United Airlines announced on November 11 that it will block personal AI agents from booking flights. The agents can search for fares and show results, but they cannot complete the purchase. TechCrunch reports United cited data security and federal rules.
The agent cannot give the attestation
United gave one example. Breitbart reports an AI agent cannot attest during check-in that a passenger's bags contain no explosives. The rule stays with the traveler. The agent cannot stand in for the person.
The Washington Post reports United said sharing details with third-party AI assistants can expose sensitive information. Actions taken by those tools may result in unintended purchases or changes to customer accounts. CNBC reports automated AI tools performing actions like flight check-in could create regulatory risks.
The airline can already trace the source
Breitbart reports United said its back-end technology can already tell whether a booking came from an individual. The system also identifies bookings from a traditional travel agency or an AI agent. The airline is not seeing many bookings coming through AI agents at all. The carrier said it will keep evaluating the tools as personal AI assistants develop.
BetaNews reports United updated its contract of carriage on November 11. Agents may still look up schedules and show prices, but a person must finish the purchase. The airline can cancel without notice any reservation that an AI agent created, altered or handled.
Other airlines let customers decide
Forbes reports Delta, American and JetBlue allow customers to book flights with AI agents. The customer assumes the risk. American Airlines said some AI agents, including Meta's Muse, can already buy tickets through certain partners. Customers can direct an AI agent to complete a booking directly on American's website.
BetaNews reports the prohibition applies on United's website and app. The airline is also moving against agents that come in via aggregators or travel agencies. United issued a broader call to other companies. It said they should consider measures that preserve customer data and security.
Where the attestation gate would go
Atelier's agent asks for approval before it sends, posts or drafts an email. If it could book a flight, I would need a gate before checkout. I would need another before check-in. The TMA Family App takes payments through PayPal checkout. I would check whether the treasurer can tell an agent purchase from a member purchase.
AI Trader runs with autopilot off by default. Each new order waits for approval. A travel agent would need the same switch. United is blocking agents because it cannot verify one thing. It cannot tell whether the person behind the agent approved the specific action. The airline can tell an agent booked the trip. It cannot tell whether you told it to. Banks reported the same problem in October.
Google gave its Gemini agent a Workspace account on October 8. The agent got its own email address and a directory listing. United cut the agent off before the purchase.
The agent can attest to the bag.
Somewhere an AI assistant is about to click through a hazmat disclosure. It will do so on behalf of a passenger. That passenger did not read it. United decided that liability is not theirs.
