TL;DR
United Airlines revised its contract of carriage on November 11, 2026, to prohibit unauthorized third-party AI agents from booking, changing or servicing tickets and other products. The restriction applies even when a passenger supervises the agent; United says customers can still use AI to search for flights but must complete purchases themselves.
United Airlines has revised its contract of carriage to prohibit unauthorized third-party AI agents from making, changing or servicing tickets, including when a passenger supervises or approves the agent’s actions. The rule, dated November 11, 2026, could also cover purchases of other United products and services; passengers will have to complete those transactions themselves.
United’s announcement says it is restricting access to unauthorized personal AI agents and assistants both on its own website and app and indirectly through travel agencies and aggregators. The revised contract adds “the use of AI Agents to make, modify or service a Ticket” to its list of prohibited practices, according to text reproduced by travel-industry publications. United’s website could not be accessed by the source writer, so the wording was checked against copies published by View from the Wing, One Mile at a Time and PPC Land.
The contract defines an AI agent broadly as software or a service that takes autonomous or semi-autonomous action to search for, book, purchase, service or manage products offered by or through United. It says that applies “whether or not Passenger or another individual supervises or approves” the actions. The definition includes AI assistants on consumer platforms, AI-enabled browsers, standalone agents and third-party assistants using a travel agency or other intermediary’s connection. The text does not name particular products.
United says its concerns include account security, unintended purchases or account changes, and possible conflicts with FAA and Department of Transportation rules. The contract also says reservations made, modified or serviced by agents may be canceled without notice. It lists possible remedies such as invalidating tickets, charging their full value, deleting miles or ending MileagePlus membership. The reproduced text does not establish whether United plans to apply each remedy to agent bookings.
Want an AI agent to book United? You’ll have to do it yourself
United’s revised contract bars unauthorized third-party AI agents from booking or managing travel, even when a passenger supervises them. Travelers can still use AI to search, but must complete purchases themselves.
Where United draws the line
AI can help with flight discovery, but an unauthorized agent cannot complete or manage the transaction.
- Search for United flights
- Display fares
- Buy the ticket directly
- Make changes and service bookings themselves
The rule reaches broadly
The contract covers autonomous or semi-autonomous software, including when a passenger supervises or approves its actions.
Website and app
Unauthorized agents are restricted from acting through United’s digital services.
Agencies and aggregators
The restriction also addresses agents using intermediary connections.
What remains unclear
The contract states possible consequences, but the available material does not confirm how United will apply them.
- How the airline will identify unauthorized agents
- Which tools or integrations will be blocked
- Whether an approved connection path will be offered
- How remedies such as ticket invalidation or mileage consequences will be used
Who Controls the Airline Checkout
The rule draws a line between using AI to help plan a trip and letting software complete the transaction. According to The Wall Street Journal, as cited by View from the Wing, AI assistants may still search for United flights and display fares, but the traveler must buy the ticket directly. That distinction matters to customers who expect a single assistant to compare flights, apply preferences and finish a booking without handing the process back to them.
It also concerns the route through which airlines reach customers. United says its restrictions extend beyond its own platforms to agents operating through travel agencies and aggregators. The policy could limit how outside software interacts with United inventory, even when a traveler wants an agent to handle a routine purchase. How broadly the restriction will work in practice is not yet clear.
United’s chief executive, Scott Kirby, also gave a commercial rationale at an event in Chicago, according to the Journal: “To be honest, I don’t want to create another middleman.” That comment frames the dispute as more than a question about automation or safety. Airlines may also be concerned about who controls the customer relationship and booking channel as AI services try to take on the role of travel intermediary.

Airlines Face New AI Intermediaries
Personal AI agents are being promoted as tools that can turn a request—such as a destination, budget and seat preference—into a completed booking. Meta chief executive Mark Zuckerberg has described travel as a “top use case” for the company’s Muse agent, according to Skift. United’s rule addresses the point at which that assistance becomes an automated transaction on the airline’s systems.
Skift described United as the first U.S. airline to state such a restriction explicitly. The wider response from companies is mixed: the source reports that Amazon and JPMorgan Chase have blocked outside agents, while Southwest and Expedia are working with ChatGPT. Those examples do not establish a single industry policy; they show that companies are making different choices about third-party access.
Use of agents for purchases remains limited, according to the source. Uber counted four agent-booked rides in a week in which it handled about 320 million trips and orders. That is a reported count for a particular week, not evidence of a broader rate of adoption. It helps explain why United’s move is drawing attention now, before agent-mediated bookings become a routine channel.
““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.””
— United Airlines, in its November 11 announcement
Enforcement and Existing Tickets
Several practical questions remain open. United’s announcement does not spell out how it will identify an unauthorized agent, which specific tools or integrations will be blocked, or whether it will offer an approved way for AI services to connect. The contract names categories of software rather than individual products, so its application to particular assistants may depend on how they access and use United’s systems.
The source reports that the contract’s remedies include ticket invalidation, charges, mileage consequences and possible membership termination, but does not say which penalties United intends to use for agent activity. Nor does the available material establish how often the airline will cancel a reservation or how a passenger could resolve a dispute. The legal text’s provisions on cancellation and remedies are distinct from a confirmed account of enforcement in a particular case.
For tickets issued before the revision, PPC Land reports that the contract applies the terms in effect on the ticket’s issue date and reads that to mean earlier tickets remain under the earlier text. That is a publication’s interpretation of the contract, not a separately stated United ruling. The legal status of existing bookings and the precise reach of the policy have not been fully clarified.
Watch for Booking and Access Changes
Travelers booking United flights should expect to complete purchases themselves rather than rely on an unauthorized third-party agent to transact on their behalf. United says it is updating its booking, ticketing and distribution policies, but the announcement does not give a timetable for each platform change or describe a process for approving outside agents.
The next useful signs will be updates to United’s official contract and booking services, as well as any guidance on how the restriction applies to travel agencies, aggregators and existing reservations. Until the airline provides more detail, customers should treat the contract’s broad prohibition as the stated policy and avoid assuming that human supervision makes an agent booking permissible.
Key Questions
Can an AI assistant still help me find a United flight?
According to The Wall Street Journal as cited by View from the Wing, an assistant may still search for United flights and show fares. The traveler must complete the purchase rather than have an unauthorized agent make the booking.
Does supervising an AI agent make a booking allowed?
No. The revised contract’s definition covers autonomous or semi-autonomous actions whether or not a passenger supervises or approves them.
Does United name specific AI products in the rule?
The reproduced contract text does not name individual products. It describes categories, including platform assistants, AI-enabled browsers, standalone agents and third-party assistants using an intermediary’s connection.
Can United cancel a ticket booked by an AI agent?
The revised contract says reservations made, modified or serviced by AI agents may be canceled without notice. The available reporting does not establish how often United will use that provision or which other listed remedies it intends to apply.
What reason did United give for the restriction?
United cited risks involving account credentials, unintended transactions and potential regulatory issues. Chief executive Scott Kirby also raised a commercial concern, telling The Wall Street Journal he did not want to create another middleman.
