Tdoday’s report that Air India (AI) was deploying AI to save $12 million by deploying 30 AI tools. Only a few years ago, we had covered the fact that collectors had made a digital archive of thousands of airsickness bag – there’s a virtual museum of barf bags. In our piece last year, we had also covered the importance of digital archives for museum. All of these developments give us a sense that the global airline industry stands at a technological inflection point.
According to the International Air Transport Association (IATA), global passenger traffic is projected to surpass 5.2 billion in 2025 — a figure that is more than double the traffic recorded in 2003. Carriers worldwide are racing to digitalize every layer of their operations to accommodate that growth without a proportionate expansion of physical infrastructure. The stakes are considerable: delays alone cost the U.S. airline industry an estimated $33 billion in 2019, while human factors contributed to 80% of all airplane maintenance issues in the same period, leading to flight delays, aircraft damage, and in the worst cases, fatal accidents.
The industry’s response has been a wholesale embrace of digital transformation. SITA’s Air Transport IT Insights 2024 estimates total IT spend at $37 billion for airlines and $8.9 billion for airports, with the expectation of further growth as passenger numbers climb. Digitalization has become a matter of operational survival in the aviation industry.
Why Airlines Can No Longer Afford to Delay Digital Adoption
The structural argument for digital transformation in aviation is compelling and well-documented. According to IATA’s Director General Willie Walsh, with continued growth in international passenger numbers, airlines have little choice but to invest in AI and digital tools: infrastructure has remained essentially unchanged, and growth therefore necessitates more efficient ways of operating.
The core challenge is one of legacy. Most airline Passenger Service Systems trace their logic back to IBM’s Transaction Processing Facility — technology developed in the 1960s. The vast majority of today’s passenger traffic is being processed by systems that predate the volume by decades. This structural mismatch creates inefficiencies, bottlenecks, and fragility that carriers can no longer absorb.
A secondary driver is the evolving passenger. Ninety percent of travellers now use digital technology for bookings, three in four are comfortable storing their passport on a mobile device, and 64% identify shorter airport queues as the single improvement they most desire — data drawn from the SITA 2024 Passenger IT Insights report. Sixty-eight percent of passengers are now digital-first, managing their journeys via mobile apps. Airlines that fail to meet this expectation risk ceding loyalty to competitors who do.
How Artificial Intelligence Is Redefining Airline Operations
According to IATA (2024), automation and AI-driven operational tools can reduce airline operational costs by 10–15%, while simultaneously improving safety and reliability. The applications span the full operational chain: crew rostering, dynamic pricing, disruption management, predictive maintenance, route optimization, and customer service.
IATA’s Chief Information and Data Officer Kim Macaulay has articulated why AI merits the hype it receives. In a piece published on the IATA Airlines platform, Macaulay noted that aviation generates vast swathes of data daily from more than 100,000 flights — covering everything from passenger preferences to technical performance — and that the industry’s longstanding challenge has been how to make use of it. AI, she argued, is materially different from conventional software in its capacity to distil that data into actionable insight at speed.
Delta Air Lines and the Generative AI Frontier
No carrier illustrates the ambition of AI-driven transformation more vividly than Delta Air Lines (DL). Delta has fully migrated its technology infrastructure to the cloud and deployed a generative AI travel assistant called Delta Concierge, with the Fly Delta app recording 1.3 billion interactions in 2024 alone. More than 97% of SkyMiles Medallion members use the app as their primary travel companion.
Delta Concierge entered beta rollout in October 2025 for a select group of SkyMiles members. The tool, embedded within the Fly Delta app, uses generative AI to answer real-time queries about:
- flights
- seating assignments
- gate information
- baggage tracking
- SkyMiles benefits
- loyalty perks
— all through natural language text or voice input….Eric Phillips, Delta’s Chief Information Officer, described the initiative as follows:
“We see Delta Concierge as a natural evolution of the digital experience — a way to create simpler, more personalized, and more intuitive journeys with our customers. By empowering customers to easily find answers to their travel questions with AI, or take action in a simple tap, we empower Delta people to deliver more of the one-on-one, nuanced care that sets us apart.”
The CEO of Delta, EdBastian’s overarching vision for the tool is that it will serve as a thread across the experience of passengers. After all, it is a generative AI personal assistant that combines the context of who passengers are as customers with the deep operational knowledge Delta has accumulated as what it describes as the world’s most reliable airline. A phased expansion is planned to bring additional capabilities to the platform throughout 2026.
Delta is not alone. Qatar Airways released Sama, described as the “world’s first AI-powered digital human cabin crew” in 2024, while American Airlines announced it was testing a generative AI-powered chat assistant in mid-2025 to help customers navigate travel disruptions.
Digital Twins and Predictive Maintenance Keep Aircraft Airworthy
Perhaps the most consequential application of digitalization in aviation is not one that passengers experience directly: the deployment of digital twin technology for aircraft maintenance. A digital twin is a virtual replica of a physical asset that mirrors the real-world asset’s behaviour in real-time, integrating:
- data streams
- simulation software
- AI-driven analytics
…to create a living, evolving model that aids design, operations, and maintenance.
According to a 2025 peer-reviewed study published in the European Journal of Computer Science and Information Technology, digital twins enable airlines to simulate maintenance scenarios, predict component failures, and test repairs without affecting actual aircraft operations. This helps provide unprecedented insights through comprehensive data representation, real-time monitoring, pattern recognition, and predictive modelling. Lufthansa Systems has reported that the global digital twin market in aerospace is projected to reach $9.3 billion by 2026, growing at a compound annual growth rate of 17.8%.
Delta Air Lines’ APEX digital twin programme has been credited with saving the airline eight figures annually and won Aviation Week’s Innovation Award in 2024. At Airbus, more than 50,000 users worldwide now develop models that predict component wear, optimise maintenance schedules, reduce downtime, and extend component life — with the manufacturer describing digital twins as “a cornerstone of our digital transformation“, with the manufacturer posting the following numbers:
| Metric | Numerical Data |
|---|---|
| Connected Aircraft on Skywise Platform | 12,000+ aircraft |
| Global Skywise Users | 50,000+ users |
| Airbus Aircraft Programs Mentioned | A320, A350, A321, A380 |
| Airbus Digital Platform | 3DXperience |
| Manufacturing Facility Mentioned | Hangar 9 |
Rolls-Royce, meanwhile, uses digital twin models for jet engines to predict when specific parts will require maintenance, allowing operators to schedule repairs proactively.
Jekaterina Shalopanova, Chief Business Officer at aviation MRO specialist Aerviva, has was quoted in Aero Time to have said that that “to say that digital twins are a must in aviation MRO would be an understatement. In an industry where every hour of aircraft downtime can cost tens of thousands of dollars, the ability to predict, prevent and schedule AOG events makes for smoother and more cost-effective operations.”
A Deloitte study found that implementing predictive maintenance programmes reduces downtime by 15% and improves labour productivity by 20%.
Biometric Identity and the Paperless Airport
Biometric technology is advancing rapidly from novelty to norm across the global aviation network. IATA (2025) reports that biometric-enabled passenger processing can reduce airport wait times by up to 30–40%. The data from actual deployment bears this out: half of all passengers globally have used biometrics at some point during their journey in 2025 — up from 46% in 2024 and nearly 20 percentage points higher than in 2022, with passenger satisfaction at its highest recorded level.
IATA’s One ID initiative advances a vision of a fully paperless journey in which passengers control their own digital identity from check-in to boarding. Leading airports including Singapore Changi, London Heathrow, and Hartsfield-Jackson Atlanta International Airport (ATL) are deploying biometric boarding and facial recognition to streamline processing while maintaining rigorous security standards.
In the United States, the Transportation Security Administration (TSA) has expanded its Digital ID programme to more than 250 airports, and Apple has announced a forthcoming feature enabling users to create a digital ID from their passport for use at select TSA checkpoints.
Emirates (EK) invested $23 million in end-to-end biometric infrastructure at Dubai International Airport’s (DXB) Terminal 3 in late 2025. The International Civil Aviation Organization (ICAO) is simultaneously developing the Digital Travel Credential (DTC), a standard that would allow passengers to verify their identity without physical passports or boarding passes. According to SITA’s 2024 Air Transport IT Insights report, nearly half of all airports plan to implement biometric identity management systems by the end of 2026.
The Widening Cybersecurity Threat Surface
In 2025, ransomware attacks against airlines and airports surged by more than 600% year-over-year According to the Allianz Risk Barometer (2025), 38% of aviation industry respondents now identify cyber loss as their primary concern, surpassing all other categories of risk.
The operational consequences of inadequate cyber resilience have been starkly demonstrated by recent incidents. In August 2024, a ransomware attack by the Rhysida group disrupted operations at Seattle-Tacoma International Airport (SEA), halting check-in and ticketing services for several days, exposing the data of more than 90,000 individuals.
In July 2024, Delta Air Lines was compelled to cancel thousands of flights when a faulty software update from cybersecurity vendor CrowdStrike caused approximately 8.5 million Microsoft Windows computers to fail; the airline subsequently filed a $500 million lawsuit against CrowdStrike seeking damages. Boeing fell victim to a LockBit ransomware attack in 2023, which resulted in the public disclosure of sensitive company data after a $200 million ransom demand was refused.
The threat taxonomy extends beyond ransomware. GPS spoofing — a technique that exploits weaknesses in an aircraft’s navigation systems — resulted in more than 465 reported incidents in India alone between 2023 and 2025.
In 2025, Air France (AF) and KLM Royal Dutch Airlines (KL) reported a breach of a customer service platform, with their combined statement confirming: “IT and security teams, along with the relevant external party, took immediate action to stop the unauthorized access.”
The airline industry has broadly escalated investment in response: SITA reports that 74% of airlines and 72% of airports forecast an increase in overall IT spend in coming years, with cybersecurity and biometrics listed as leading priorities.
Digitalization In the Cockpit, Cabin, and On the Ground
Digital technology is also set to provide more efficient and effective communication between the cockpit, cabin crew, and ground operations, while devices allow instantaneous data exchange. It is hoped that this change will place more informed eyes on critical information at every moment of a flight given that human factors have historically been implicated in 80% of maintenance irregularities.
On the ground, the stakes are equally high. Ground operations link multiple aspects of a passenger journey and the coordination demands are considerable. Digital platforms that put real-time operational data in the hands of ground crews reduce the potential for miscommunication and delay. IoT-enabled sensors in particular are providing real-time aircraft health monitoring and addressing common ground-level issues such as lost baggage and flight delays. Virgin Atlantic (VS), for example, deployed IoT technology across its Boeing fleet and cargo operations, reducing delays by 20% and cutting operational working hours by two per rotation.
Training has also been transformed. Online modules and assessments have superseded paper-based manuals, allowing airlines to track trainee progress, identify at-risk personnel, and deploy corrective learning materials instantaneously. IoT connectivity in aviation is projected to reach $1.94 billion by 2025. Predictive maintenance powered by IoT and AI can foresee potential aircraft issues before they become critical.
Investment Scale, Market Trajectory, and What Lies Ahead
The financial dimensions of aviation’s digital transformation are considerable. SITA’s 2023 report indicated that airlines collectively invested $34.5 billion in IT in that year, with over two-thirds of Chief Information Officers expecting continued technology spending growth into 2024. The global airlines market grew from $523 billion in 2023 to an anticipated $566 billion in 2024 — an 8.2% CAGR — with digital transformation cited as a key driver, and forecasts projecting the market will reach $794 billion by 2028.
Seventy percent of airlines expect to deploy biometric travel solutions across major touchpoints by 2025, while 83% plan to adopt Sustainable Aviation Fuel as a core part of their carbon-reduction strategies. Gartner (2025) estimates that more than 50% of aviation roles will require significant digital upskilling by 2027, particularly in AI operations, cybersecurity, data analytics, and systems engineering. CAE’s 2025 forecast projects 1.465 million new aviation professionals will be needed over the next decade, a workforce pipeline that must itself be built and trained using many of the same digital tools the industry is deploying operationally.
The most forward-looking carriers are moving beyond incremental digitization toward what IATA describes as a digital-first posture. Leslie Thng, CEO of Scoot, asserted at IATA’s World Data Symposium that a truly digital airline must embody a digital-first approach rather than simply digitizing existing processes. This is ultimately set to eliminate the need for physical passports as data is securely processed in advance, permitting seamless airport transit.
