TL;DR
United Airlines said Nov. 11 that it is restricting unauthorized third-party AI agents on its digital platforms and through travel intermediaries. Its revised contract bars agents from making, changing or servicing tickets even when a traveler supervises or approves the action; the airline says agents may still search for flights, but travelers must complete purchases themselves.
United Airlines said on November 11, 2026, that it is restricting unauthorized third-party AI agents from using its website and app, as well as accessing the airline through travel agencies and aggregators. The airline’s revised contract of carriage prohibits agents from making, modifying or servicing tickets even when a passenger supervises or approves the software’s actions, putting a new limit on automated flight purchases.
United’s announcement says the restrictions apply across its digital platforms and indirect booking channels and form part of updates to its booking, ticketing and distribution policies. The revised contract, dated November 11, adds the use of AI agents to a list of prohibited practices. The text has been reproduced by travel publications including View from the Wing, One Mile at a Time and PPC Land; the source report said it could not independently load United’s website to check the contract directly.
As quoted by One Mile at a Time, the contract defines an AI agent broadly as software that takes autonomous or semi-autonomous action to search for, book, purchase, ticket or manage United products. It says the definition applies whether or not a passenger or another person supervises or approves the action. The listed categories include assistants built into consumer platforms, AI-enabled browsers and standalone agents, as well as third-party assistants that reach United through an intermediary. The contract does not name specific products.
The reported language also gives United the option to cancel reservations made, modified or serviced by AI agents without notice. Other contract provisions cited by PPC Land include remedies such as invalidating tickets, charging their full value, removing miles or ending MileagePlus membership. The source report says the contract does not specify whether United plans to apply those penalties to agent bookings. The Wall Street Journal, as cited by View from the Wing, reported that agents may still search for United flights and display fares; travelers would need to buy tickets themselves.
United draws a line for AI agents Search is allowed; booking is not
United’s revised terms prohibit unauthorized third-party AI agents from booking or managing tickets, even when travelers approve each step. Travelers must complete purchases themselves.
What travelers can delegate
The policy separates finding a flight from completing the transaction.
- Search for United flights
- Display fares
- Buy tickets themselves
- Make, change, or service tickets without an agent
Where the restriction applies
United says it covers unauthorized third-party agents across its booking routes.
United platforms
The restriction covers the airline’s website and app.
Travel intermediaries
It also covers access through travel agencies and aggregators.
What the contract says
Its definition covers autonomous or semi-autonomous software, whether or not a person supervises or approves it.
An agent may search and show fares.
The traveler completes the purchase themselves.
Agents may not make, modify, or service tickets.
Open enforcement questions
The available material leaves practical details unclear.
- United has not named specific AI products or explained how it will detect agent activity.
- The contract lists possible penalties, but the report does not establish that they have been applied to agent bookings.
- The report does not include an assessment from a regulator.
AI Flight Purchases Meet Airline Controls
The policy draws a practical line between using AI to find a flight and letting software complete the transaction. Travelers may be able to delegate research, but United’s terms say they cannot delegate ticket booking or management to a third-party agent, even if they remain involved in the process. That distinction matters to people building or using assistants designed to handle travel tasks from search through purchase.
United cites concerns about account credentials, unintended purchases and regulatory requirements. Its position also affects how travel agencies and aggregators can connect outside agents to airline inventory. The source report describes United as the first U.S. airline to state such a restriction explicitly, citing Skift. If other airlines adopt similar terms, agent developers may have to secure permission and technical access from each travel provider rather than rely on a general-purpose assistant to complete bookings.
There is also a commercial dimension. The source report says United CEO Scott Kirby told an event in Chicago, according to The Wall Street Journal, that he did not want the airline to create another middleman. That comment suggests the debate is not only about safe or compliant transactions: airlines may also seek to retain control over customer relationships and sales channels. At present, however, the report cites little evidence of widespread agent-led purchasing; it says Uber counted four agent-booked rides in a week with about 320 million trips and orders.

What United Changed in Its Contract
Personal AI agents are promoted as tools that can act on a user’s instructions, such as finding a suitable flight and completing a booking. Travel has been presented by some technology companies as a potential use case. The source report cites Meta CEO Mark Zuckerberg describing travel as a “top use case” for the company’s Muse agent. United’s new terms address the moment when such software moves from recommendations to acting on the airline’s services.
The reported contract revision adds AI agents to Rule 6.J.6, under “Prohibited Practices.” The clause covers using an agent to make, modify or service a ticket, or to buy a United product or service. The contract also reportedly applies to reservations made through an intermediary, rather than only to direct access to United’s app or website. Rule 3.E, as described by PPC Land, says the contract in effect when a ticket is issued applies to that ticket; the source report interprets this to mean tickets issued before November 11 fall under the previous wording.
United’s stated regulatory example concerns check-in acknowledgments about hazardous materials. The source report points to federal regulation 49 CFR 175.25, which requires airlines to provide passengers with information about forbidden hazardous materials and, in certain transactions completed without another person’s involvement, requires passenger acknowledgment that the information was presented. The report also cites criticism from Gary Leff of View from the Wing, who argued that the regulation does not require the customer to make the acknowledgment without technological assistance. That is a commentator’s interpretation, not a determination by a regulator.
““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 Regulatory Questions
Several practical details remain unresolved. United’s announcement and the quoted contract text do not identify particular AI products, explain how the airline will detect agent activity, or describe whether enforcement will differ between direct and intermediary bookings. The contract lists possible remedies, but the source material does not establish that United has used them against any traveler or agent.
The exact boundary between permitted assistance and prohibited action also needs clarification. The Wall Street Journal, as cited by View from the Wing, reported that flight search and fare display may remain possible, but the available material does not spell out how United will treat tools that fill in forms, retain passenger information or prepare a booking without submitting it.
United’s explanation references FAA and Department of Transportation rules, but no regulator’s assessment of the policy is included in the source material. The regulatory example and Leff’s response are competing descriptions of how passenger acknowledgments should work. It is not clear whether United consulted regulators or whether either agency has commented on the new terms.
How United Applies the New Rule
The immediate next step is for travelers and booking intermediaries to follow United’s revised terms when using its website, app or services reached through agencies and aggregators. People who want to use an AI assistant may be able to ask it to compare flights, but, according to the reporting cited here, should expect to complete a United purchase themselves unless the airline clarifies or authorizes another route.
Further details may come from United about how it identifies unauthorized agents, what it considers permissible search assistance and how it will handle bookings already made. Any clarification from regulators would help establish how the airline’s cited safety requirements relate to automated booking and check-in. The source material does not give a timetable for additional guidance or report a regulator’s response.
The wider test will be whether other airlines adopt similar restrictions or work with AI platforms on approved booking arrangements. For now, United’s revised contract sets a clear restriction for its own ticketing services, while the broader rules for AI-assisted travel remain unsettled.
Key Questions
Can an AI assistant still search for United flights?
Apparently, yes. The Wall Street Journal, as cited by View from the Wing, reported that an assistant may search for flights and show fares. The traveler would need to complete the purchase personally. United’s announcement does not provide a detailed list of allowed search functions.
Does traveler approval make an AI booking acceptable?
No, under the reported contract wording. The definition covers autonomous or semi-autonomous action whether or not a passenger or another person supervises or approves it.
What could happen to a ticket booked by an AI agent?
The contract reportedly allows United to cancel reservations made, modified or serviced by AI agents without notice. Other listed remedies include invalidating a ticket and charging its full value, but the source material does not establish whether United intends to apply those penalties to agent bookings.
Does the restriction name specific AI products?
No specific products are named in the reported contract text. It describes categories of software, including platform assistants, AI-enabled browsers, standalone agents and third-party assistants using an intermediary.
Does the rule apply to tickets bought before November 11?
The source report cites a contract provision saying the terms in effect on the date a ticket is issued apply to that ticket. It interprets this to mean tickets issued before November 11 fall under the earlier contract language; United’s treatment of existing bookings is not otherwise detailed in the material.
