Italy's antitrust regulator opened probe into Booking.com's 'Preferred Partner' hotel ranking program
Apr 22, 2026Italy's antitrust authority (AGCM) opened an investigation into Booking.com over alleged unfair commercial practices in how it ranks and presents hotels. The probe targets the 'Preferred Partner' and 'Preferred Partner Plus' programs, which Booking.com markets as selecting properties based on service quality and value for money, but which regulators allege actually favor hotels that pay higher commissions with better search placement and visual prominence. Booking.com said the programs are optional and compliant with consumer protection rules; the investigation is ongoing.
