Delta Air Lines rolls out AI for personalised airfare

Delta Air Lines is shifting the landscape of airfare by leveraging AI to personalise ticket prices. Moving beyond fixed fares, Delta aims to tailor prices closely to each traveller.

Instead of static prices, the system now analyses customer habits, booking history, and even the time of day to predict an individual’s potential willingness to pay. By the end of the current year, Delta aims to set 20% of its ticket prices using AI dynamically.

The goal represents a significant, sevenfold increase from just twelve months prior. Such a high-tech approach could result in more advantageous deals or elevated costs, depending on a passenger’s unique circumstances and shopping behaviour.

It is crucial to understand how this system operates, Delta’s motivations, and its implications for consumer finances. Traditional ticket pricing has long relied on ‘fare buckets,’ where customers are categorised based on their booking method and timing.

Delta’s new AI ticket pricing system fundamentally shifts away from these static rates. It analyses real-time information to calculate precisely what a specific customer will likely spend on a seat for any given flight.

Glen Hauenstein, Delta’s President, describes this as a complete re-engineering of pricing. He characterises AI as a ‘super analyst’ working continuously, 24/7, to identify the optimal price for every traveller, every time.

The airline has collaborated with Fetcherr, which provides the underlying technological infrastructure and supports other global airlines. Airlines do not adopt advanced, high-tech pricing systems to reduce revenue.

Delta reports that initial results from its AI-driven pricing indicate ‘amazingly favourable’ revenues. The airline believes AI will maximise profits by more accurately aligning fares with each passenger’s willingness to pay.

However, this is determined by a vast array of data inputs, ranging from individual booking history to prevailing market trends. Delta’s core strategy is straightforward: to offer a price available for a specific flight, at a particular time, to you, the individual consumer.

Consumers who have previously observed frequent fluctuations in airfare should now anticipate even greater volatility. Delta’s new system could present a different price to one person compared to another for the same seat, with the calculation performed in real-time by the AI.

Passengers might receive special offers or early discounts if the AI identifies a need to fill seats quickly. However, discerning whether one is securing a ‘fair’ deal becomes significantly more challenging. The displayed price is now a function of what the AI believes an individual will pay, rather than a universal rate applicable to all.

The shift has prompted concerns among some privacy advocates. They worry that such personalised pricing could disadvantage customers who lack the resources or time to search extensively for the most favourable deals.

Consequently, those less able to shop around may be charged the highest prices. Delta has been approached for comment, and a spokesperson stated: ‘There is no fare product Delta has ever used, is testing, or plans to use that targets customers with individualised offers based on personal information or otherwise.

Various market forces have driven the dynamic pricing model used in the global industry for decades, with new tech streamlining this process. Delta always complies with regulations around pricing and disclosures.’

Delta’s openness regarding this significant policy change has attracted considerable national attention. Other airlines are already trialling their AI fare systems, and industry experts widely anticipate that the rest of the sector will soon follow suit.

Nevertheless, privacy advocates and several lawmakers are vocalising strong objections. Critics contend that allowing AI to determine pricing behind the scenes is akin to airlines ‘hacking our brains’ to ascertain the maximum price a customer will accept, as described by Consumer Watchdog.

The legal ramifications of this approach are still unfolding. While price variation based on demand or timing is not novel, the use of AI for ultra-personalised pricing raises uncomfortable questions about potential discrimination and fairness, particularly given prior research suggesting that economically disadvantaged customers frequently receive less favourable deals.

Delta’s AI pricing system personalises every airfare, making each search and price specific to the user. Universal ticket prices are fading as AI analyses booking habits and market conditions. This technology can quickly offer special deals to fill seats or raise prices if demand is detected.

Conversely, the price can increase if the system senses a greater willingness to pay. Shopping around is now an absolute necessity. Utilising a VPN can help outsmart the system by masking location and IP address, which prevents airlines from tracking searches and adjusting prices based on geographic region.

Making quick decisions might result in savings, but procrastination could lead to a price increase. Privacy is paramount; the airline gains insights into a user’s habits with every search. A digital footprint directly influences fares. In essence, consumers now possess both increased power and greater responsibility.

Being astute, flexible, and constantly comparing before purchasing is vital. Delta’s transition to AI-driven ticket pricing significantly shifts how consumers purchase flight tickets.

While offering potential for enhanced flexibility and efficiency, it simultaneously raises substantial questions concerning fairness, privacy, and transparency.

Google seeks balance between user satisfaction and ecosystem health

At the Search Central Live Deep Dive 2025 event, Google’s Gary Illyes acknowledged that they are still calibrating how to weigh user needs, especially around AI-powered features, and the health of the broader web publishing community.

The company gathers internal survey data and tracks the adoption of external AI tools to assess satisfaction and guide product decisions.

While Google aims to enrich user experience with AI Overviews, critics warn these features may shrink organic traffic for publishers, as users often consume information without visiting source sites.

Illyes reaffirmed that Google does not intend disruption but is navigating a trade-off between serving users efficiently and maintaining a healthy content ecosystem.

Crypto hacks hit $3.1 billion by mid-2025

Cyberattacks and scams have already cost the crypto sector more than $3.1 billion in 2025, marking one of the most damaging years. Hacken’s mid-year report reveals that access control failures and social engineering tactics remain the primary culprits.

The most significant single incident occurred in Q1, when Bybit suffered a $1.5 billion breach, accounting for 83% of all Q1 losses. Access control weaknesses were responsible for around $1.83 billion, or 59% of funds lost across both DeFi and CeFi platforms.

Decentralised finance projects were hit particularly hard, with $300 million drained in Q2 alone. Smart contract vulnerabilities contributed to $263 million in losses, including a $223 million hit in the Cetus exploit.

Meanwhile, phishing scams reached new heights, with one incident in April involving a $330 million Bitcoin theft.

Q2 had fewer access breaches than Q1, but single leaks caused rapid, large-scale losses. Hacken’s report concludes that improved cybersecurity is essential for building trust and protecting innovation in the growing blockchain space.

Allianz breach affects most US customers

Allianz Life has confirmed a major cyber breach that exposed sensitive data from most of its 1.4 million customers in North America.

The attack was traced back to 16 July, when a threat actor accessed a third-party cloud system using social engineering tactics.

The cybersecurity breach affected a customer relationship management platform but did not compromise the company’s core network or policy systems.

Allianz Life acted swiftly by notifying the FBI and other regulators, including the attorney general’s office in Maine.

Those impacted are offered two years of credit monitoring and identity theft protection. The company has begun contacting affected individuals but declined to reveal the full number involved due to an ongoing investigation.

No other Allianz subsidiaries were affected by the breach. Allianz Life employs around 2,000 staff in the US and remains a key player within the global insurer’s North American operations.

UK enforces age checks to block harmful online content for children

The United Kingdom has introduced new age verification laws to prevent children from accessing harmful online content, marking a significant shift in digital child protection.

The measures, enforced by media regulator Ofcom, require websites and apps to implement strict age checks such as facial recognition and credit card verification.

Around 6,000 pornography websites have already agreed to the new regulations, which stem from the 2023 Online Safety Act. The rules also target content related to suicide, self-harm, eating disorders and online violence, instead of just focusing on pornography.

Companies failing to comply risk fines of up to £18 million or 10% of global revenue, and senior executives could face criminal charges if they ignore Ofcom’s directives.

Technology Secretary Peter Kyle described the move as a turning point, saying children will now experience a ‘different internet for the first time’.

Ofcom data shows that around 500,000 children aged eight to fourteen encountered online pornography in just one month, highlighting the urgency of the reforms. Campaigners, including the NSPCC, called the new rules a ‘milestone’, though they warned loopholes could remain.

The UK government is also exploring further restrictions, including a potential daily two-hour time limit on social media use for under-16s. Kyle has promised more announcements soon, as Britain moves to hold tech platforms accountable instead of leaving children exposed to harmful content online.

Agentic AI forces rethink of cloud infrastructure

Cybersecurity experts warn that reliance on traditional firewalls and legacy VPNs may pose greater risks than protection. These outdated tools often lack timely updates, making them prime entry points for cyber attackers exploiting AI-powered techniques.

Many businesses depend on ageing infrastructure, unaware that unpatched VPNs and web servers expose them to significant cybersecurity threats. Experts urge companies to abandon these legacy systems and modernise their defences with more adaptive, zero-trust models.

Meanwhile, OpenAI’s reported plans for a productivity suite challenge Microsoft’s dominance, promising simpler interfaces powered by generative AI. The shift could reshape daily workflows by integrating document creation directly with AI tools.

Agentic AI, which performs autonomous tasks without human oversight, also redefines enterprise IT demands. Experts believe traditional cloud tools cannot support such complex systems, prompting calls to rethink cloud strategies for more tailored, resilient platforms.

Women-only dating app Tea suffers catastrophic data leak

Tea, a women-only dating app, has suffered a massive data breach after its backend was found completely unsecured. Over 72,000 private images and more than 13,000 government-issued IDs were leaked online.

Some documents were dated as recently as 2025, contradicting the company’s claim that only ‘old data’ was affected. The data, totalling 59.3 GB, included verification selfies, DMs, and public posts. It spread rapidly through 4chan and decentralised platforms like BitTorrent.

Critics have blamed Tea’s use of ‘vibe coding’, AI-generated code with no proper review, which reportedly left its Firebase database open with no authentication.

Experts warn that relying on AI tools to build apps without security checks is becoming increasingly risky. Research shows nearly half of AI-generated code contains vulnerabilities, yet many startups still use it for core features. Tea users are now urged to monitor their identity and financial data.

Network failure hits EE, BT and affects other UK providers

Thousands of EE and BT customers across the UK encountered widespread network failures on 24 July, primarily affecting voice services.

The outage, lasting over 24 hours, disrupted mobile and landline calls. Over 2,600 EE users reported issues with Downdetector at peak volume around 2:15 p.m. BST. Despite repair efforts, residual outages were still being logged the following day.

Although Vodafone and Three initially confirmed their networks were stable, users who recently switched carriers or ported numbers from EE experienced failures when making or receiving calls. However, this suggests cross-network routing issues burdened by EE’s technical fault.

Emergency services were briefly impacted; some users could not reach 999, though voice functionality has resumed. BT and EE apologised and said they were working urgently to restore reliable service.

Given statutory obligations around service resilience, Ofcom has opened inquiries into scale and causes. Affected MVNO operators using EE infrastructure, like 1pMobile, reported customer disruptions.

Meta boosts teen safety as it removes hundreds of thousands of harmful accounts

Meta has rolled out new safety tools to protect teenagers on Instagram and Facebook, including alerts about suspicious messages and a one-tap option to block or report harmful accounts.

The company said it is increasing efforts to prevent inappropriate contact from adults and has removed over 635,000 accounts that sexualised or targeted children under 13.

Of those accounts, 135,000 were caught posting sexualised comments, while another 500,000 were flagged for inappropriate interactions.

Meta said teen users blocked over one million accounts and reported another million after receiving in-app warnings encouraging them to stay cautious in private messages.

The company also uses AI to detect users lying about their age on Instagram. If flagged, those accounts are automatically converted to teen accounts with stronger privacy settings and messaging restrictions. Since 2024, all teen accounts are set to private by default.

Meta’s move comes as it faces mounting legal pressure from dozens of US states accusing the company of contributing to the youth mental health crisis by designing addictive features on Instagram and Facebook. Critics argue that more must be done to ensure safety instead of relying on user action alone.
