United Airlines blocks AI agents from booking flights, citing cybersecurity risks

United Airlines said it will restrict access to AI agents that book flights and manage reservations on users' behalf, citing cybersecurity risks and concerns about undermining federal regulations. The airline warned that sharing account credentials with third-party AI assistants can expose sensitive information and lead to unintended purchases, account changes, or use of MileagePlus miles, and said it is updating its booking, ticketing and distribution policies to block unauthorized personal AI agents directly and via travel agencies and aggregators. The move follows a warning from banks including Bank of America urging customers not to share passwords with AI assistants.
