Holiday travel privacy risks and how to stay safe
NEWYou can now listen to Fox News articles!
Holiday travel is stressful enough with crowded airports, expensive flights and last-minute itinerary changes. But there’s a hidden part of the travel industry most people don’t know about: your personal data is being harvested, packaged and sold every time you book a flight, reserve a hotel room or check a travel app.
Whether you’re traveling for a Christmas break or booking early for New Year’s, the companies you trust with your most sensitive details—full name, home address, passport info, travel dates and device data—are sharing and selling far more than you think.
And during the holiday rush, that data becomes a goldmine for scammers.
Let’s unpack how this works, which companies collect the most and what you can do before you travel to keep your personal information out of the wrong hands.

PROTECT YOUR DATA BEFORE HOLIDAY SHOPPING SCAMS STRIKE
Holiday travel brings more than stress because every booking and check-in quietly generates personal data you may not realize you are giving away. (iStock)
Why holiday travel puts your data at risk
The holiday season is the peak period for travel-related data collection. Airlines, hotels, booking platforms, loyalty programs and travel apps all experience massive traffic spikes—millions of Americans are searching for deals, comparing prices, checking gate changes and re-booking delayed flights.
Every one of those actions creates trackable data points, including:
- Email address
- Phone number
- Full name and DOB
- Address history
- Travel itineraries
- Passport or ID data
- Device fingerprint
- IP address and location
- Shopping habits and spending patterns.
You might assume this data stays with the airline or hotel. It doesn’t.
Most companies share it with advertisers, analytics firms, data brokers and dozens of unnamed “partners.” Some even use your data to profile you—how often you travel, how much you’ll likely spend and whether you’re a “high-value” target.
That information can easily leak into scammer databases, which is why holiday travelers suddenly see:
- Fake “your flight is canceled” texts
- Phishing emails that look identical to hotel confirmations
- Bogus baggage fee requests
- Fake TSA PreCheck renewal notices
- “Urgent re-verification required” messages.
Scammers rely on the fact that you’re stressed, rushing and expecting travel updates. And because they already have your personal data, their attacks are frighteningly convincing.

Examples of what major travel companies collect
Here are real-world examples of how holiday travel platforms collect and share your data:
1) Airlines (Delta, American, United, Southwest)
Major U.S. airlines collect not just your name, phone number and email, but also travel companions, payment details, geolocation data, device data and loyalty-program activity.
They share this with:
- “Marketing partners”
- Analytics platforms
- Third-party advertisers
- Data-enrichment firms.
Many of these partners, over time, become part of the data broker ecosystem.
2) Booking platforms (Expedia, Booking.com, Hotels.com)
Each booking platform details what it collects in its privacy policy. Oftentimes, these sites track:
- Search history
- Price views
- Device fingerprint
- Click behavior
- IP-based location
- Payment attempts—even abandoned carts.
This is used to build profiles that determine what deals you’re shown and how aggressively you’re targeted.
3) Hotel chains (Marriott, Hilton, IHG)
Marriott’s privacy policy and other privacy statements list over 60 categories of data it collects. Some chains were caught sharing guest data with:
- Ad networks
- Social media platforms
- Third-party “guest experience” tools
- Affiliate networks
- Data brokers for cross-device tracking.
Cybercriminals have been using the information of over 500 million Marriott guests, exposed during a four-year-long breach that started in 2014, to craft and execute travel-themed scams to this day.
4) Travel apps (Airbnb, Hopper, KAYAK, TripIt)
These are some of the most aggressive data collectors because they run nonstop on your phone. Many collect:
- Real-time location
- Contacts
- Clipboard data
- Behavioral analytics
- Device ID
- In-app browsing.
Some of these firms then “share information with partners for marketing enhancement,” which is typically code for data selling.
YOUR DISCARDED LUGGAGE TAGS ARE WORTH MONEY TO SCAMMERS

How scammers use your travel data
Once your information enters the ecosystem, scammers build travel-themed attacks designed to hit you at the worst possible time. Some common examples include:
- Fake airline notifications: (e.g., “Your flight has been canceled, click here to rebook”)
- Urgent hotel “payment failure” emails: Scammers use leaked address and booking data to send emails that look exactly like they’re from the Hilton or Marriott
- Fake baggage fees: (e.g., “Pay $24.90 to release your checked bag”)
- TSA and Global Entry renewal scams.
This isn’t guesswork. They already have your name, flight, hotel, location and travel dates—because the travel industry’s data partners sold or leaked them.
How to protect yourself before you travel
Here are my top steps to staying private this holiday season:
1) Check what data the travel companies already have
Hotels, airlines and booking sites all have data removal options—though they’re buried in their privacy settings.
2) Stop apps from tracking your location
Turn off location permissions for apps like:
- Hopper
- Airbnb
- Expedia
- HotelTonight.
Many track you even when not in use. Here’s how to do it for iPhone and Android:
On iPhone: Open Settings, tap Privacy & Security, then tap Location Services, scroll down to the app and tap each app, and set location access to “While Using the App” or “Never,” and turn off “Share My Location” if you don’t want them to see your exact spot.
On Android: Open Settings, tap Location, then choose App location permissions or App permissions, find the app and tap it, and change each one to “Allow only while using the app” or “Don’t allow” so they can’t track you in the background. (Settings may vary depending on your Android phone’s manufacturer.)
3) Remove your personal data from data broker sites
This is the most important step. Even if you stop airlines and hotels from collecting new data, your existing data is already circulating through dozens of data brokers, and that’s what scammers use to target travelers.
Data brokers hold:
- Your travel patterns
- Address history
- Email and phone details
- Income level
- Household info
- Your family members’ names.
You can manually request removal from hundreds of sites, but it takes months. That’s why I recommend a data removal service. While no service can guarantee the complete removal of your data from the internet, a data removal service is really a smart choice. They aren’t cheap, and neither is your privacy. These services do all the work for you by actively monitoring and systematically erasing your personal information from hundreds of websites. It’s what gives me peace of mind and has proven to be the most effective way to erase your personal data from the internet. By limiting the information available, you reduce the risk of scammers cross-referencing data from breaches with information they might find on the dark web, making it harder for them to target you.

4) Use an email alias for bookings
An alias email reduces the amount of spam and phishing attempts you’ll receive. By creating email aliases, you can also protect your information. These aliases forward messages to your primary address, making it easier to manage incoming communications and avoid data breaches.
For recommendations on private and secure email providers that offer alias addresses, visit Cyberguy.com
5) Avoid airport Wi-Fi for anything involving payments
Scammers often run fake hotspots. So, avoid airport public Wi-Fi when accessing financial information.

Kurt’s key takeaways
The holiday season is here, and many of us are getting ready to travel to see family and friends. As travel picks up, personal data collection and sharing also increases. Airlines, hotels and travel apps often share your information with unknown third parties, which scammers can use to target you during your trip. Before you pack your bags, take a few minutes to remove your personal data from online brokers. Doing this helps protect your identity and lets you travel with peace of mind.

One year in, Big Tech has out-maneuvered MAGA populists
Welcome to Regulator, a newsletter for Verge subscribers about the technology and the tech bros upending American politics and the Trump administration. If you’re not a subscriber yet, and you’re interested in Silicon Valley’s adventures in sausage-making, you should do so here! It’s Q1! Surely the corporate budget will allow for it.
Precisely one year ago, Steve Bannon, the powerful, populist MAGA podcaster, was thrilled at the sight of the Big Tech CEOs swarming around Donald Trump. In the days before his inauguration, the major players were visiting Mar-a-Lago, signing checks, even showing up to sit quietly behind him during his second inauguration. For years, Bannon told ABC’s Jonathan Karl in an interview, Big Tech had undermined Trump: Jeff Bezos’ Washington Post had reported on him critically, for instance, while Meta and Alphabet’s subsidiaries had purportedly silenced his online presence. Now, Bannon said, they were “supplicants” to Trump, who’d hired MAGA regulators ready to tear apart those companies at any given moment. “Most people in our movement look at this as President Trump broke the oligarchs,” he bragged.
Even smaller pivots from firm MAGA positions in favor of the tech industry, and the response from said base, are telling. Last November, Trump sparked outrage from the right by defending the existence of H1-B visas for high-skilled foreign tech workers, going so far as to say that US workers lacked “certain talents” that prevented Big Tech from hiring domestically. Although Trump ended up radically overhauling the immigration lottery system in a more nativist favor, the continued existence of the H1-B visa program itself sparked a massive rift within the MAGAsphere: how could Trump let in any foreign workers, much less imply that they were better than American workers? What sort of “America First” was that?
For decades, even as a businessman, Trump’s had one consistent organizational principle: people and factions must constantly fight each other for his attention and favor. It happened all the time during Trump’s first term, when New York financiers, the Republican establishment, the career officials, Trump’s children, and the proto-MAGA wing were all fighting each other inside the West Wing. But by the time Trump returned to the campaign trail in 2024, the New Yorkers were exhausted and went home, the Republican establishment had caved to Trump, and the career officials were all about to be purged. MAGA populism had won, and they believed, to paraphrase Trump, that they would win so much that they would become tired of winning. It’s not like the populists haven’t claimed territory in Trump’s second administration. The Department of Justice is conducting lawfare against Trump’s critics, the Department of Homeland Security has given ICE a broadly terrifying mandate, and the Department of Defense (sorry, War) kidnapped a foreign head of state for the LOLs.
But honestly, I would not have expected a year ago, as I watched the tech CEOs applaud Trump in the Rotunda, that these “supplicants” would eventually sway Trump to their ways. I’m not sure how the next year looks for internal drama coming out of the White House. I will say, however, that it is very, very telling that Bannon, who once bragged that there was a plan in place for Trump to run for an unconstitutional third term, is reportedly eyeing a presidential run himself.
Well, in the sense of the Senate being on a one-week recess, during which I will be following the drama of Coinbase derailing the CLARITY Act over interest rates, before the Senate Banking Committee reconvenes. To my great regret, I am not at Davos, where CEO Brian Armstrong is and where most of the negotiations seem to be happening. So if you are in some private Swiss meeting with other tech overlords and have some insight into whether there will be an actual market structure bill passed in the upcoming year, please email me at tina@theverge.com, or over Signal at tina_nguyen.19.

FDA clears first at-home brain device for depression
NEWYou can now listen to Fox News articles!
For the first time, Americans with depression will soon be able to use a prescription brain-stimulation device at home.
The approval comes from the U.S. Food and Drug Administration and marks a major shift in how mental health conditions may be treated. The newly approved device is called FL-100, and it comes from Flow Neuroscience.
It is designed for adults 18 and older with moderate to severe major depressive disorder. Clinicians can prescribe it as a stand-alone treatment or alongside antidepressants and therapy. This decision matters because depression affects more than 20 million adults in the U.S. Roughly one-third do not get enough relief from medication or stop taking it due to side effects.

SIMPLE DAILY HABIT MAY HELP EASE DEPRESSION MORE THAN MEDICATION, RESEARCHERS SAY
Flow Neuroscience has gotten approval from the U.S. Food and Drug Administration for its FL-100 prescription brain-stimulation device. (Flow Neuroscience)
How the Flow FL-100 works
The FL-100 uses transcranial direct current stimulation, often shortened to tDCS. This technology delivers a gentle electrical current to the prefrontal cortex, a region of the brain tied to mood regulation and stress response. In many people with depression, activity in this area is reduced. By stimulating it, the device aims to restore healthier brain signaling over time. The system looks like a lightweight headset and pairs with a mobile app. Patients use it at home for about 30 minutes per day while clinicians monitor progress remotely.
The clinical results behind the approval
The FDA based its decision on a randomized controlled trial that evaluated home use under remote supervision. Participants who received active stimulation showed meaningful improvement on clinician-rated and self-reported depression scales. After 10 weeks of treatment, patients experienced an average symptom improvement of 58% compared to a control group. Many users reported noticeable changes within the first three weeks. The study was published in the journal Nature Medicine, adding credibility to the findings. Side effects were generally mild and short-term. Reported issues included skin irritation, redness, headaches, and brief stinging sensations at the electrode sites.

A growing shift toward tech-based mental health care
Flow’s device has already been used by more than 55,000 people across Europe, the U.K., Switzerland and Hong Kong. In the U.K., it is prescribed within parts of the public health system. Company leaders say the U.S. approval opens the door for broader access to non-drug treatment options. The momentum is not isolated. In 2025, researchers at UCLA Health developed another experimental brain-stimulation approach, signaling rapid growth in this field. Together, these advances suggest that at-home neuromodulation may soon become a standard part of depression care rather than a fringe option.
When will the device be available
Flow expects the FL-100 to be available to U.S. patients in the second quarter of 2026. A prescription will be required, and the companion app will be available on iOS and Android. The company also plans to explore additional uses for its platform, including sleep disorders, addiction, and traumatic brain injury.

What to know before trying Flow
Flow is FDA approved for adults 18 and older with moderate to severe major depressive disorder, and it requires a prescription from a licensed healthcare provider. Doctors can recommend it on its own or alongside medication or therapy. The headset is non-invasive and designed for home use, but it is not meant for emergency situations or people considered treatment resistant. It also does not replace crisis care or immediate mental health support. Most users wear the headset for about 30 minutes per session. Mild tingling, warmth, skin irritation or headaches can happen, especially early on. These effects are usually short-lived and monitored by a clinician through the companion app.
Flow pairs with a mobile app that guides treatment and supports remote clinical oversight. Your provider sets the treatment plan, and the device follows prescribed settings to ensure safe use. Pricing and insurance coverage may vary once the device becomes available in the U.S. Some patients may access Flow through clinics, research programs, or as it becomes more widely adopted in routine depression care. The bottom line is simple. Flow adds another evidence-based option, not a cure and not a one-size-fits-all solution. For people who have struggled to find relief, having another clinically proven choice can matter a lot.
What this means to you
If you or someone you care about struggles with depression, this approval expands the range of real treatment options. It offers a non-drug path that can be used at home under medical guidance. For patients who have not responded well to medication or who experience unwanted side effects, this could provide another way forward. It also reflects a broader trend toward personalized, tech-enabled mental healthcare.

Kurt’s key takeaways
This FDA approval feels like a real turning point. For years, brain stimulation for depression stayed locked inside clinics. Now it can happen at home with a doctor still guiding the process. That matters for people who have tried medications, dealt with side effects or felt stuck with limited options. This device will not be the right answer for everyone, but it gives patients and doctors one more proven tool to work with. And for many people living with depression, having another option could make all the difference.
If a doctor could prescribe a brain-stimulation headset instead of another pill, would you be open to trying it? Let us know by writing to us at Cyberguy.com.
