Pulse Analysis

The online travel agency (OTA) market in Europe is dominated by a handful of platforms, with Booking.com holding roughly a 40% share of hotel bookings across the continent. Visibility on these sites is a critical driver of revenue; hotels that appear at the top of search results typically command higher occupancy and rates. Italy’s competition authority, the Autorità Garante della Concorrenza e del Mercato (AGCM), has intensified scrutiny of such practices, arguing that algorithmic favoritism can distort fair competition and harm consumers.

In the latest case, the AGCM alleges that Booking.com’s “preferred partner” program rewards hotels that agree to higher commission fees with more prominent placement in search results. Inspectors, accompanied by the financial police’s antitrust unit, examined the platform’s ranking methodology and found evidence suggesting that paying hotels enjoy a visibility boost. The regulator contends that this practice may mislead travelers into believing higher‑priced options are the best choices, thereby inflating average accommodation costs. Booking.com maintains the program is optional and complies with existing regulations, citing earlier commitments made after a prior probe.

The investigation could have ripple effects throughout the OTA ecosystem. A finding of abuse may compel Booking.com to redesign its algorithm, introduce greater transparency, or face substantial fines under EU competition law. Competing platforms such as Expedia and Airbnb could benefit from a level playing field, while hotels might reassess the value of commission‑based visibility versus direct booking channels. The case also signals to regulators across the EU that algorithmic ranking is a frontier for antitrust enforcement, prompting industry players to pre‑emptively audit their own practices.
