TL;DR
United Airlines said on November 11, 2026, that it is restricting unauthorized third-party AI agents on its digital platforms and through travel agencies and aggregators. Its revised contract prohibits agents from booking, changing or servicing tickets even when a passenger supervises or approves the actions; passengers can still use AI to search for flights, but must complete purchases themselves.
United Airlines said on November 11, 2026, that it is restricting unauthorized third-party AI agents from using its digital platforms and accessing its services through travel agencies and aggregators. The airline’s revised contract prohibits such agents from making, modifying or servicing tickets even when a passenger supervises or approves their actions, placing limits on AI tools that can carry out travel purchases for customers.
United’s announcement said the restrictions apply both directly on its website and app and indirectly through travel agencies and aggregators. The revised contract of carriage, as quoted by travel-industry publications that reproduced its text, adds the “use of AI Agents to make, modify or service a Ticket” to its list of prohibited practices. United’s announcement did not name particular AI products.
The contract’s reported definition covers software or services that take autonomous or semi-autonomous action to search for, book, purchase, ticket, service or manage products offered by or through United. It includes AI assistants, AI-enabled browsers and third-party tools connecting through an intermediary. The wording says the restriction applies whether or not a passenger or another person supervises or approves the software’s actions.
According to The Wall Street Journal, as cited by View from the Wing, an AI assistant may still search for United flights and present fares; the customer must complete the purchase themselves. United says it is concerned that sharing account credentials could expose sensitive information and that automated actions could cause unintended purchases, account changes or use of MileagePlus miles. The airline also cited possible conflicts with FAA and Department of Transportation rules.
AI booking on United Approval is not enough
United allows AI to search for flights, but its revised contract bars unauthorized agents from booking or managing tickets—even when a passenger approves.
Where the line falls
The policy separates finding a flight from carrying out a transaction.
- Search United flights
- Present fares
- Complete the purchase
- Book, change, or manage tickets directly
Approval does not change the rule
United’s reported contract language applies whether or not a passenger supervises or approves the agent.
An AI assistant may find flights and present fares.
The passenger completes the purchase themselves.
Ticket changes and servicing must use an authorized process.
Why United cites the restriction
The airline points to risks for both travelers and operations.
Sensitive information
Sharing account credentials could expose personal information.
Unintended changes
Automated actions could trigger purchases, account changes, or use of MileagePlus miles.
Rules and acknowledgments
United says automated actions could conflict with FAA and DOT rules.
A divided travel market
Companies are taking different approaches to outside AI agents.
| Example | Reported approach |
|---|---|
| United | Explicitly restricts unauthorized agents from transactions |
| Amazon and JPMorgan Chase | Have blocked outside agents |
| Southwest and Expedia | Working with ChatGPT |
Why Human Approval Does Not Change the Rule
The policy draws a boundary between AI-assisted flight research and AI carrying out a transaction. A customer may use an assistant to compare options, according to the Journal’s reporting, but cannot make the agent the actor that books, changes or manages a United ticket. That distinction matters to travelers who expect an agent to handle an entire trip after receiving instructions and approval.
It also places responsibility on customers using third-party tools to understand what those tools do. United’s contract reportedly gives the airline authority to cancel reservations made, modified or serviced by agents without notice. Another clause says the airline is not liable for certain damages when it cancels under that rule, according to PPC Land. The contract’s remedies section also lists actions such as invalidating tickets, charging their full value, removing miles or terminating MileagePlus membership; the published text does not establish whether United plans to apply each remedy to agent bookings.
United’s chief executive, Scott Kirby, gave a commercial reason as well as the operational concerns. Speaking at an event in Chicago, he said, according to The Wall Street Journal, “To be honest, I don’t want to create another middleman.” The policy could preserve the airline’s direct relationship with customers and control over ticket sales, while limiting the ability of outside agents to transact on its behalf.

United’s Rule Enters a Divided Travel Market
Personal AI agents are promoted as tools that can act on a user’s behalf, rather than only answer questions. In travel, the proposed use is to search for a flight, apply a traveler’s budget and preferences, book a ticket and help with later steps. Skift reported that Meta chief executive Mark Zuckerberg described travel as a “top use case” for the company’s Muse agent.
United’s move is part of a mixed response by companies to outside agents. Skift reported that United is the first U.S. airline to state such a restriction explicitly. The source material also says Amazon and JPMorgan Chase have blocked outside agents, while Southwest and Expedia are working with ChatGPT. Those examples reflect different approaches; they do not establish that the companies’ policies or products are equivalent to United’s.
Use of agents for purchases appears limited so far. The source material cites Uber as having counted four agent-booked rides during a week in which it handled about 320 million trips and orders. Those figures describe that reported week, not a general adoption rate or a comparison with earlier periods. The scale of current use of AI agents for airline purchases remains unclear.
““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.””
— United Airlines
Enforcement and Existing Tickets Remain Unclear
The published contract text identifies possible remedies, but the source material does not say how United will detect agent use or whether it intends to apply every listed penalty to those bookings. It also remains unclear how the rule will operate when an agent accesses United through an agency or aggregator, a route the airline explicitly included in its announcement.
United said automated actions could create FAA and DOT compliance risks, including around the passenger acknowledgment required for hazardous-material information. The source material cites federal requirements concerning presentation of that information at purchase and check-in, but does not establish that the regulation categorically prohibits an agent from performing either step. Gary Leff of View from the Wing criticized United’s safety rationale as “weak”; that is his assessment, not a government finding.
According to PPC Land’s account of the contract, Rule 3.E applies the contract in effect on the date a ticket is issued, suggesting tickets issued before November 11 fall under the earlier wording. The source material presents this as the publication’s reading. United has not, in the material provided, explained how it will treat existing reservations, agent-assisted bookings already made, or disputed cases where a human approved an action.
How United Applies the New Terms
United has said the changes cover its booking, ticketing and distribution policies, but the available announcement does not provide a detailed enforcement schedule or explain what notice customers will receive before a reservation is canceled. The practical next development is likely to be clarification from the airline or travel intermediaries about which tools are blocked and how customers can complete bookings that began with an AI search.
Travelers using AI tools should distinguish between an assistant that finds flight options and one that logs into an account or completes a transaction. Under the reported contract language, human approval does not make an agent booking permissible. Until United provides more detail, customers who want to buy or manage a ticket should do those steps directly through United or a travel provider using an authorized process.
Key Questions
What has United prohibited?
United’s revised contract, as quoted by travel publications, prohibits unauthorized AI agents from making, modifying or servicing tickets and from purchasing products or services offered by or through the airline.
Does a passenger’s approval make an AI booking acceptable?
Not under the reported wording. Its definition covers autonomous or semi-autonomous actions whether or not a passenger or another person supervises or approves them.
Can an AI assistant still help find a United flight?
According to The Wall Street Journal, as cited by View from the Wing, an assistant may search for flights and show fares. The customer must complete the purchase themselves.
Can United cancel a ticket booked by an AI agent?
The contract reportedly allows United to cancel reservations made, modified or serviced by AI agents without notice. The source material does not clarify how frequently the airline will use that power or how it will identify agent activity.
Does the rule apply to tickets bought before November 11?
PPC Land reports that the contract applies according to the version in force when a ticket is issued, which would point to earlier terms for tickets issued before November 11. United has not provided a specific explanation of how it will handle existing agent-assisted reservations in the material available.
