Can an AI Agent Book Your United Flight? Not Anymore
United's Nov 11 contract change lets it cancel bookings an AI agent made or changed, even with your approval, and lists penalties up to deleting miles.

As of November 12, 2026. We read United's contract of carriage and United's November 11 news release that day.
Can you still use an AI assistant to book a United flight? Not to book it, change it or pay for anything. On November 11, 2026, United revised its contract of carriage, the legal terms every United ticket is sold under. United now says it "will cancel without notice" any reservation "made, modified or serviced by AI Agents," and it lists "the use of AI Agents to make, modify or service a Ticket, and/or to purchase any service or product" as a banned practice. The contract applies this "whether or not" you supervise or approve what the AI does.
What United counts as an "AI Agent"
United's new definition is broad. In its words, an AI Agent is "any software or service, including but not limited to an AI assistant, AI agent or AI-enabled browser that takes autonomous or semi-autonomous action, whether or not Passenger or another individual supervises or approves its actions, to discover, search for, book, purchase, ticket, service or manage any product or service offered by or through United."
It names three kinds:
- AI assistants built into social media, messaging, search or other consumer apps
- AI-enabled browsers and standalone AI agents
- Any third-party AI assistant that reaches United through a tool, app or connection a travel agency or other intermediary provides
The definition mentions searching, but the two rules below are written about booking, changing, servicing and buying. The contract doesn't say how United will treat an AI tool that only searches.
What United can do about it
It can cancel the booking. United's reservation rule says it "will cancel without notice" a list of "improper reservations." The last item on that list is new: "reservations made, modified or serviced by AI Agents."
It treats AI booking like other banned ticketing practices. Rule 6 now lists "the use of AI Agents to make, modify or service a Ticket, and/or to purchase any service or product" next to practices like fraud and gaming fare rules. For breaking those rules, United says it may act "without notice to the passenger" and "in its sole discretion." The remedies it lists include:
- Invalidating the ticket
- Canceling the rest of the itinerary
- Refusing to board you, or banning you permanently, unless the fare difference is paid before boarding
- Charging you the difference between the fare paid and the lowest fare for the trip you actually took
- Deleting MileagePlus miles, revoking elite status or ending your MileagePlus membership
Why United says it made the change
United's November 11 release, titled "United Restricts Access for Third-Party AI Agents," gives two reasons. The first is accounts: "sharing account credentials with personal, third-party, AI assistants can expose sensitive information, and actions taken by these tools may result in unintended purchases, account changes, or use of MileagePlus miles." The second is safety rules: United says automated actions "have the potential to violate FAA and DOT regulations," and gives check-in as the example, because it "requires human acknowledgment that bags do not contain banned substances like explosives."
United says it is restricting access "directly within our digital platforms and indirectly via travel agencies and aggregators," and that it will update its Digital Trust Center to explain what the restrictions mean and where to get help "if an agent takes an unintended action."
What this means if you book United with miles or cash
- Booking it yourself is unchanged. The rule is about software acting for you, not about booking on united.com or in the United app. If you're new to booking with miles, our step-by-step points guide walks through finding and booking award seats yourself.
- A human travel agent is not an AI Agent. An AI assistant that reaches United through a travel agency's tool is, under the third kind on United's list.
- If an AI tool booked or changed a United trip for you, open the reservation in the United app and check that it's still there and still says what you expect.
- Your MileagePlus login is part of the risk United names. Its release lists "use of MileagePlus miles" among the things an AI assistant with your credentials can do.
- This is United's contract. We read only United's terms. Other airlines' contracts may say something different.
