Your user said yes. United said no.
Imagine you built the perfect travel agent. It finds the cheapest flight, asks your user to confirm, waits for the "yes", and books it. No hallucinations, no surprise upgrades, a human in the loop at every step. As of November 11, United Airlines says that booking is against its rules. And it can cancel it. Not because your agent did anything wrong. Because it's an agent. What actually changed On…
United Airlines has announced it will restrict the use of third-party AI agents for booking flights and other services. The revised Contract of Carriage, effective November 11, 2026, defines an AI agent as any software that takes autonomous or semi-autonomous action without the passenger's approval. This includes AI assistants, AI-enabled browsers, and standalone AI agents.
United prohibits AI agents from making, modifying, or servicing a ticket, as well as purchasing any service or product. The airline also restricts access to its digital platforms and indirectly through travel agencies and aggregators. United cites three reasons for this restriction: potential exposure of sensitive information, unintended purchases or account changes, and the risk of violating FAA and DOT rules, such as flight check-in requiring human acknowledgment of prohibited items.
The airline emphasizes the importance of human supervision and discourages the use of AI agents that act on its systems without permission.
