Change Summary
Booking.com's Terms and Conditions document appears to have been replaced with an error page or security challenge page on May 9, 2026. The substantive terms of service content, which previously totaled over 1,500 sentences, is no longer accessible through the normal document view. Instead, users see a JavaScript-dependent security verification interface. This means the actual binding terms governing your use of Booking.com are currently not publicly readable in their standard format.
