Booking.com acts as an intermediary (an online travel agency), meaning that the primary responsibility for a refund usually lies with the "Service Provider" (the hotel, airline, or car rental company). When you make a booking, the cancellation and refund terms are set by that provider, not by Booking.com itself. If you book a "Non-Refundable" rate, Booking.com cannot force a hotel to return your money. However, if the service provider initiates the cancellation or if there is a verified billing error, Booking.com will facilitate the refund process. In 2026, many airline tickets purchased through the portal are subject to new "look-in" options and 48-hour cancellation windows mandated by civil aviation authorities. If a provider refuses a legitimate refund, Booking.com’s customer service may intervene, but their role is primarily to mediate based on the specific policy agreed upon at the time of booking. It is essential for travelers to carefully review the "fine print" on their confirmation email to see if their specific reservation is "Fully Flexible" or "Partially Refundable."
