United Airlines Bars Unauthorized AI Agents From Booking and Check-In, and Extends the Ban to Travel Agencies

United Airlines has drawn a line between an AI agent that plans a trip and one that buys it, in what Reuters called one of the airline industry's clearest signs of resistance to booking agents. The carrier said on November 11 it would restrict AI bots' access to its digital platforms, citing data security, Reuters reported, and its new policy page goes further than a website block: it covers travel agencies and aggregators too.

What United is restricting#

United's page says that if a third-party AI agent, bot, browser extension or browser feature "searches, books, buys, manages or collects information" on united.com or the United app without permission, it is unauthorized. Customers can still use AI to research and plan trips as long as the tool does not touch United's site or app, and assistive technology for customers with disabilities is not affected.

The restriction also reaches indirect channels. Travel agencies and booking platforms cannot use third-party AI agents to search for, book or manage United travel on direct or indirect channels, and may only use their own AI tools with United's permission, the airline says. Reuters reported that United will update its booking, ticketing and distribution policies to do this.

United gives two kinds of reason. One is account risk: handing an agent MileagePlus credentials could expose personal information or lead to purchases, account changes or use of miles the customer did not approve. The other is regulatory: check-in requires a human acknowledgement that bags contain no banned items such as explosives, and automating it "could result in you missing important safety content" and could breach FAA and DOT rules, the airline says.

Bookings made by agents before November 11 will not be cancelled. United says it does not yet work with any third-party AI agents but wants "standardized, secure technology integrations" with authorization and accountability protections.

The industry split#

Reuters noted that companies are taking different approaches: Amazon has blocked Meta's agent Muse while Walmart has partnered with it, and Expedia and Booking work with OpenAI. That Walmart partnership sits alongside the retailer's agent gateway, which publishes per-agent profiles, spending limits and an MCP gateway for the agents it authorizes.

JetBlue president Marty St. George said on November 11 that he can see why airlines are wary, and worries intermediaries could eventually seek payment for directing bookings, Reuters reported. "We should be responsive to what customers want," he said at the Skift Commerce Summit.

Limits#

• United has not said how it will detect agents or enforce the agency rule, or how often agents have booked with it so far.
• Both news accounts are Reuters reports; the airline's own page is the primary source for the policy terms.
