TL;DR
United Airlines has added a contract rule prohibiting unauthorized third-party AI agents from booking, changing or servicing tickets and other products. The restriction applies even if a passenger supervises or approves the agent; United says customers can still use AI to search for flights but must complete purchases themselves.
United Airlines has barred unauthorized third-party AI agents from booking, changing or servicing tickets through its platforms or indirectly through travel agencies and aggregators, according to a company statement and revised contract terms published November 11. The rule applies even when a passenger supervises or approves the software, restricting a growing kind of automated travel service from completing purchases on United.
United’s press release says it is restricting access on its website and app, as well as through travel agencies and aggregators. Its revised contract of carriage adds “the use of AI Agents to make, modify or service a Ticket” and to purchase other products or services to a list of prohibited practices. The contract’s definition, as reproduced by travel-industry publications, covers software that takes autonomous or semi-autonomous action, whether or not a person supervises it.
The text names categories rather than specific products: assistants built into social, messaging and search platforms; AI-enabled browsers and standalone agents; and third-party assistants accessing United through an intermediary. According to The Wall Street Journal, as cited by View from the Wing, AI tools may still help users search for United flights and compare fares. The passenger must make the purchase directly rather than have an agent complete it.
United says the restriction is intended to address account security, unintended purchases and regulatory concerns. The company warned that sharing login credentials with outside assistants can expose sensitive information or lead to unwanted purchases, account changes or use of MileagePlus miles. It also said automated actions could create issues under FAA and Department of Transportation rules, citing passenger acknowledgment of restrictions on hazardous materials during check-in.
United draws a line on AI flight bookings
AI can help travelers search for United flights, but unauthorized third-party agents cannot book, change, or service tickets—even with passenger approval.
Search is allowed; checkout is not
Travelers must complete purchases themselves under United’s stated policy.
- Search United flights
- Compare fares
- Book or modify tickets
- Service tickets or buy other products
The restriction reaches intermediaries
United says it is restricting access across its own digital platforms and through third parties.
Website and app
Unauthorized agents cannot complete transactions through United’s digital platforms.
Agencies and aggregators
The policy also targets agent access routed through travel intermediaries.
Possible consequences and open questions
The contract lists remedies, but the published text does not say how often United will use them.
United may cancel reservations made, modified, or serviced by agents.
Listed remedies also include invalidating tickets, charging their full value, removing miles, or ending MileagePlus membership.
Detection methods, exceptions, and treatment of services that do not identify as agents remain unclear.
AI Can Search, but Not Purchase
The rule draws a firm boundary between AI as a flight-search tool and AI as an agent authorized to transact. For travelers, that means an assistant may help find an itinerary, but cannot handle the checkout or later ticket changes under United’s stated policy—even with the traveler’s permission. This limits the usefulness of services designed to carry out an entire trip-planning task from a single instruction.
It also affects how outside services can connect to airline systems. United says the restriction reaches access through travel agencies and aggregators, not only direct use of its site or app. That matters to companies developing automated booking tools and to customers who expect a single assistant to manage reservations across providers. The practical reach of the policy will depend on how United applies it and how intermediaries respond.
The rule includes potential consequences beyond blocking a checkout. The contract provisions, as quoted by PPC Land, allow United to cancel reservations made, modified or serviced by agents. Other remedies listed in the contract include invalidating tickets, charging their full value, removing miles or ending a MileagePlus membership. The published text does not establish that United plans to apply every remedy to agent bookings, or how it would identify them.

Airlines Draw Different AI Lines
Travel has been promoted as a promising use for personal AI agents because a booking involves several steps: finding a fare, choosing seats, entering passenger information and paying. Meta CEO Mark Zuckerberg has described travel as a “top use case” for the company’s Muse agent, according to Skift. United’s policy addresses that model at the point where an assistant moves from providing information to taking action on a customer’s behalf.
Skift described United as the first U.S. airline to state an explicit restriction of this kind. The source material also points to differing approaches elsewhere: Southwest and Expedia are working with ChatGPT, while Amazon and JPMorgan Chase have restricted outside agents. Those examples do not establish a common industry policy. Adoption of agent-led purchases appears limited so far: Uber reportedly counted four agent-booked rides in a week when it handled about 320 million trips and orders. That figure is a raw count; the source does not provide a baseline for calculating a comparative rate.
United’s contract version is dated November 11, 2026. The text of the relevant provisions was reported by View from the Wing, One Mile at a Time and PPC Land, which reproduced overlapping excerpts. United’s own statement confirms that it is updating its booking, ticketing and distribution policies, but the detailed contract language in the source material comes from those publications.
“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 Ticket Rules
It is not clear how United will detect agent activity, what technical steps it will use to restrict access, or how it will treat transactions made through services that do not identify themselves as agents. The contract lists possible remedies, but the published language does not say whether United intends to apply them in every case. The cited contract provision says the terms in effect on the ticket’s issue date apply; PPC Land reported that, on this basis, tickets issued before November 11 fall under the previous wording.
The scope of United’s regulatory argument is also disputed. The company says automated check-in actions could conflict with FAA and DOT requirements concerning hazardous materials. View from the Wing’s Gary Leff has questioned that rationale, arguing that the relevant rule does not require a passenger to have a human intermediary. The source material does not provide a regulator’s interpretation or a formal legal analysis resolving the disagreement.
United’s restriction concerns unauthorized third-party agents. The available material does not specify whether United will offer a company-approved agent, how any approved system would work, or whether the policy will change. It also does not establish how other airlines will respond.
Watch for Policy Enforcement
The immediate next step is for United to apply its revised booking, ticketing and distribution policies across its digital channels and third-party intermediaries. Travelers using AI for trip planning should expect to complete United purchases themselves unless the airline later announces an approved alternative. Customers with existing tickets should check the terms that applied when their tickets were issued if questions arise about changes or servicing.
Further clarity may come from United’s implementation, additional company guidance, or responses from travel agencies and AI-service providers. Any future claims about enforcement, exceptions or regulatory requirements should be distinguished from what is confirmed now: the contract text prohibits third-party AI agents from making, modifying or servicing bookings, including when a person supervises or approves their actions.
Key Questions
Can an AI assistant still help me find a United flight?
Yes. The Wall Street Journal, as cited by View from the Wing, reported that AI can still be used to search for United flights and fares. The passenger must make the purchase directly, rather than having the agent complete it.
Does passenger approval make an AI booking allowed?
No. The contract definition covers autonomous or semi-autonomous action whether or not a passenger supervises or approves it. The prohibition applies to unauthorized third-party agents making, modifying or servicing tickets.
Which AI products are prohibited?
The contract names categories of tools, including platform assistants, AI-enabled browsers, standalone agents and assistants that access United through travel intermediaries. It does not name specific products in the quoted text.
What could happen if an agent makes a reservation?
The contract says United may cancel reservations made, modified or serviced by AI agents. Other listed remedies include invalidating a ticket, charging its full value, removing miles or ending MileagePlus membership; the published text does not say whether United will use every remedy.
Does the policy apply to tickets bought before November 11, 2026?
PPC Land reported that United’s contract applies the version in effect on the date a ticket is issued, which would mean earlier tickets remain governed by the prior wording. The source material does not include a separate United explanation of how the rule will be applied to individual bookings.
