Is a structured data stream that uses the XML (eXtensible Markup Language) format to transmit travel content—such as hotel rates, room availability, flight schedules, fares, and product descriptions—between different systems in a standardized, machine-readable way. Within the realm of travel operations and distribution, it functions as a technical “bridge” that allows online travel agencies (OTAs), tour operators, metasearch engines, channel managers, and global distribution systems (GDSs) to exchange information quickly and consistently, without the need for manual updates.
In practice, it underpins much of the invisible infrastructure that makes modern booking journeys feel seamless. When a traveler searches for a room in Barcelona or a flight to Tokyo, the results presented—live prices, room types, promotional offers, cancellation policies—are often populated via this type of feed, pulling data directly from hotel central reservation systems (CRS), airline inventory, bedbanks, or wholesalers. Because the structure of the data is standardized, receiving platforms can automatically interpret, categorize, and display the content in a coherent way across thousands of properties and routes.
For suppliers and distributors, it is crucial to operational efficiency and revenue optimization. Hotels use these feeds to push real-time rate and availability updates to OTAs and channel partners, reducing overbookings and rate disparities. Airlines rely on similar connections to distribute fares and schedules across multiple sales channels. Destination management companies (DMCs) and tour operators integrate such feeds from various suppliers to dynamically assemble multi-component packages—combining accommodation, transport, and activities into bookable itineraries.
Its significance extends beyond simple connectivity: it enables automation at scale. Large-volume partners can connect once via a feed instead of managing countless individual contracts and manual uploads. This supports dynamic pricing strategies, instant confirmations, and rapid deployment of new products or promotional campaigns across global markets. While newer standards such as JSON APIs and NDC (for airlines) are increasingly common, this format remains deeply embedded in the travel ecosystem, especially in legacy systems and long-established distribution infrastructures.
Example: “The OTA integrated the hotel chain’s XML feed to display real-time room availability, rates, and special offers across all of its regional websites.”
