The global aviation industry is undergoing a technological upgrade of historic proportions. According to SITA's latest Air Transport IT Insights report, the industry invested a record $50,8 billion in information technology last year.
Despite these massive expenditures, the study identifies a key obstacle hindering the full realization of investment potential: the lack of coordination and integration of operational data across system and partner boundaries. While airlines and airports alike are increasing their budgets to enhance operational resilience, technological advances in artificial intelligence, cybersecurity, and digital identities are stagnating where information remains in isolated silos. Given global instability and the rising costs of flight delays, creating a consistent data infrastructure is now at the heart of strategic planning for industry leaders worldwide.
Record investments in a beleaguered industry
The aviation industry is currently operating under considerable economic and operational pressure. Geopolitical tensions, particularly in the Middle East, are leading to diversions and unpredictable disruptions to flight schedules. In this environment, IT investments are no longer a luxury, but a necessity for survival. Airlines have increased their spending to US$36 billion, which is approximately 3,6 percent of their total revenue. The increase is even more pronounced for airports, which raised their IT investment ratio from 6,4 percent to 7,3 percent of revenue, totaling US$14,8 billion.
David Lavorel, CEO of SITA, emphasizes that the mere availability of technology is not enough. The problem lies in the lack of connectivity. Where data does not flow freely between partners, investments currently drive up costs rather than reducing them. Nevertheless, 83 percent of airlines and 89 percent of airports have declared data-driven decision-making a strategic priority. This underscores the industry's awareness that operational excellence can only be achieved through a solid information foundation.
The financial consequences of a lack of integration
Operational reliability has become a direct driver of financial performance. In a system operating at its capacity limits, even the smallest disruption cascades down the entire network. According to data from the International Air Transport Association (IATA), delays result in an annual revenue loss of approximately $30 billion across the industry. To minimize these losses, 46 percent of airlines are modernizing their flight operations systems. The goal is to consolidate information about aircraft, crews, and passengers in real time.
However, 49 percent of companies face the problem of data inconsistency. When information is scattered across different platforms, the window for preventative action often closes before those responsible can react. Seamless integration would make it possible to catch delays before they become a system-wide problem. Infrastructure modernization therefore aims to provide all operational teams with a unified overview of the situation.
Artificial Intelligence: Between Ambition and Reality
A particular focus of current IT strategies is on artificial intelligence (AI). While previous applications were often limited to isolated areas such as route optimization or predictive maintenance, the focus is now shifting towards holistic operational management. Already, 63 percent of airlines use AI-supported systems to simultaneously manage aircraft allocations, crew availability, and disruptions. Furthermore, 79 percent of companies have defined generative AI and large language models as top priorities for the coming year.
However, practice reveals a significant gap: AI is most reliable when operating within a closed system. As soon as decisions rely on data from external partners, the adoption rate drops rapidly. For example, only 17 percent of airlines use AI for real-time monitoring of ground handling. Airports are already a step ahead, using AI in 53 percent of their handling processes. The technological maturity of AI models currently exceeds the quality of the available data infrastructure, which limits the usefulness of the algorithms.
Cybersecurity as a shield for shared data repositories
With the increasing interconnectedness of systems, the attack surface for cybercrime also grows. A security incident at one partner can now jeopardize the integrity of the entire information chain. Gate changes, passenger data, and check-in status are highly sensitive pieces of information upon which the entire operation depends. For 71 percent of airports, cybersecurity is therefore a top priority.
The industry is responding to this threat by deploying intelligent defense mechanisms. Sixty-four percent of airports already use AI-based security solutions to detect anomalies in network traffic at an early stage. This represents a significant increase compared to the previous year. Infrastructure modernization is thus increasingly driven by the need to secure shared data platforms against external manipulation.
Another growth path is the introduction of digital identity solutions for passengers. Sixty-four percent of airlines plan to introduce digital IDs, and biometric border controls are expected to be standard at 83 percent of airports by 2028. While the technical implementation is considered secure, the actual benefit for passenger flow depends heavily on coordination between stakeholders. Fifty-seven percent of airlines state that cooperation with airports is the most important prerequisite for scaling these programs. A biometric system is only efficient if the traveler's identity is consistently recognized at every touchpoint – from check-in and security to boarding. Without this coordination, the expensive infrastructure remains untapped potential.
