United Just Told Your AI Assistant It Can’t Book Your Flight

United Airlines said on Wednesday, November 11, that it will stop third-party AI bots and personal AI assistants from booking tickets on behalf of travelers. AirlineGeeks described the decision as the first of its kind from a U.S. airline, arriving just as software agents that search, compare and pay for trips are moving from tech demos into everyday use. The restriction covers United’s own websites and apps, and the airline says it will also reach bookings that flow in indirectly through travel agencies and aggregators once its booking, ticketing and distribution policies are updated.

The airline framed the move around data privacy, security and regulatory compliance. United warned that customers who hand their account credentials to a personal AI assistant risk exposing sensitive information, and that an agent acting on its own could trigger purchases nobody intended, change account settings or spend MileagePlus miles. It also pointed to federal rules: some steps in the travel process, such as a passenger personally confirming that checked bags hold no prohibited items, are written with a human in mind, and United says automated actions could conflict with Federal Aviation Administration and Department of Transportation requirements.

United says its stance mirrors what banks and large retailers have done to limit automated agents, and it encouraged other companies to take similar steps. It plans to update its Digital Trust Center pages to spell out the restrictions, though the announcement did not give an effective date. The hotel side of the industry is wrestling with the same question. At a Skift event in New York the same day, MCR Hotels chief executive Tyler Morse said he would also like to keep AI booking agents away from his properties, while admitting he does not yet know how to enforce it.

For travelers, the practical advice is simple. If you have been experimenting with an AI assistant that logs in to airline accounts, do not give it your MileagePlus password, and expect United bookings made through such tools to be refused. Trips booked through an agency or online aggregator could also be affected as the new distribution rules take shape, so check that your reservation shows up correctly in United’s app. Booking directly yourself, or through a human agent, remains the reliable route while airlines, hotels and payment companies sort out who is accountable when software makes the purchase.
