No, Priceline and Expedia are two separate, competing corporations that dominate the online travel agency (OTA) market. Expedia Group is a massive conglomerate that owns brands like Hotels.com, Vrbo, Orbitz, and Trivago. On the other hand, Booking Holdings (formerly the Priceline Group) owns brands such as Booking.com, Kayak, Agoda, and OpenTable. While both companies offer similar services—allowing you to book flights, hotels, and car rentals—they operate as distinct entities with different business models and regional strengths. For example, Expedia has historically had a stronger presence in the North American market, while Booking.com (under the Priceline/Booking Holdings umbrella) is often cited as the leader in European and international hotel inventory. As a high-value peer tip, it is always worth checking both sites (and their "secret deal" sections) because they often negotiate different exclusive rates with hotels, meaning the price for the exact same room can vary significantly between the two "travel titans."
