TL;DR
United Airlines said Nov. 11 it is restricting unauthorized third-party AI agents from using its digital platforms and other booking channels to make or manage purchases. Its revised contract prohibits those actions even when a person supervises the agent; passengers can still use AI to search for flights and fares, then book themselves, according to reporting cited in the source material.
United Airlines said on Nov. 11, 2026, that it is restricting unauthorized third-party AI agents from using its website, app and indirect booking channels to make, change or service tickets. The revised contract of carriage prohibits agents from taking those actions even when a passenger supervises or approves them, putting a contractual limit on software that can search for and purchase travel for a user.
United’s announcement says the restrictions apply directly on its digital platforms and indirectly through travel agencies and aggregators. The carrier said the changes include updates to its booking, ticketing and distribution policies. It did not name particular AI products in the reported contract language; the restriction is written to cover types of software and services rather than a specific brand.
As quoted by travel-industry sites View from the Wing, One Mile at a Time and PPC Land, the contract’s Rule 6.J.6 prohibits using AI agents to make, modify or service a ticket, or to purchase a United product or service. The definition includes AI assistants, AI-enabled browsers and other software that takes autonomous or semi-autonomous action. It also covers tools that reach United through an intermediary such as a travel agency.
The rule does not appear to bar every use of AI in flight planning. The Wall Street Journal, as cited by View from the Wing, reported that an assistant may still search for United flights and display fares, while the traveler completes the purchase. The source material does not include a direct United statement spelling out that distinction, so the practical limits may depend on how the tools access United and what actions they perform.
Why United Is Restricting AI Flight Bookings
United’s revised contract bars unauthorized third-party AI agents from booking or managing tickets, even with passenger approval. Travelers can still use AI to search for flights and fares, then book themselves.
Where United draws the line
The contract focuses on what software does, rather than naming particular products.
- Search for United flights
- Display fares for comparison
- Make or change a ticket
- Purchase or service a ticket
A broad rule across booking channels
The restriction applies on United’s platforms and through intermediaries.
Website and app
Unauthorized agents may not use United’s digital platforms to manage purchases.
Agencies and aggregators
The reported rule also covers agents reaching United through booking intermediaries.
Why the airline says it matters
United cites credential exposure and unintended purchases or MileagePlus account changes.
CEO Scott Kirby said he did not want to create another middleman between the airline and passengers.
United says automated actions could conflict with passenger acknowledgments; that interpretation is disputed in cited coverage.
What remains unclear
- How United will identify agent use or enforce the rule
- Whether specific tools can be approved
- How the restriction applies when travelers approve each action
- When updated policies will be rolled out
Who Controls the Airline Checkout
The policy draws a line between AI as a search tool and AI acting as a booking intermediary. That matters to travelers who want an assistant to compare options and complete a purchase, but it also protects the airline’s direct relationship with customers and its control over ticketing, account access and add-on services.
United’s CEO, Scott Kirby, gave a commercial explanation at an event in Chicago, according to the Wall Street Journal: “To be honest, I don’t want to create another middleman.” The remark suggests the restriction is not only about security or compliance. If an agent books on a customer’s behalf, it may become another layer between the airline and the passenger, potentially influencing how fares and services are presented and who controls the transaction.
The immediate scale of the issue remains uncertain. The source material says agent-led purchases are rare so far, citing Uber’s report of four agent-booked rides in a week that included about 320 million trips and orders. That is a figure from another industry, not a measure of airline bookings. Still, the United policy could shape expectations before automated purchasing becomes common in travel.

The Contract Sets a Broad Boundary
United’s revised contract places AI agents in a section listing prohibited practices, alongside fare practices such as hidden-city and throwaway ticketing. The text reportedly defines an agent by what it does—taking autonomous or semi-autonomous action to search, book, purchase, ticket or manage products—rather than by a particular company or application. That breadth means the rule could cover future tools as well as those currently available.
United cited account credentials, unintended purchases and changes to MileagePlus accounts or miles as reasons for the policy. It also argued automated actions could conflict with FAA and Department of Transportation requirements, giving check-in acknowledgments about prohibited hazardous materials as an example. The source material notes that federal rules require passengers to be presented with safety information and to acknowledge it in certain cases; it also relays criticism from Gary Leff of View from the Wing, who disputed United’s interpretation. The legal question is not settled by the material provided.
Other businesses have taken different approaches to outside AI agents. The source reports that Amazon and JPMorgan Chase have blocked external agents, while Southwest and Expedia are working with ChatGPT. Skift described United as the first U.S. airline to state this kind of restriction explicitly. That characterization is attributed to Skift, not an independent survey of every airline’s policies.
““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 announcement
Enforcement and Existing Tickets
The reported contract language gives United several possible remedies for prohibited activity, including cancelling reservations made, modified or serviced by agents. Other provisions reportedly allow invalidating tickets, charging their full value, removing miles or ending MileagePlus membership. PPC Land noted that the contract does not say whether United plans to apply those penalties to agent bookings, and United has not specified how enforcement will work.
The source material says the contract applies the terms in force on the date a ticket is issued, and PPC Land’s reading is that tickets issued before Nov. 11 fall under the previous wording. That interpretation has not been independently confirmed here. It is also unclear how United will identify agent use, how the rule applies when a traveler approves each action, or whether particular third-party tools will receive permission.
United’s claim that automated actions could violate FAA and DOT rules is also disputed in the cited coverage. The material describes the relevant passenger acknowledgment requirement but does not establish that every agent-assisted booking or check-in would violate it. The airline has not publicly detailed the legal analysis behind that claim.
How United Applies the Restriction
The next practical test will be how United applies the contract across its website, app and indirect distribution partners. Travelers and travel companies will need clearer guidance on whether an AI tool may search, fill in passenger details or assist with account tasks before a human completes the transaction.
United’s announcement says it is updating booking, ticketing and distribution policies, but the source material gives no rollout schedule or enforcement timetable. The airline has not identified specific blocked services, described a process for approving agents, or said whether it will publish further guidance. Until it does, the clearest reported boundary is that unauthorized agents may not make, modify or service tickets, while customers can complete bookings themselves.
Key Questions
Can I still use AI to find United flights?
According to The Wall Street Journal as cited by View from the Wing, an AI assistant may still search for United flights and show fares. The traveler must complete the purchase themselves; United has not provided a detailed public guide to every allowed search function.
Does a human approving the booking make it allowed?
The contract language quoted by travel-industry sites says the definition covers autonomous or semi-autonomous action whether or not a passenger supervises or approves it. Approval alone therefore does not appear to exempt an agent from the restriction.
Which AI products are banned?
The reported contract does not name specific products. It describes categories including AI assistants, AI-enabled browsers and third-party tools that access United through an intermediary. How the wording applies to individual services has not been clarified.
Could United cancel an AI-booked ticket?
The reported contract allows United to cancel reservations made, modified or serviced by AI agents. Other possible penalties are listed, but United has not said whether or how it intends to use them against agent bookings.
Why did United impose the restriction?
United cited risks involving account credentials, unintended purchases and changes to MileagePlus accounts, as well as possible conflicts with FAA and DOT rules. CEO Scott Kirby also cited a commercial concern, saying he did not want another middleman between the airline and its customers.
