPods over the weekend while waiting around in the parents' zone at a trampoline park. Because I didn't bother reading the instructions, which suggest pairing by holding the case next to your phone, I simply put the unpaired earbuds into my ears.

Immediately, everything went quiet. I looked around, confused. Did the loud trampoline park just turn off the upbeat pop music they were blasting? Why was everyone suddenly silent? Is there an emergency? Was someone hurt? Oh god, was my kid hurt?! I was panicked, scanning the other tables where adults idly sat looking at phones or tying preschoolers' shoes. No one else seemed to be concerned.

I took out the AirPods, and whoooosh — the music and din flooded back. My brain scrambled to make sense of the sensory experiences hitting it, slowly realizing that this was what noise-canceling does. I was like a caveman being shown a Bic lighter; fearful and confused. I was like the proverbial Victorian child who would pass out if you showed it the AI-generated video of anthropomorphic fruits on "Love Island."

This is incredibly embarrassing on one level because I am a professional technology journalist who generally tries to stay up to date and informed about interesting personal tech devices. The fact that I had never used noise-canceling headphones was an odd oversight.

I don't have good reasons for this, but I do have some weak excuses.

First and foremost, I'm cheap. And in my mind, headphones are something you shouldn't have to spend more than $20 on — up until the iPhone 12, Apple included a free set of corded headphones in the box with a new iPhone or iPod. I had a drawer overflowing with them! Headphones were just something that came into your life, like a cheap black umbrella — you didn't seek them out or intentionally buy them. Now, suddenly, I'm expected to drop a C-note on them?

When AirPods launched in 2016, I initially waved them off as overpriced and frivolous. It looked too easy to lose one. But eventually I gave in and, of course, realized that AirPods are incredibly convenient and great to use (I was right about them being easy to lose, however). Now, it's hard to imagine ever going back to wired headphones, no matter how much Gen Z makes it look cool.

My other main reason is that because I use headphones while walking down the street, riding the subway, or in other public situations, the idea of not being able to hear my surroundings felt like a safety issue. Sure, it might be nice on a plane, but it didn't make sense for my main headphone use.

Jury's still out on whether I like the noise canceling

As I've been playing around with the new noise-canceling headphones, I'm not sure how much I actually like them. Taking them in and out is disorienting, like coming up to the surface too fast while scuba diving (or, what I imagine that feels like).

I tried them at the gym, where they seemed useful, but at home, my husband (who has had noise-canceling headphones for a decade) was mildly frustrated when he tried to talk to me, not realizing I had them in. Understandable!

The AirPod 4s can turn active noise-canceling on and off if you rub the earbud's stem, but I haven't quite mastered this yet — I've tried and sort of fumbled around, turning my podcast on and off and knocking it out of my ear. I'll keep working at it.

I'm just glad to have finally joined the 21st century.

• 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."

• Western militaries need to study one Ukrainian operation in particular for drone warfare lessons.
• Officials say Operation Spiderweb, which struck dozens of Russian jets, offers key lessons.
• The US Army's drone course director told Business Insider it's "the one event that I teach to the students."

Western militaries are investing heavily in drone warfare after seeing their impact in Ukraine's fight against Russia's invasion. And while it isn't necessary to absorb every lesson, current and former military officials say one major operation is worth studying closely.

Maj. Rachel Martin, director of the US Army's Unmanned Advanced Lethality Course designed to accelerate training on small drone warfare, told Business Insider that the 2025 Operation Spiderweb is "the one event that I teach to the students."

Offensive potential

In the operation, Ukraine smuggled drones into Russia, drove them to positions close to Russian airfields, and launched them at strategically valuable aircraft. The Ukrainian drones hit 41 Russian warplanes and caused an estimated $7 billion in damage.

The strikes showed how arsenals of small, cheap drones can destroy high-value military assets far from the front — and how difficult they are to defend against.

The operation was complex and took roughly a year and a half of planning, but, Martin said, it showed "that a small amount of money could be spent to destroy something at the strategic level," in this case, bombers and other high-dollar aircraft.

It cost Russia billions of dollars when it "is already hurting financially from being in a prolonged war."

Seeing that kind of low-cost attack destroying assets that could take years to replace, she said, "was a big eye-opening experience for the world." It highlighted not only what was possible with attack drones on offense, but also critical vulnerabilities.

Defensive realizations

The Ukrainian operation sparked a realization in the West about the need for significantly more protection at air bases, especially those hosting essential mission tools, such as nuclear deterrence elements.

Lt. Gen. Andrew Gebara, the deputy chief of staff for strategic deterrence and nuclear integration for the US Air Force, said of the operation last year that "disruptive" technologies like the drones seen in the Ukraine war "will have big implications not just for our bomber force or our nuclear force but really any critical infrastructure."

"We have counter-drone capabilities at these bases. Do we need to continue to modernize? Do we need to accelerate?" he said. "Yeah, absolutely, all that."

The majority of the most strategic US air assets are based inside the continental US. American airpower also depends heavily on warplanes stationed at air bases around the world. Defending against drones has proven challenging at both home and abroad, as the Tower 22 disaster and a number of domestic incidents have highlighted.

European air bases have likewise grappled with the challenge of drones, making the lessons of Operation Spiderweb particularly poignant.

Retired Air Marshal Greg Bagwell, who spent 36 years in the British Royal Air Force and served as its director of joint warfare, said last month that Operation Spiderweb holds key lessons that NATO allies need to learn.

When it comes to modern drone warfare, the West has more to learn from operations like Spiderweb than from day-to-day front-line drone fighting, he said at the UK think tank Chatham House. The West doesn't necessarily need to engage in heavy quadcopter warfare at the front when it has artillery and substantial airpower.

"The lessons that we need to learn are more from Operation Spiderweb, where Ukraine employed these drones in a much more sophisticated way and really did start to take out some significant targets," Bagwell said. That operation had a high-level strategic effect on a stronger adversary for a comparatively lower cost. It's asymmetric warfare that the West can't ignore.

Picking up lessons from the war

The US is using drone warfare in ways beyond what Spiderweb demonstrated, drawing on other lessons from the war. In its war with Iran that started last month, it has used drones to attack Iranian targets, including the new one-way attack LUCAS drones.

It's also still employing traditional drone tactics, using platforms like the uncrewed strike and reconnaissance drone MQ-9 Reaper.

The Army's new drone course is just one of the many ways that it is advancing its drone warfare capabilities, along with other moves like plans to buy at least a million drones in the next two or so years. Allies across NATO are taking similar steps.

Martin said their power is undeniable, and the course itself was created because the Army could see that it was behind in small drone warfare and needed to fix that. But the US is not in the same existential fight that Ukraine is, nor is it facing the same weapons shortages.

Drones have kept Ukraine in the fight against Russia even as other weapons ran out. They haven't been decisive, though, indicating that deep stocks of traditional and advanced weaponry still matter.

The US Army course teaches soldiers that drones aren't always the right weapon.

Bagwell also cautioned against leaning too heavily on drones. He said that drones have been "hugely useful" for Ukraine, but "these have not won the war for either side."

He said that Ukraine has "had to adapt and fight the way they can only fight, and I applaud them for what they have done. But there is a question for us in the West as to whether that is the way we want to fight."

• 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.
