United Airlines blocks AI agents from booking flights

United Airlines is actively blocking third-party AI agents from accessing its booking systems, marking a significant shift in how legacy infrastructure handles autonomous software. The airline cites cybersecurity risks from shared credentials and potential violations of federal aviation rules requiring human check-ins. This move aligns with similar warnings from major banks like Bank of America, signaling that critical industries are drawing hard lines around where human oversight is legally required. It effectively kills the dream of fully autonomous travel booking for now, forcing a re-evaluation of agent integration in regulated sectors.
