Regulatory scrutiny surrounding Booking expands across Europe
Booking, the online travel platform that connects hotels with travelers seeking rooms, has faced a record 412 million euro penalty from Spain’s National Market and Competition Commission. This action marks the largest fine ever issued by the Spanish antitrust body and signals increasing European attention to how the hotel search engine operates.
In recent years regulators have signaled that Booking must align with broader European competition rules. Earlier this year the European Commission designated Booking as a guardian of a digital intermediation service, enforcing the strict antitrust provisions of the Digital Markets Act. The aim is to ensure fair behavior in a market where Booking holds significant influence, including prohibiting preferential treatment of its own services over those offered by third parties.
Beyond the EU, concerns have surfaced in other jurisdictions. In September 2017, the Swiss competition authorities opened an inquiry into Booking’s commission levels. Results from that inquiry could prompt margin reductions in Switzerland, as Booking disclosed in its latest semiannual results presentation. The report highlighted performance in the United States, noting a semiannual end of the night briefing in Norwalk, Connecticut, on the East Coast.
Further regulatory attention followed in the years after, with investigations launched in July 2023 by the Polish Office of Competition and Consumer Protection focused on hotel host identification and consumer communications tied to obligations to customers. In March 2024 the Italian Competition Authority opened a case to examine whether certain Booking practices might adversely affect hotels and other online travel agencies, mirroring concerns raised in Spain.
Booking has publicly commented that potential findings from any investigation could lead to substantial penalties, restrictions on business practices, or the adoption of other commitments. At the same time, the company reported robust financial results, noting a 47.6 percent year-over-year rise in earnings for the first half of the year, to over two billion dollars on the back of growing travel demand.
In Spain, the CNMC’s action targeted a range of concerns, including pricing clauses that favoured Booking and the imposition of English terms for contracting. The regulator also pointed to a priority given to higher-volume hotels in search results. Industry leaders expressed relief that the decision sets a clear precedent, illustrating that global platforms must respect the rights of service providers and the boundaries of applicable law.
The broader industry recognizes the value of large platforms but insists on fair play. Stakeholders have called for a competitive environment where rules apply equally to all players, ensuring that smaller hotels have access to the same visibility and opportunity as larger suppliers. This debate underscores the push toward transparency in how search rankings are determined and how discounts are presented to consumers.
Regulators in the United Kingdom and across Europe have also pursued consumer-protection commitments. Booking has agreed to voluntary measures, such as making pricing and mandatory charges visible, sharing more information about revenue earned in search result rankings, and adjusting how discounts are displayed to travelers. Regulators stress that these steps are designed to improve clarity and competition while safeguarding consumer interests.
Looking ahead, authorities anticipate that future inquiries may arise in other jurisdictions. Booking acknowledges that new settlements or investigations could require changes to its operations, with possible consequences for its business, competitive standing, or broader online commerce. The company cautions that any additional commitments, fines, or damages could affect financial performance and operational results, though it continues to emphasize growth in key markets.
Overall, the ongoing regulatory dialogue reflects a broader shift toward ensuring that digital marketplaces operate with transparency, fairness, and accountability. As scrutiny intensifies, platforms like Booking face an intensified obligation to demonstrate neutral behavior, provide clear information to both consumers and providers, and maintain a level playing field across borders and business models.
