€360 Billion Required to Modernize European Airports

European airports will require approximately €360 billion in capital expenditures by 2040 to upgrade terminals, runways, security systems and sustainability infrastructure in order to meet projected regulatory and climate-driven requirements.

Key findings: scale and timing of the investment shortfall

The joint ACI EUROPE – Boston Consulting Group (BCG) analysis outlines that the European airport network faces a combination of slower traffic growth, higher compliance and operational costs, and downward revenue pressure. The study quantifies a funding need of €360 billion by 2040, driven by modernization, resilience projects and decarbonization-related upgrades such as SAF supply infrastructure and enhanced energy systems.

BCG’s financial modelling highlights a potential erosion of between €45 billion and €75 billion in cumulative EBITDA over the next two decades if current trends continue without policy or commercial corrective measures. The implication is that many airports will be unable to self-finance required investments from operating cash flow alone.

Immediate regulatory and operational measures recommended

The report presented at a New Year reception hosted by Members of the European Parliament Nikolina Brnjac and Jan-Christoph Oetjen sets out a series of policy interventions intended to shore up airport financial models and preserve connectivity:

• Revise slots rules in the EU and the UK following recommendations in the Draghi report to improve utilization and competitive access.
• Preserve operating aid for smaller regional airports within EU State aid Guidelines to protect network connectivity.
• Implement the EU Sustainable Transport Investment Plan, including a Book & Claim mechanism for Sustainable Aviation Fuels (SAF) to lower lifecycle emissions.
• Support biometrics and security enhancements through targeted regulation to improve efficiency and passenger throughput.
• Deliver stability in airport charges via predictable EU regulation to facilitate long-term finance planning.

Projected financial impacts at a glance

Who bears the risk?

Smaller regional airports and single-asset airport operators are most vulnerable because they have limited revenue diversification and smaller access to capital markets. Major hub airports may be better positioned but face substantial modernization bills and regulatory scrutiny around charges and market power.

Historical context: how airport finance evolved into a structural challenge

The current moment follows decades of transformation in airport governance and funding models. Historically, airport investments were often funded through a mix of state capital, airport charges and concession revenues. From the 1990s, many European airports pursued corporatization and privatization to access private finance and expertise. This shifted the balance toward user-charge funded models and private-sector investment in terminals, retail and services.

More recently, two structural trends have altered the economics: first, decelerating passenger growth driven by climate policy and modal shifts; second, the increasing capital intensity of compliance and sustainability measures—particularly the transition to SAF, electrification of ground operations and enhanced climate resilience for runways and coastal airports. These together compress margins while increasing capital needs.

Regulatory shifts that matter

Key regulatory touchpoints include airport slot allocation rules, state aid frameworks for regional connectivity, and common approaches to airport charges. The push for predictable rules and an overarching EU Aviation Strategy aims to create a more stable investment environment; however, implementation and political consensus remain open questions.

Implications for tourism, coastal resorts and boating destinations

Transport connectivity is a core enabler of tourism demand. The investment gap at airports can have ripple effects on access to leading beach and island destinations, potentially raising costs or reducing service frequency to secondary gateways that feed marinas, resorts and coastal activities. Conversely, well-targeted investment in regional airports can preserve or even expand access to destinations popular with travelers seeking beaches, lakes and marine activities.

For stakeholders in yachting and coastal tourism ecosystems, airport accessibility affects seasonality, charter flows and the ability of crews and guests to reach marinas quickly. Upgrades to security, passenger processing and intermodal links (rail and road) that reduce transfer times can enhance the attractiveness of a region for high-end tourism and related services.

Practical checklist for regional tourism planners

• Engage with airport authorities on slot and schedule consultations to protect seasonal services.
• Advocate for state aid provisions that secure year-round connectivity to secondary airports.
• Invest in intermodal links—shuttle, rail, road—between airports and coastal marinas or resorts.
• Monitor SAF rollout and logistics plans that could affect freight and fuel availability for island or remote ports.

Outlook: cautious forecast for international tourism and connectivity

If recommended policy changes are implemented—stable charge frameworks, support for regional connectivity, and targeted SAF infrastructure—air connectivity across Europe can be maintained with manageable cost impacts. Without these actions, expect a modest contraction in point-to-point services to smaller destinations, greater concentration of growth at large hubs, and increased pressure on pricing that could reshape tourist flows over the next 15 years.

Ultimately, the sector’s ability to bridge the €360 billion gap will determine whether airports remain facilitators of broad destination access or consolidate into fewer, better-funded hubs. The implications extend to international tourism: destinations, marinas and coastal economies will be winners or losers depending on the balance of public policy and private investment.

The ACI EUROPE–BCG findings underline the strategic link between transport infrastructure and tourism outcomes: investment decisions at airports influence destination accessibility, seasonal connections to beaches and lakefront resorts, the viability of regional activities, and the broader competitiveness of travel and leisure offerings across Europe. Stakeholders from public authorities to port and resort operators should watch how policy and financing choices play out, because they will shape which destinations thrive and which face declining connectivity.
