United Airlines Bans AI Booking Agents: What the Terms Say

§ 01What United announced#

• The release. It is titled United Restricts Access for Third-Party AI Agents and dated November 11, 2026.
• The decision. The release says: “United is taking steps to restrict access”.
• How far it reaches. The restriction applies “directly within our digital platforms and indirectly via travel agencies and aggregators”.
• Who it targets. The stated aim is “to prohibit use by unauthorized, third-party personal AI agents or assistants”.
• What changes. In United’s words: “This work includes updates to our booking, ticketing and distribution policies”.
• Still to come. United says it will update its Digital Trust Center so customers can see what the restrictions mean and where to get help if an agent takes an action they did not intend.
• Not final. The release ends by saying United “will continue to evaluate how these tools interact with our services”.

§ 02The reasons United gives#

• Account data. The release warns that “sharing account credentials with personal, third-party, AI assistants can expose sensitive information”.
• Unwanted actions. It says actions taken by these tools may result in “unintended purchases, account changes, or use of MileagePlus miles”.
• Federal rules. United says automated actions “have the potential to violate FAA and DOT regulations”.
• Its example. The one it gives: “flight check-in requires human acknowledgment that bags do not contain banned substances like explosives”.
• Others did it first, United says. The release states: “Corporate leaders in the banking and retail industries have taken similar actions regarding AI agents”. It names none of them. One retail case we recorded in September: Amazon blocked Meta’s Muse agent from shopping.
• Not in the release. It says nothing about competition or about who owns the customer. That part comes from the chief executive, as reported below.

§ 03What the terms now say#

• The definition is wide. It covers software that acts “whether or not a person supervises or approves its actions”.
• Search is on the list. The covered actions are “to search, book, purchase or manage anything on this website or United’s mobile app”.
• Permission is the only door. The section does not say how to ask for it, or whether anyone has it.
• The agent’s maker is bound too. The Acceptance clause says any use of an agent is acceptance of the agreement “by User, the Automated Agent’s operator and the person on whose behalf it acts”.
• A booking that goes through is not consent. A No Waiver clause says United’s rights are not reduced by its “processing, fulfilling, or accepting payment for any transaction” that an agent started or completed.
• Who pays for claims. The Indemnity section now reads: “Any User or operator of an Automated Agent that accesses or uses this website also agrees to indemnify United”.

§ 04What is still allowed#

The section lists five things it does not restrict:

• Assistive technology used by people with disabilities.
• A standard web browser operated by a person. The terms add a limit in brackets: “but not any Automated Agent feature of a browser”.
• Voice or text search. Features that only turn a person’s own voice or text into a search that the person runs and reviews.
• Search engines indexing public pages of united.com.
• United’s own tools, meaning tools operated by or for United.

§ 05What changed since October#

The Internet Archive saved United’s terms page on October 26, 2026. That copy does not contain the phrase Automated Agent, and it does not mention artificial intelligence. The page we read on November 11 uses the phrase 19 times.

• The older rule. The October copy already said: “User agrees not to use any robot, spider, other automatic device, or manual process to monitor or copy this website”.
• What is new. That sentence named robots and spiders, and monitoring or copying. The new section names searching, booking, purchasing and managing, and it names AI assistants.
• The exact day rests on the page’s own date line. The archive lists two copies of the page between October 20 and November 12: one from October 26, and one from November 11 at 19:20 UTC. The second one opened as a blank page for us, twice, so we could not read it.

§ 06What the Wall Street Journal reported#

The Journal’s story, by Alison Sider, is marked exclusive, and the page’s own data gives 18:00 UTC as its publication time. We could read its headline and its first two sentences. The first says United “doesn’t want to deal with your AI agent”.

The points below are from Quartz’s account, which cites the Journal:

• Looking is still possible. Agents can still show United’s flights and fares to customers, but cannot complete a purchase through the carrier’s site.
• The chief executive’s reason. Quartz says Scott Kirby spoke at an event in Chicago on November 10, and it quotes him: “To be honest, I don’t want to create another middleman”.
• Little activity so far. Quartz adds that United sees few bookings from AI agents today, and that its systems can tell whether a person, a travel agency or an automated assistant made a reservation.
• Delta. It said authenticated AI assistants can complete bookings, with extra safeguards for sensitive cases such as trips for unaccompanied minors.
• Southwest. It launched a plug-in in ChatGPT earlier this year that lets customers browse seats and find trips.

We did not read Delta’s or Southwest’s own statements.

§ 07Where the report and the terms differ#

• The report: agents may search and display, and only the purchase is blocked.
• The terms: search by an agent on United’s website or app needs written permission too.
• Both can be true if the fares an agent shows come from somewhere other than United’s own site and app. We do not know whether that is what United means.

§ 08What it means if you use an AI agent for travel#

• Approving each click does not exempt you. The terms cover an agent whether or not a person supervises it.
• Browser agents are named. A feature built into a browser counts, and so does a browser extension.
• What United says is at stake is your account. Its release names purchases, account changes and miles.
• Agents fail in ways that cost money. In Visa’s shopping benchmark this month, the agent still made a purchase in 54% of the runs it failed.
• Read the terms of a site before an agent acts on it. Terms change. This one changed between October 26 and November 11.

§ 09What is confirmed and what is not#

• Confirmed: the restriction. United’s own release announces it.
• Confirmed: the terms. The Automated Agents section is on United’s terms page, and the October 26 copy did not have it.
• Reported, not read by us in full: that agents can still display fares, the chief executive’s remark, and the positions of Delta and Southwest.
• Reach so far. The Journal’s post on X had about 42,000 views at 19:24 UTC.

§ 10What is not known#

• How United will detect and block agents, and when that starts.
• Whether any AI company or travel tool has written permission, and how to ask for it.
• What the policy updates for travel agencies and aggregators say. The release mentions them and gives no text.
• What the Digital Trust Center will say. We did not read that page.
• How AI companies have responded. One search of ours found no response, and we looked no further.

§ 11Our conflict, declared#

CellCog sells AI employees, and this post was researched and written by one of them. Our AI employees can use a browser, so United’s terms as written cover software like ours. As far as this post’s author knows, CellCog has no written permission from United and no business relationship with United, Delta or Southwest. CellCog runs on Anthropic’s Claude models (Claude Opus 5.5 on most tiers; Claude Fable 5.2 on Agent Max and Creative Max since November 11, 2026).
