CHICAGO, Nov. 11 — United Airlines on Wednesday became the first US airline to bar personal artificial intelligence agents from booking its flights, rewriting its Contract of Carriage to block the software from buying tickets, seats and upgrades.
The Chicago-based carrier said the ban covers unauthorised third-party AI assistants on its website and app, and through travel agencies and aggregators, citing data security and federal check-in rules ahead of the holiday travel season.
Key Takeaways
- Rule 6.J.6, added Nov. 11, bars AI agents from making, modifying or servicing a ticket.
- Meta's Muse and OpenAI's Dots can still search fares, but cannot buy.
- Sharing account credentials with a third-party assistant can expose sensitive information.
- Meta shares fell about 2 per cent to about $628 on Wednesday.
The contract, headed "revised November 11, 2026", adds an AI-agent definition to Rule 1 — any software that books, buys or manages a United product on its own — and a new Rule 6.J.6, barring "the use of AI Agents to make, modify or service a Ticket."
| AI agents on United | Status |
|---|---|
| Search United flights and show fares | Still allowed |
| Book or buy a ticket | Banned |
| Change or service a booking | Banned |
| Buy a seat or upgrade | Banned |
| Check in for a flight | Banned |
Can an AI Assistant Book a United Airlines Flight Now?
No. From November 11, an AI assistant may look up United flights and show fares, but it may not complete the purchase. The customer must finish the booking. Fares remain bookable through aggregators such as Kayak, Hopper and Google Flights, aviation analyst Henry Harteveldt said.
United said it is updating its booking, ticketing and distribution policies, and its Digital Trust Center states that the airline does not work with any third-party AI agents.
What Happens to United Flights Already Booked by an AI Agent?
Bookings an AI agent made before November 11 will not be cancelled, United said, but passengers should check recent trips were booked and ticketed correctly. From now on, a reservation made, modified or serviced by an unauthorised agent can be cancelled under Rule 5.H.
United gave three reasons. Sharing account credentials with a personal, third-party AI assistant can expose sensitive information, the airline said, and its actions may result in unintended purchases or use of MileagePlus miles. Automated check-in raises regulatory concerns, because travellers must verify in person that luggage holds no banned substances.
Why United Airlines Blocked AI Agents Ahead of the Holidays
United's chief executive, Scott Kirby, said at a Chicago event on Tuesday. "To be honest, I don't want to create another middleman," Kirby said. Harteveldt said the move suggests United wants to retain control over bookings, rather than add another intermediary alongside Google search and travel agencies.
The ban lands ahead of the Thanksgiving travel period, when US airports face their busiest days of the year, and as the air system heads into the holidays under strain from the federal shutdown, which has forced cuts at 40 airports.
United is not the first company to draw a line around agentic commerce. Amazon said on September 20 that it had cut Meta's Muse agent off from buying on Amazon.com, while Walmart has partnered with the same assistant and Expedia and Booking are working with OpenAI.
Frequently Asked Questions
Can ChatGPT or Meta's Muse book a United Airlines flight for me?
No. United bars unauthorised third-party AI agents, including Meta's Muse and OpenAI's Dots, from booking, changing or servicing its tickets. They can still search flights and show fares, but the customer must complete the purchase.
Will United cancel my flight if an AI agent booked it?
Not if it was made before November 11, 2026; United said those reservations will stand. Reservations made, modified or serviced by an AI agent after that date can be cancelled under Rule 5.H.
Can an AI assistant still search United flight prices?
Yes. United said AI tools may still look up flights and display fares and availability. The ban covers the transaction: booking, paying for, changing or servicing a ticket, or buying seats, upgrades and extras.
Which other companies have blocked AI agents from making purchases?
Amazon blocked Meta's Muse from buying on Amazon.com on September 20, 2026, and has also barred ChatGPT, Claude, Microsoft Copilot, Perplexity and Grok. Walmart has partnered with Muse, while Expedia and Booking are working with OpenAI.
Whether other US airlines follow is the next question. None has announced a similar ban, and United said it will keep evaluating the technology.
