TL;DR
United Airlines said Nov. 11 it is restricting unauthorized third-party AI agents from booking, changing or servicing tickets through its digital channels and intermediaries. Its revised contract allows the airline to cancel reservations made by agents, including when a person supervises the software; travelers can still use AI to search for flights but must make the purchase themselves.
United Airlines said on November 11 it is restricting unauthorized third-party AI agents from using its website, app and intermediary booking channels to buy or manage tickets. The airline’s revised contract of carriage lists agent use as a prohibited practice, including when a traveler supervises or approves the software’s actions, meaning customers must complete purchases themselves.
United’s announcement says the restrictions apply directly through its digital platforms and indirectly through travel agencies and aggregators. The revised contract, as quoted by travel industry publications, prohibits using an AI agent to make, modify or service a ticket, or to purchase a United product or service. Its definition covers software that takes autonomous or semi-autonomous action, including AI-enabled browsers and assistants connected through an intermediary.
The rule does not name particular products. The contract wording reported by View from the Wing, One Mile at a Time and PPC Land says supervision does not exempt a booking: the definition applies whether or not a passenger or another person supervises or approves the agent’s actions. The Wall Street Journal, as cited by View from the Wing, reported that AI may still be used to search for flights and present fares; the traveler must make the purchase.
Other provisions add consequences for bookings made or serviced by agents. As reported by PPC Land, United may cancel such reservations without notice. The contract’s remedies also include invalidating tickets, charging their full value, removing miles or ending MileagePlus membership. The contract does not specify whether the airline plans to apply each remedy to an AI-agent booking.
Why United Requires Travelers, Not AI Agents, to Book Flights
United’s revised contract restricts third-party AI agents from buying or managing tickets. Travelers can use AI to search, but must complete the purchase themselves.
Where United Draws the Line
The reported contract covers software acting autonomously or semi-autonomously, even when a person supervises or approves it.
- Find flight options
- Present fares
- Buy the ticket themselves
- Make changes or service tickets through permitted channels
Why United Says It Matters
The airline points to customer protection and control of the booking process.
Protect sensitive details
United says sharing credentials with third-party assistants can expose account information.
Keep checkout direct
CEO Scott Kirby cited not wanting to create another middleman.
What Travelers Should Know
The contract lists possible remedies, but does not explain how United will enforce them in each case.
- United may cancel reservations made or serviced by agents without notice.
- Other listed remedies include invalidating tickets, charging their full value, removing miles, or ending MileagePlus membership.
- The reported terms do not name specific AI products or clarify every search, form-filling, and checkout workflow.
Why United Keeps Checkout Human
The policy draws a line between AI as a search tool and AI acting as a booking intermediary. Travelers may be able to ask an assistant to find options, but United’s terms reserve the actual purchase and ticket management for a person using permitted channels. That distinction matters to customers who expect an agent to carry out a trip plan from search through checkout.
United cited risks including exposure of account credentials, unintended purchases or account changes, and potential conflicts with FAA and Department of Transportation rules. The airline specifically pointed to check-in acknowledgments about prohibited hazardous materials. The federal rule cited in the source requires airlines to present passengers with hazardous-material information at purchase and check-in, and requires acknowledgment when a passenger completes those steps without another person’s involvement. How that requirement applies to particular agent-assisted workflows is not settled by United’s announcement.
United’s chief executive, Scott Kirby, also gave a commercial reason, according to The Wall Street Journal: “To be honest, I don’t want to create another middleman.” That suggests the dispute is not only about safety or account protection; it also concerns who controls the customer relationship and booking process. The practical reach of the restriction may be limited for now: source material cited an Uber count of four agent-booked rides in a week with about 320 million trips and orders, but that figure is not a measure of airline bookings.

A New Rule for AI Booking
The revised contract adds AI agents to United’s existing list of prohibited practices, which includes fare-related conduct such as hidden-city and throwaway ticketing. United’s announcement described the policy as a restriction on unauthorized third-party agents, while the contract’s reported language covers a broad range of software and activities rather than naming specific services.
United is described by Skift as the first U.S. airline to state this kind of restriction explicitly. The broader travel industry is taking different approaches: the source material says Southwest and Expedia are working with ChatGPT, while other large companies, including Amazon and JPMorgan Chase, have restricted outside agents. Meta chief executive Mark Zuckerberg has called travel a “top use case” for the company’s Muse agent, according to Skift, reflecting why airline booking has become a test of how much control companies will give automated assistants.
The underlying contract text was not independently accessed by the source writer, who said united.com could not be loaded from the research setup. The wording in this report is therefore attributed to published quotations from the contract in View from the Wing, One Mile at a Time and PPC Land, which reproduced the text on November 11.
““United is taking steps to restrict access — directly within our digital platforms and indirectly via travel agencies and aggregators — to prohibit use by unauthorized, third-party personal AI agents or assistants.””

Enforcement and Legal Questions
It is not clear how often United will use the contract’s remedies against agent-made reservations, or how it will identify those bookings across agencies and aggregators. The terms list possible consequences, including cancellation and charges, but do not spell out an enforcement process or say which remedies would apply in a given case.
The source material does not identify specific AI services as approved or prohibited, and United’s definition covers categories rather than product names. It is also unclear how the airline will distinguish an agent that searches or fills in information from one that completes a purchase. The exact treatment of individual workflows will depend on implementation and any further guidance from United.
United cited FAA and DOT requirements, but the source material does not establish that all agent-assisted bookings violate those rules. A cited aviation regulation calls for passenger information and acknowledgment about hazardous materials; the application to different software arrangements remains a matter requiring clarification. The contract’s reported effective-date language also indicates that ticket terms are tied to the date of issuance, but details of how United will handle bookings around the revision were not provided.
How United Applies the Restriction
United has announced the restriction and revised its contract, but the next practical development will be how the policy appears in its website, app and distribution channels. Travelers using AI to plan a trip should check United’s current booking terms and complete ticket purchases themselves unless the airline provides different guidance.
Further clarification from United could explain how it identifies agent activity, which tools or intermediary arrangements it permits, and how it will handle reservations made before the contract revision. No timetable for additional guidance or changes to the policy was included in the source material.
Key Questions
Can I use AI to search for United flights?
Yes, according to reporting cited by View from the Wing. AI may search for flights and show fares, but the traveler must make the purchase rather than have an agent complete it.
Does human supervision make an AI-agent booking acceptable?
Not under the reported contract wording. Its definition covers autonomous or semi-autonomous actions whether or not a passenger or another person supervises or approves them.
What could happen if an AI agent books a ticket?
The contract says United may cancel reservations made, modified or serviced by AI agents without notice. Reported remedies also include invalidating tickets, charging their full value, removing miles or ending MileagePlus membership, though United has not said how it will apply each remedy.
Why did United restrict AI agents?
United cited account-security risks, unintended purchases or changes, and possible FAA and DOT rule issues. CEO Scott Kirby also said he did not want to create another middleman, according to The Wall Street Journal.
