In Part I of our 2026 Aviation Trends outlook, we explored three forces already reshaping the industry: the rise of AI as aviation’s operating layer, the transition of urban air mobility from concept to real-world testing, and the growing role of biometrics in streamlining the passenger journey. Together, these trends highlighted how innovation is moving from experimentation to execution.

In this second and final installment, we turn to three additional forces that will define aviation’s operating reality in 2026 — cybersecurity, sustainable aviation fuels, and supply chain resilience. These trends are less visible to passengers, but they will have a profound impact on cost structures, risk exposure, capacity growth and long-term strategic planning across the industry.
Cybersecurity is no longer a secondary operational concern, it is becoming one of the most strategically sensitive vulnerabilities across global aviation. The aviation and aerospace cybersecurity market is already growing at a double-digit annual rate due to heightened demand for protection of navigation, communication and control systems . This growth is not driven merely by the rising frequency of attacks, but by the expanding exposure surface created by digital transformation: cloud-based systems, remote operations, autonomous vehicles, biometric corridors and increasingly connected aircraft all introduce new points of failure that adversaries can target.
In 2026, these risks will intensify as aviation becomes more entangled in geopolitical tensions. Conflicts, sanctions and growing tech-nationalism are accelerating the development of dual-use military technologies, many of which flow later into civil aviation, while simultaneously increasing the industry’s dependence on sensitive digital infrastructure prone to espionage or disruption . At the same time, fragmentation in global standards and export controls complicates the cybersecurity landscape, forcing airlines, manufacturers and airports to operate across multiple, sometimes competing, regulatory regimes. This fragmentation can delay updates, restrict information-sharing and raise the cost of securing aviation networks.
Startups have begun filling these gaps with aviation-specific cyber solutions, and governments are investing more heavily in defense-linked technologies, yet the ecosystem still struggles to keep up with the pace and sophistication of threats. As aviation systems become more digitized and interconnected, cyber risk becomes systemic rather than episodic: a single breach can now impact fleets, routes, passenger data, aircraft health monitoring and operational continuity across regions.
Taken together, these dynamics point to a more precise outlook for 2026: cybersecurity will evolve into a core determinant of operational resilience, shaping regulatory agendas, cross-border cooperation and investment priorities. Rather than viewing cyber as a defensive necessity, airlines and airports will increasingly treat cybersecurity as foundational infrastructure essential to maintaining trust, protecting safety-critical systems and enabling the next wave of digital innovation across the industry.
We expect environmental regulation and SAF adoption to intensify in 2026, materially impacting airline costs and ticket pricing.
Sustainable aviation fuels (SAF) will become one of the most defining and financially consequential forces shaping aviation in 2026. Although SAF remains the industry’s primary decarbonization pathway, global production is still critically limited, estimated by IATA at only 0.7% of total aviation fuel demand in 2025, and current prices remain three to four times higher than conventional jet fuel. This imbalance between accelerating regulatory pressure and insufficient supply means airlines will increasingly face unavoidable cost structures tied to sustainability. Singapore’s decision to introduce the world’s first nationwide SAF levy in 2026, charging passengers between ~1 USD and 32 USD, illustrates a broader global shift: the financial burden of decarbonization is beginning to move downstream to travelers themselves.
Yet the economic challenge extends far beyond the cost of the fuel itself. According to S&P Global, the biggest barrier to SAF adoption is the massive scale-up cost required, from new production facilities to feedstock sourcing, logistics networks, certification processes and distribution infrastructure. Even with growing political will, the industry lacks the manufacturing and supply-chain capacity needed for meaningful displacement of fossil-based jet fuel. Without substantial long-term policy support, investment incentives and coordinated public–private action, SAF risks remaining a niche product rather than a mainstream solution.
As more governments consider similar measures and airlines face tightening mandates, 2026 is shaping up to be the year in which the true cost of sustainable flight becomes visible across the sector. The limitations in supply, combined with the enormous capital investment required to scale production, will reshape pricing structures, investment priorities and competitive dynamics. Rather than a breakthrough year for SAF availability, 2026 is poised to mark the beginning of a more transparent, measured phase in aviation’s decarbonization journey, one in which the economic realities of scaling SAF become clearer across the industry.
Supply chains in aviation are entering 2026 under sustained and structural stress, and much of it is directly linked to geopolitics. The rise of protectionism and sanctions has fractured the global value chains that aircraft manufacturers and avionics suppliers relied on for decades. Export controls, the US–China trade war and restrictions on Russian technology have forced airlines and aerospace companies to look for alternative suppliers and to invest in more local or “friendly” production, driving up costs and extending development timelines. In avionics and high-tech subsystems in particular, companies report growing difficulty sourcing critical semiconductors and specialty metals, with prices rising sharply and delivery times becoming increasingly unpredictable. At the same time, the geopolitical split is encouraging some countries to consider their own “sovereign” aviation standards, a move that if it deepens could fragment global certification, complicate aircraft development and make it more expensive for airlines to operate fleets that must comply with multiple regulatory regimes.
Major Western manufacturers are already adapting – pursuing strategies to reduce exposure to any single country, while airlines and OEMs are beginning to build buffer stocks of critical electronic components in anticipation of future import disruptions. International bodies such as ICAO and IATA are working to preserve global dialogue on standards and innovation, aiming to prevent technological fragmentation from eroding the efficiency and safety benefits of a harmonized system. At the same time, the experience of past shocks, such as the oil crises of the 1970s that ultimately drove more fuel-efficient engine design, is shaping how leaders think about resilience: the sector increasingly frames supply chain robustness as an innovation objective in its own right, not just a risk-mitigation exercise.
All these signals suggest that 2026 will not resolve aviation’s supply chain challengesת but it will mark a transition toward a more deliberate, resilience-first model. We expect longer lead times for key components, continued cost pressure on aircraft and systems, and slower, more staggered rollouts of new platforms as certification, sourcing and standardization become harder to synchronize across blocs. At the same time, we anticipate accelerated investment in supplier diversification, regional manufacturing hubs and smarter inventory strategies, supported by better data and planning tools. For airlines and airports, this means that 2026 will be a year in which capacity constraints, higher input costs and geopolitical uncertainty remain part of the operating baseline, and where strategic advantage will increasingly come from those who can plan for disruption rather than hope it will fade.
Taken together, the six trends explored across this two-part series reveal a clear and consistent picture of aviation in 2026. Artificial intelligence, biometrics and advanced mobility are accelerating because the system must move faster, operate smarter and handle growing complexity. At the same time, cybersecurity, sustainable fuels and supply chain resilience are intensifying because aviation is becoming more exposed, technologically, economically and geopolitically.
Innovation in 2026 is therefore not driven by optimism, but by necessity. Airlines and airports are being pushed to adapt by external forces that leave little room for delay: regulatory pressure, rising costs, geopolitical fragmentation and increasing digital dependency. In this environment, 2026 emerges as a recalibration point, a year in which aviation must align its long-term ambitions with a more constrained, interconnected and politically complex reality.
The organizations that will perform best in 2026 will not be those chasing every new technology, but those able to integrate innovation into their core operating model: treating AI, cyber resilience, sustainability and supply-chain robustness as foundational infrastructure rather than optional upgrades. In a world where uncertainty is the baseline, competitive advantage will belong to those who plan for disruption, invest with discipline and build systems designed to absorb and not avoid change.
