The European aviation industry is entering a new phase of strategic transformation. While passenger demand has largely recovered, airlines, airports and aviation service providers continue to face mounting challenges, including volatile fuel prices, constrained aircraft availability, significant capital expenditure requirements and increasingly stringent environmental regulations. These factors are reshaping industry economics and reinforcing the importance of targeted M&A as a tool to drive growth, resilience and competitive advantage.
European airports welcomed a record 2.6 billion passengers in 2025, representing year-on-year growth of 4.4%. Yet rising traffic volumes do not automatically translate into stronger profitability. According to IATA, European airlines generated net profits of €11.4 billion in 2025, with earnings expected to decline to €8.4 billion in 2026, reducing regional net margins from 4.5% to 3.1%. Against this backdrop, scale alone is no longer sufficient. Transaction value increasingly depends on a buyer's ability to unlock synergies, optimize networks, expand capabilities and enhance operational performance across route portfolios, airport infrastructure, certified aviation services and specialised technology platforms following completion of an acquisition.
The aviation sector consists of a diverse ecosystem of businesses with fundamentally different operating models, risk profiles and value drivers. Network airlines connect passengers through major hubs, while low-cost, regional and leisure carriers focus on distinct customer segments and route structures. Cargo aircrafts, crew, maintenance and insurance companies provide additional operational flexibility and support capacity constraints across the market.
Beyond the airlines themselves, the value chain includes airports, ground handlers, cargo service providers, maintenance, repair & overhaul companies (MROs), aircraft lessors, original equipment manufacturers (OEMs) and specialized aviation suppliers. Each segment generates value through different economic levers. Airlines are primarily exposed to passenger demand, load factors and yields, whereas airports benefit from long-term traffic growth, infrastructure utilization and non-aeronautical revenues. Ground handling and cargo service providers rely on operational efficiency and contractual relationships, while MRO providers and specialist suppliers derive much of their value from certified capabilities, technical expertise, skilled workforces and access to aircraft programs.
These characteristics have important implications for M&A. Airline transactions are often driven by network expansion, slot portfolios, hub positions or access to attractive local markets. Airport investments provide exposure to long-term passenger growth, capacity development and resilient cash flows. Acquisitions of ground handlers, MRO providers or specialist suppliers are typically focused on expanding customer access, increasing operational capacity and strengthening technical capabilities. As a result, investment theses, transaction structures and post-merger integration priorities differ significantly across the aviation value chain, requiring investors to tailor their approach to the specific asset and value creation opportunity.
European air traffic has recovered to pre-pandemic levels, yet growth remains uneven across countries, airports and business models. EUROCONTROL recorded 11.1 million flights in 2025, representing growth of approximately 4% compared to 2024, and forecasts a further increase to around 11.3 million flights in 2026. At the same time, the organisation highlights that geopolitical tensions and airspace disruptions continue to create significant uncertainty for the sector's near-term outlook.
While demand remains resilient, capacity expansion is increasingly constrained. Aircraft delivery delays, engine reliability issues and extended maintenance cycles limit fleet availability across the industry. According to IATA, the global aircraft order backlog exceeded 17,000 aircraft at the end of 2025, while the average age of the active fleet reached 15.1 years. The prolonged operation of older aircraft supports demand for MRO services, spare parts and leasing capacity, while also increasing operating costs for airlines.
Cost inflation remains another key challenge. Fuel represented approximately 25.4% of global airline operating expenses in 2025 and is expected to increase to 31.4% in 2026. While these figures reflect global industry dynamics rather than purely European operators, they highlight the industry's continued exposure to energy price volatility and margin pressure. Against this backdrop, in a M&A buy-side scenario investors and acquirers are placing greater emphasis on resilient business models, pricing power, operational efficiency and aftermarket-related revenue streams. Growth strategies and acquisition cases must therefore remain robust under more challenging cost and capacity scenarios.
Digitalisation is becoming an increasingly important driver of efficiency and value creation across the aviation sector. Advanced analytics, automation and data-driven decision-making can improve aircraft maintenance planning, network optimization, disruption management and the utilization of airport infrastructure. Enhanced operational data enables airlines and service providers to deploy aircraft, personnel, equipment and spare parts more effectively, supporting both cost efficiency and service quality. In a M&A buy-side scenario technology is relevant for investors and acquirers not only as a source of operational synergies but also as a key determinant of integration complexity and future capital expenditure requirements.
Environmental regulation is simultaneously reshaping investment priorities across the industry. Under the ReFuelEU Aviation Framework, fuel supplied at EU airports must contain a minimum share of sustainable aviation fuel (SAF), increasing from 2% in 2025 to 6% by 2030. According to the European Commission, SAF represented 2.8% of aviation fuel supplied in 2025. Compliance requires coordinated investment by fuel suppliers, airlines and airports, increasing the strategic importance of modern fleets, supporting infrastructure and reliable operational data systems.
These developments create both opportunities and challenges across the aviation value chain. Providers of specialized software, automation solutions, predictive maintenance technologies and digital infrastructure may become attractive acquisition targets for larger industry participants seeking productivity gains and operational resilience. However, technology acquisitions deliver value only when successfully integrated into existing operating models. As a result, buyers increasingly assess not only the quality of the technology itself but also the retention of key personnel, scalability of platforms and the ability to realize measurable operational improvements following completion of a transaction.
Large airline groups benefit from the ability to combine multiple brands, hubs and route networks while centralizing functions such as procurement, sales, loyalty programs and fleet management. Broader networks can increase connecting traffic, improve aircraft utilization and provide access to destinations that would be difficult to serve profitably on a standalone basis. Scale also enables the sharing of technology and operational infrastructure investments across a larger platform, supporting efficiency and competitiveness.
At the same time, smaller airlines continue to play an important role within the European aviation ecosystem. Regional carriers, leisure airlines and ACMI operators often occupy defensible niche positions, provide flexible capacity and maintain strong customer relationships in specific markets. Their attractiveness as acquisition targets extends well beyond passenger volumes. Key value drivers include fleet composition, aircraft ownership and lease structures, route economics, airport slots and access rights, seasonality, customer concentration and the ability to maintain regulatory approvals and operating certificates.
However, scale alone does not guarantee value creation. Successful M&A transactions in the airline business depend on the quality of the underlying business model and the extent to which operational, commercial and network synergies can be realized. Acquiring an airline with an unfavourable cost structure, significant fleet-related liabilities or substantial route overlap may increase complexity without generating sustainable returns. As a result, investors and strategic buyers are increasingly focused on assets that strengthen network positions, enhance operational resilience and offer clearly identifiable post-transaction value creation opportunities.
European aviation companies are increasingly reassessing where they can compete most effectively and create sustainable value. Network carriers focus on leveraging hub connectivity and long-haul demand, while low-cost airlines seek to maximise aircraft utilisation, cost efficiency and access to attractive airport bases. ACMI providers support capacity-constrained airlines through flexible fleet solutions, whereas airports and ground handlers compete on operational reliability, network reach and service quality.
Across aviation services, competitive advantage is often driven by specialised capabilities rather than scale alone. For MRO providers, certified technical expertise, engineering talent and regulatory approvals can represent more valuable assets than geographic footprint. Similarly, suppliers with proprietary technologies, long-term program participation or mission-critical products may occupy strategically important positions within the aviation ecosystem. As a result, buyers must assess whether an acquisition delivers genuinely differentiated capabilities, strengthens market positioning or merely increases exposure to existing customer, operational and supply-chain risks.
The implications for M&A are significant. There is no single consolidation model that applies across the aviation value chain. Value creation may stem from network expansion, leadership in a specialized niche, access to regulated infrastructure, long-term concession rights or the financial capacity to invest in technology, sustainability and operational improvements. Successful transactions are therefore defined less by scale itself and more by their ability to enhance strategic positioning, strengthen competitive advantages and create sustainable long-term value.
Recent transactions demonstrate the breadth of M&A activity across the aviation sector and the variety of strategic objectives pursued by both industrial and financial investors.
In the airline segment, consolidation continues to focus on network expansion and market access. Lufthansa acquired an initial 41% stake in ITA Airways in January 2025 and subsequently announced its intention to increase its ownership to 90%, with completion expected in the first quarter of 2027, subject to regulatory approvals. The transaction is intended to generate benefits across route networks, sales channels, loyalty programs and procurement, while preserving ITA's standalone brand. Air France-KLM is pursuing a similar strategy through its planned increase in SAS from 19.9% to 60.5%, seeking deeper commercial integration and a stronger position in the Scandinavian market. Meanwhile, the privatisation process of TAP Air Portugal allowing Lufthansa to take a significant minority stake illustrates the political and regulatory complexity that often accompanies airline consolidation in Europe.
Financial investors also continue to view aviation platforms as attractive investment opportunities. In August 2026, easyJet agreed terms for a recommended acquisition by an Apollo-backed entity, valuing the company's equity at approximately GBP 5.7 billion. Subject to shareholder, court and regulatory approvals, the proposed transaction highlights continued investor confidence in scalable airline platforms and their ability to generate value through operational improvements and portfolio optimisation.
Airport transactions are typically driven by a different investment rationale. Rather than focusing on network synergies, investors seek exposure to long-term passenger growth, infrastructure development and stable cash flow generation. VINCI Airports' acquisitions of a majority stake in Edinburgh Airport and a strategic interest in Budapest Airport reflect this infrastructure-led investment approach and its emphasis on long-term operational stewardship.
Beyond airlines and airports, consolidation is increasingly extending into aviation services and the industrial supply chain. Menzies Aviation's acquisition of the remaining stake in Portuguese ground handler SPdH strengthened its position in airport services, while MTU Aero Engines' acquisition of automation specialist 3D.aero expanded capabilities relevant to aircraft production and maintenance. These transactions underscore a broader trend toward capability-driven acquisitions, where technical expertise, operational know-how and specialised technologies are often as important as geographic expansion.
The sources of value creation in aviation M&A vary significantly across the industry value chain. For airlines, acquisitions can enhance network connectivity, improve schedule coordination, increase connecting traffic and generate efficiencies in procurement, fleet management and distribution platforms. Airport investors may create value through route development, commercial revenue optimization and targeted infrastructure investments that support long-term passenger growth.
In aviation services, consolidation can strengthen customer relationships, expand geographic coverage and improve resource utilisation. Ground handlers may benefit from broader airline relationships, shared training programs and more efficient deployment of personnel and equipment across multiple locations.Within MRO and manufacturing activities, acquisitions can secure access to scarce engineering expertise, certified technical capabilities and critical repair capacity, while also supporting investment in automation and operational efficiency. These advantages are particularly valuable in an environment characterised by constrained aircraft and engine availability.
However, realising these benefits requires careful execution. Aviation remains a highly regulated and capital-intensive industry, where safety standards, certifications and service reliability cannot be compromised in pursuit of synergies. In a M&A scenario, buyers must therefore ensure that capabilities can be scaled without undermining operational performance, regulatory compliance or customer relationships.
The financial investment case must also reflect the sector's significant capital requirements and operational complexity. Key considerations include aircraft lease obligations, maintenance reserves, airport concession agreements, working capital intensity, capital expenditure backlogs, customer contract structures and exposure to fuel and energy costs. As a result, attractive synergy assumptions alone rarely determine transaction success. Value creation ultimately depends on a buyer's ability to integrate systems, align operating procedures, manage labour relationships and successfully execute the post-merger integration plan. Transactions that appear compelling in theory can struggle to deliver expected returns when operational realities prove more difficult than anticipated.
Aviation transactions are subject to some of the most stringent regulatory requirements of any industry. Airline mergers and acquisitions receive particularly close scrutiny because competition is often assessed on individual routes, while access to slots at capacity-constrained airports can determine whether effective competition remains possible. Lufthansa's investment in ITA Airways was approved only after commitments addressing both short-haul and long-haul competition, including the transfer of slots at Milan Linate. By contrast, IAG abandoned its proposed acquisition of the remaining shares in Air Europa following an in-depth review by the European Commission. These cases illustrate how regulatory considerations can significantly influence transaction structure, timing and ultimately deal feasibility.
Ownership restrictions add a further layer of complexity. EU regulations generally require EU-licensed airlines to remain majority owned and effectively controlled by EU member states or their nationals, subject to limited exceptions. Consequently, investors must assess ownership structures, governance frameworks, traffic rights and regulatory approvals alongside traditional financial considerations.
Beyond regulatory matters, operational due diligence is often a critical determinant of transaction success. Buyers require detailed visibility into fleet condition and availability, maintenance records, airport access rights, supplier relationships, safety management systems, labor agreements and dependence on key technical personnel. In airline transactions, operating certificates, traffic rights, slots, customer contracts and loyalty programs frequently represent strategic assets whose value may exceed that of tangible infrastructure.
Successful integration requires preserving the very strengths that made the target attractive in the first place. Airlines may need to retain established brands and local market positioning, ground handling businesses must ensure uninterrupted operational performance, and aviation service providers often depend on the retention of certified engineers, technical specialists and regulatory approvals. As a result, the most successful transactions balance synergy realization with operational continuity. Consolidation creates sustainable value only when financial, strategic and commercial benefits can be achieved without compromising safety, reliability, customer relationships or regulatory compliance.
European aviation is expected to remain an active market for mergers and acquisitions, although opportunities and outcomes will vary considerably across the value chain. Underlying demand for air travel and connectivity continues to support long-term growth prospects, while aircraft supply constraints, cost volatility and decarbonization requirements increase the value of efficient operations, specialised capabilities and access to capital. However, a compelling strategic rationale alone does not guarantee transaction success. Regulatory approvals, execution risks and integration challenges will continue to determine whether announced deals ultimately close and create value.
For investors and strategic acquirers, the most attractive assets are likely to combine strong market positions with scarce operational capabilities, resilient infrastructure characteristics or meaningful barriers to entry. Assessments must extend beyond headline passenger volumes and revenue growth to include route-level profitability, fleet obligations, concession frameworks, customer concentration, regulatory feasibility and the investment required to support future growth and compliance requirements.
For sellers, transaction readiness is becoming increasingly important. Businesses that can demonstrate high-quality financial and operational data, a credible long-term investment strategy and clear ownership of key licences, contracts and technical capabilities are likely to attract stronger investor interest. Resilient margins, experienced management teams and well-defined plans to address fleet modernisation, digitalisation and sustainability requirements will become increasingly important differentiators.
The next phase of European aviation M&A is likely to be characterised by selective consolidation across airlines, airports, aviation services and specialized suppliers. The most successful transactions will not necessarily be the largest, but those where a clear strategic rationale is supported by an executable value creation plan, realistic integration assumptions and a thorough understanding of the regulatory and capital-intensive characteristics that distinguish aviation from most other industries.
BDO advises companies, shareholders and investors across the entire aviation value chain on evaluating strategic options and executing M&A transactions. Our support spans buy-side and sell-side mandates, including target identification, market screening, valuation, transaction preparation, due diligence coordination and deal execution.
Aviation transactions require an integrated assessment of financial performance, operational capabilities and regulatory considerations. Effective transaction processes go beyond financial analysis by identifying the underlying drivers of value, assessing the practicality of realizing synergies and addressing integration requirements before a transaction is completed.
Whether the objective is market expansion, succession planning, capital raising or the acquisition of strategic capabilities, successful outcomes depend on a clear investment thesis, rigorous preparation and disciplined execution. In a sector characterized by high capital intensity, complex regulation and operational criticality, a structured M&A process enables buyers and sellers to make informed decisions and maximize long-term value creation.
