United Airlines Restricts Third-Party Personal AI Agents from Booking Tickets

On November 11, 2026, United Airlines prohibited third-party personal AI agents from booking tickets on its app and website, and restricted travel agencies and aggregator platforms from indirectly using such tools; the restriction also applies to bots, browser extensions, and browser features that act on customers' behalf on United channels without permission. United said that sharing account credentials may leak sensitive information, and that automated operations may also violate FAA and DOT regulations, for example check-in requires manual confirmation that baggage does not contain prohibited items; agent orders already completed previously will not be canceled. On November 12, United said that for regulatory and consumer safety considerations it will restrict third-party AI agents' access, covering its own digital platforms as well as indirect access through online travel agencies and aggregator platforms. On the same day, another report said that United, citing data security and compliance, prohibits personal AI agents such as Instinct and Meta's Muse from booking its flights through direct and indirect channels; bookings completed by AI agents on customers' behalf before November 11, 2026 are still recognized, and United has not reached any authorization agreement with any agent party.
