United Airlines to block AI agents from managing reservations and flight purchases

United Airlines will block AI agents from managing customers' reservations and flight purchases, citing cybersecurity and privacy risks and potential violations of FAA and DOT rules. 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 applying the restrictions across its own platforms and through aggregators and agencies. Bank of America made a similar warning last week, while Trua CEO Raj Ananthanpillai argued that blocking agents only delays the shift toward verified identity tokens.
