TL;DR
United Airlines said Nov. 11 that it is restricting unauthorized third-party AI agents from using its digital platforms and, indirectly, travel agencies and aggregators. Its revised contract prohibits agents from booking, changing or servicing tickets, even if a person supervises them; travelers can still use AI to search for flights and complete the purchase themselves, according to reporting cited in the source material.
United Airlines said on November 11, 2026, that it is restricting unauthorized third-party AI agents from accessing its website and app and from acting indirectly through travel agencies and aggregators. A revised contract of carriage prohibits AI agents from making, modifying or servicing tickets, including when a passenger or another person supervises or approves the software’s actions.
United’s announcement says the restrictions cover access to its digital platforms and activity routed through travel agencies and aggregators. The airline said the changes include updates to its booking, ticketing and distribution policies. The contract language was published by travel-industry outlets including View from the Wing, One Mile at a Time and PPC Land; the source report says those outlets reproduced matching text, but its author could not independently load United’s website to check the document directly.
The contract’s revised section 6.J.6 places AI-agent use among prohibited practices. As quoted by One Mile at a Time, its definition covers software or services that take autonomous or semi-autonomous actions to search for, book, purchase, ticket, service or manage United products. It includes AI assistants on consumer platforms, AI-enabled browsers and standalone agents, as well as third-party assistants connecting through an intermediary. The wording does not name specific products.
The contract also says United may cancel reservations made, modified or serviced by AI agents without notice, according to the published excerpts. Other sections list possible remedies for prohibited practices, including invalidating tickets, charging their full value, removing miles or ending MileagePlus membership. The source material says the contract does not specify whether United intends to apply each remedy to agent bookings. The Wall Street Journal, as cited by View from the Wing, reported that customers may still use AI to find United flights and fares, but must complete the purchase themselves.
United’s AI Booking Ban Where the line is drawn
United’s revised contract bars unauthorized third-party AI agents from booking or servicing tickets. Travelers can still use AI to search, then complete the purchase themselves.
What agents can do
The reported policy separates flight research from completing a transaction.
- Use AI to find flights and compare fares.
- Complete the purchase yourself.
- Agents cannot book, change, or service tickets.
- Human supervision does not make agent actions permitted.
Where the rules apply
The restrictions cover direct platform access and activity routed through intermediaries.
United’s website and app
Unauthorized third-party agents are restricted from using the airline’s digital platforms.
Agencies and aggregators
The contract also addresses agent activity routed through travel agencies and aggregators.
Risks and open questions
The contract excerpts describe potential consequences, but leave enforcement details unclear.
United may cancel reservations made, changed, or serviced by AI agents without notice.
The contract lists invalidating tickets, charging their full value, removing miles, or ending MileagePlus membership; it does not say whether each applies to agent bookings.
The supplied reports do not explain how United will identify agent activity or handle bookings already in progress.
Why United says it acted
The airline cites account security, unintended actions, and compliance concerns.
- Sharing credentials with third-party assistants could expose sensitive information.
- Automated actions could trigger unintended purchases, account changes, or use of MileagePlus miles.
- United also points to passenger acknowledgment requirements for hazardous materials information.
A New Boundary for Flight Booking
The policy sets a clear boundary between AI-assisted flight search and AI-completed transactions. A traveler may be able to ask an assistant to compare options, but the reported rule prevents the agent from carrying out the purchase or subsequent ticket servicing. That distinction matters to people expecting an assistant to handle a trip from search through booking, and to companies building tools that act on a customer’s behalf.
For travelers, the contract’s stated cancellation provisions create a practical risk: an agent-made reservation could be canceled, and the contract lists potential financial and account-related remedies. The exact likelihood of enforcement is not stated in the cited material. United’s move also puts pressure on intermediaries and agent developers to determine what access remains permissible, particularly when an AI tool operates through a travel agency or aggregator rather than directly on United’s website.
United’s chief executive offered a commercial rationale as well as the airline’s stated security and compliance concerns. According to The Wall Street Journal, Scott Kirby said at an event in Chicago, “To be honest, I don’t want to create another middleman.” That comment points to a dispute over who controls the customer relationship and booking channel, beyond the technical question of whether an agent can complete a transaction.

How the Contract Sets the Limits
United’s press statement cited concerns about account credentials, unintended purchases and account changes, as well as possible conflicts with FAA and Department of Transportation rules. It said sharing credentials with third-party assistants could expose sensitive information and that automated actions could use MileagePlus miles or make changes without a customer intending them.
United also pointed to the requirement that passengers acknowledge information about hazardous materials at purchase or check-in. The source report cites federal regulation 49 CFR 175.25, which requires airlines to provide that information and, when a passenger completes a step without another person’s involvement, requires the passenger to acknowledge receiving it. Gary Leff of View from the Wing disputed the strength of United’s safety rationale, arguing that the regulation does not require the customer to perform the transaction without software assistance. That is an interpretation attributed to Leff, not a finding in the cited material.
The decision arrives as companies test personal agents for transactions. The source report says Meta chief executive Mark Zuckerberg described travel as a “top use case” for the company’s Muse agent, while other businesses have taken different approaches: it says Amazon and JPMorgan Chase have restricted outside agents, and Southwest and Expedia are working with ChatGPT. Those examples provide industry context, but do not establish how those services handle United bookings.
“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 statement
Enforcement and Passenger Exposure
Several practical points remain unclear. The published excerpts do not say how United will identify agent activity, distinguish an agent from other automated browsing, or enforce the restriction across travel agencies and aggregators. They also do not establish whether the airline will use every remedy listed in the contract, such as charging the full ticket value or terminating a MileagePlus account.
The source material reports that tickets issued before November 11 may remain governed by the earlier contract wording, citing a provision that applies the contract in effect on the ticket’s issue date. That reading is attributed to PPC Land and is not confirmed here by United. The reports also say AI may still be used to search and compare fares, but the exact boundary between permitted research and prohibited action is not fully detailed in the available excerpts. United has not provided, in the supplied material, a list of approved tools or an explanation of how it will handle bookings already in progress.
Watch for Booking Guidance
The immediate next step for travelers is to check United’s current contract and booking guidance before using an AI tool to interact with an existing reservation or make a purchase. Customers who want to use an assistant to compare flights can keep the agent at the search stage and complete any booking themselves, consistent with the account of the policy in The Wall Street Journal as cited by View from the Wing.
Further clarification from United could explain how the rule applies to agency bookings, which forms of automated assistance are permitted and what happens to reservations made before the revision. Until that guidance appears, the published contract language and United’s statement are the available basis for understanding the restriction. The source material provides no date for a further announcement or enforcement milestone.
Key Questions
Can an AI assistant still search for United flights?
Yes, according to reporting cited in the source material. The Wall Street Journal, as cited by View from the Wing, reported that an AI assistant may search for United flights and show fares, but the customer must buy the ticket themselves. The exact limits on other forms of automated assistance are not fully described in the published excerpts.
Does human supervision make an AI booking allowed?
No, not under the quoted contract definition. The language covers autonomous or semi-autonomous actions “whether or not Passenger or another individual supervises or approves” them. That means supervision alone does not remove an action from the stated prohibition.
What could United do with a reservation made by an AI agent?
The contract language quoted by travel-industry outlets says United may cancel reservations made, modified or serviced by AI agents without notice. Other listed remedies include invalidating tickets, charging their full value, removing miles or ending MileagePlus membership. The supplied material does not establish that United will apply every remedy to agent bookings.
Does the restriction name specific AI products?
No specific products are named in the contract wording described in the source material. The definition instead describes types of software and services, including platform assistants, AI-enabled browsers, standalone agents and third-party assistants connecting through intermediaries.
Are tickets purchased before November 11 affected?
The source report says the contract applies the terms in effect on the date a ticket is issued and cites PPC Land’s reading that tickets issued before November 11, 2026, fall under the earlier text. United’s application of that provision to past or ongoing agent bookings is not confirmed in the supplied material.
