While AI companies race to build agents that shop on our behalf, one of America's biggest airlines has shut the door. United Airlines now bars third-party AI agents from booking on its website and app.

The policy landed on Wednesday, Nov. 11, 2026, two days before OpenAI launched ChatGPT Wallet for agent-powered purchases.

This report draws on coverage by Skift, CBS News, PhocusWire and Business Travel News.

Quick answer: United Airlines bans third-party AI agents from making, modifying or servicing tickets and buying products on its website, app and through travel agencies, even when the customer supervises. AI assistants may still search flights and fares. United says sharing account logins with AI tools can expose data and trigger unwanted purchases.

What the New Rule Says

United revised its contract of carriage to bar the use of AI agents to make, modify or service a ticket, or to buy any service or product. The ban applies even when a customer supervises or approves what the software does.

It covers United's website and app as well as travel agencies and aggregators. Agencies cannot use third-party AI tools to book United travel for customers, though they may use their own tools with United's permission.

Why United Is Doing This

United says sharing account credentials with personal, third-party AI assistants can expose sensitive information and lead to unwanted purchases, account changes or spent MileagePlus miles.

Other reports cite privacy, security, and FAA and DOT rules. View from the Wing reported that CEO Scott Kirby does not want "another middleman" between the airline and its customers.

Other Airlines Take a Different Path

Southwest went the other way, letting users search its flights through a ChatGPT integration. Delta said it would weigh security and the customer experience before opening up to AI agents.

Analysts question enforcement: writing a ban into a contract does not mean United can always spot an AI-driven booking made through an intermediary like Expedia, though United says its systems can identify booking sources. The clash with launches like ChatGPT Wallet leaves an open question about who is responsible when an agent buys the wrong thing.
