The landscape of European mobility is undergoing a tectonic shift. As sustainability mandates tighten and carbon-conscious travelers increasingly shun short-haul aviation, private equity titan Certares is positioning itself at the epicenter of a multi-billion-euro transition. Greg O’Hara, the founder and senior managing director of the firm, confirmed this week that his organization has deployed approximately $2.3 billion into the European and UK rail sectors, signaling a firm belief that the future of intra-continental travel lies firmly on the tracks.

Speaking via video link from the Italian headquarters of train manufacturer Hitachi during the Skift Transatlantic Summit in Dublin on October 15, 2026, O’Hara outlined a strategic vision that treats high-speed rail not merely as a public utility, but as a high-growth investment vehicle poised to capitalize on restrictive environmental legislation.


Main Facts: The Strategic Pivot Toward Rail

The core of the Certares thesis is rooted in the "modal shift"—the intentional movement of passengers from aircraft to trains for short-to-medium-range journeys. According to O’Hara, the regulatory climate in Europe is moving in a singular direction: the systematic phasing out of short-haul domestic flights in favor of high-speed rail networks.

Certares, known for its deep footprint in the travel and hospitality sectors, has transitioned from a traditional travel-focused investor to an infrastructure-heavy player. By securing a competitive position as a "challenger" to national incumbents like France’s SNCF, the firm is betting that market liberalization and regulatory pressure will drive profitability in a sector long dominated by state-owned monopolies.

"We like trains because France has passed a law, and other European countries are going to pass a law that if it’s within a certain distance, you can’t fly there anymore," O’Hara told attendees at the summit.

The firm’s strategy involves aggressive partnerships, most notably its collaboration with Italian rail giant Ferrovie dello Stato. By operating as a challenger, Certares aims to inject private sector efficiencies into historically bureaucratic rail systems, offering better service, dynamic pricing, and seamless integration with the broader travel ecosystem.


Chronology: From Legislative Precedent to Market Disruption

The current wave of rail investment did not emerge in a vacuum; it is the culmination of years of environmental policy evolution.

The Legislative Catalyst (2020–2024)

The journey began with the French government’s push to reduce carbon emissions. In 2021, as part of its Climate and Resilience Law, France moved to ban domestic flights on routes where a train journey of less than 2.5 hours exists. This policy was formally approved by the European Commission in 2022 and came into full effect shortly thereafter. While initially met with skepticism by some aviation lobbyists, the law set a clear precedent for the European Union.

The Investment Surge (2024–2026)

As the French model proved viable, other nations—including Spain, Germany, and the Netherlands—began exploring similar legislative frameworks. Investors took note. Between 2024 and 2026, Certares began its massive capital deployment. The firm identified that while the aviation industry faces rising taxes on carbon and stricter "green" mandates, the rail sector is benefiting from massive state subsidies and infrastructure improvements funded by the European Green Deal.

The Present Moment (October 2026)

At the Skift Transatlantic Summit in Dublin, O’Hara provided the most granular look yet at his firm’s $2.3 billion commitment. The discussion, titled "Where Transatlantic Travel Capital Goes Next," highlighted that the investment isn’t just in rolling stock, but in the operational infrastructure required to compete with national rail champions.


Supporting Data: Why Rails Outperform the Runway

The economic logic supporting the shift toward rail is backed by a convergence of technological advancements and changing consumer behavior.

1. The Cost of Carbon

The aviation industry is grappling with the "flight shame" (flygskam) movement, which has gained significant traction among corporate travelers. Furthermore, the cost of Sustainable Aviation Fuel (SAF) remains high, and carbon credit requirements are making short-haul flights increasingly expensive to operate. Rail, by contrast, is largely electrified and benefits from the decarbonization of the European power grid.

2. Time Efficiency and Convenience

While critics often point to the slow speed of legacy rail, high-speed rail (HSR) provides a vastly different experience. HSR links city centers directly, bypassing the long commute times associated with airports located on the urban periphery. When accounting for security lines, boarding times, and transit to/from airports, a 2.5-hour train ride is often more efficient than a 1-hour flight.

3. Investment Volume

Certares’ $2.3 billion investment reflects a broader trend. Infrastructure funds, pension funds, and private equity firms are increasingly viewing rail as a "defensive" asset. Unlike the cyclical nature of hospitality or aviation, rail demand is inelastic; it is essential for the movement of goods and labor, making it a stable long-term play in an uncertain macroeconomic environment.


Official Responses and Industry Sentiment

The announcement has triggered a wave of responses from stakeholders across the transport spectrum.

From the Aviation Sector:
Industry representatives, such as the International Air Transport Association (IATA), have cautioned that a "blanket ban" on short-haul flights could stifle connectivity, particularly for regional economies that rely on feed-in flights to major hubs like Paris-Charles de Gaulle or Frankfurt. Aviation leaders argue that the focus should be on hydrogen and electric flight technology rather than forced modal shifts.

From the Rail Sector:
Incumbent operators, while initially resistant to the entry of private challengers, have begun to adapt. The arrival of companies like Certares has pushed incumbents to modernize their loyalty programs, improve digital ticketing, and optimize their schedules. "Competition is healthy," said an executive from a major European rail operator who requested anonymity. "It forces us to treat passengers as customers rather than captive users."

The Regulatory Stance:
European Union regulators maintain that the shift is non-negotiable if the bloc is to meet its 2050 climate goals. Brussels is currently drafting guidelines to harmonize high-speed rail standards across borders, which will further facilitate the operations of private entrants like those backed by Certares.


Implications: The Future of Transatlantic Travel

The implications of Certares’ strategy extend far beyond the European continent. If the model proves successful—that is, if private rail challengers can achieve profitability while maintaining high service standards—it could fundamentally alter how Americans and international travelers navigate Europe.

The "Seamless Trip" Evolution

In the near future, the "Transatlantic journey" may look very different. A traveler flying from New York to Paris might find their final destination ticket to Lyon or Bordeaux integrated directly into their airline booking. This "intermodal" travel—seamlessly linking long-haul air travel with high-speed rail—is the next frontier for firms like Certares.

A Template for Global Markets

If O’Hara’s thesis holds, the European model will likely be exported. Countries with high population densities and existing rail infrastructure—such as Japan, China, and parts of the United States (notably the Northeast Corridor)—are watching the European experiment closely. If private equity can successfully capture the rail market, the "Flight-to-Rail" transition could become a global standard within the next decade.

Economic and Environmental Impact

For the environment, the implications are profound. Replacing millions of short-haul flight seats with electric train capacity is one of the most effective ways to reduce the carbon footprint of the tourism industry. For the economy, it represents a massive reallocation of capital toward sustainable infrastructure, potentially creating a new "Golden Age" of rail travel.

Final Thoughts

As Greg O’Hara concluded during the summit, the writing is on the wall for short-haul aviation. The combination of legislative mandates, technological advancements, and a $2.3 billion vote of confidence from a firm as influential as Certares suggests that the train is no longer just an alternative—it is becoming the primary choice for the discerning, environmentally conscious traveler. The era of the "challenger railway" has arrived, and it is reshaping the continent one kilometer at a time.
