Booking Holdings operates a portfolio of leading online travel and dining reservation platforms including Booking.com, Priceline, Agoda, KAYAK, and OpenTable, which enable consumers to search, plan, and book accommodations, flights, ground transportation, activities, and restaurant reservations across global markets. The company generates revenue primarily through merchant commissions and transaction fees on bookings—with accommodations being the largest revenue source—as well as agency commissions where the company does not facilitate payments, advertising referral fees, and subscription revenues from restaurant management services. Competing against technology giants, traditional travel agencies, and other online travel platforms, Booking Holdings leverages its portfolio of trusted brands, global scale, technological innovation, and multi-brand strategy to serve customers worldwide.
