United Airlines is moving to block unauthorized third-party AI agents from accessing its digital platforms, including through travel agencies and aggregators. The airline announced changes to its booking, ticketing and distribution policies on November 11, 2026. Source
The restrictions start before the checkout button. United’s FAQ says an AI agent, bot, browser extension or browser feature is unauthorized if it searches, books, buys, manages or collects information for you on united.com or the United app without the airline’s permission. Source
“Just because you’ve given access to AI assistants doesn’t mean United will permit an AI assistant to transact with United,” the airline says in its FAQ. Source
A travel agency isn’t a back entrance, either. United says agencies and booking platforms cannot use unauthorized third-party AI agents to search for, book or manage United travel through direct or indirect channels. Agencies need United’s permission to use those tools; ordinary travel-agency bookings aren’t banned. Source
Why United says it’s drawing the line
United says sharing account credentials with personal AI assistants could expose sensitive information or lead to unintended purchases, account changes or spending of MileagePlus miles. The announcement doesn’t identify a specific breach or unintended purchase. Source
The airline also warns that check-in by an AI agent could violate Federal Aviation Administration and Department of Transportation regulations, citing the requirement for a human to acknowledge that bags don’t contain prohibited substances such as explosives. That example concerns check-in, a separate step from buying a ticket. Source
What travelers can still do
AI-assisted trip planning remains allowed, provided the tool doesn’t access United’s website or app. United recommends sticking to general information rather than sharing private details, and says travelers should review AI-generated text and perform searches themselves on its platforms. A list of restaurants in Rome is still on the menu. Your MileagePlus password should stay out of the prompt. Assistive technology for customers with disabilities is unaffected. Source
United says AI-agent bookings made before November 11, 2026 will not be canceled. It recommends checking recent travel plans to ensure they were booked and ticketed correctly. That assurance does not extend to bookings made on November 11 or later. Source
United also recommends immediately changing your password if you’ve shared MileagePlus login information with a third-party AI agent. Source
The airline’s FAQ says it doesn’t yet work with any third-party AI agents and wants secure integrations with privacy, authorization and accountability protections. Its announcement doesn’t explain how the restrictions will be enforced or give a completion date. Source Source
