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

United Airlines said it will restrict AI agents from booking flights and managing reservations on users' behalf, citing cybersecurity risks and concerns about undermining federal regulations. The airline said 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 it is updating booking, ticketing and distribution policies to block such access directly and through travel agencies and aggregators. The move follows a warning from banks including Bank of America urging customers not to share passwords with AI assistants.
