United Airlines is restricting how travelers can use artificial intelligence to book or manage flights, warning that unauthorized AI assistants could expose sensitive data, trigger unintended purchases and create regulatory problems.
The airline announced the policy on Wednesday, Nov. 11, 2026. United said it is taking steps to block unauthorized third-party personal AI agents both on its digital platforms and indirectly through travel agencies and booking aggregators.
United Airlines Reveals Critical AI Booking Restrictions
According to the company, travelers who share account credentials with personal AI tools may put private information at risk. Automated assistants could also make changes to a customer’s account, purchase unwanted tickets or spend MileagePlus miles without the traveler fully realizing what happened.
United also pointed to federal aviation and transportation requirements that may require direct confirmation from the passenger. One example involves baggage declarations, including an acknowledgment that checked bags do not contain prohibited substances such as explosives.
The airline’s position is that an AI agent cannot legally make that confirmation on a traveler’s behalf. As a result, United said it will prohibit use by unauthorized third-party AI assistants and has updated its Digital Trust Center with guidance for customers.
United told Travel Weekly that it will honor reservations made with an AI agent before Nov. 11. However, the new policy raises questions about future bookings made through automated tools, especially when travelers may not know whether a website or agency is using AI behind the scenes.
What Travelers Could Risk When Using AI Agents
AI-powered travel assistants are designed to search flights, compare fares and complete purchases quickly. Supporters argue that these tools can save time and identify lower prices. However, consumer advocates say the convenience may not outweigh the potential risks.
- Incorrect travel dates or destinations
- Unintended purchases and account changes
- Use of MileagePlus miles without clear approval
- Confusion over restrictive or nonrefundable fares
- Possible cancellation of reservations made by unauthorized agents
Christopher Elliott, a consumer advocate and founder of The Elliott Report, told Yahoo Travel that AI agents can misread fare rules or book the wrong itinerary. When that happens, he said, airlines may treat the mistake as the passenger’s responsibility, making refunds difficult to secure.
Elliott also raised concerns about enforcement. United’s updated contract of carriage allows the airline to cancel a reservation made or changed by an AI agent. That could create a serious problem for travelers who unknowingly use an agency powered by such technology and discover at the airport that their seat is no longer available.
How Other Airlines Are Responding to AI Flight Bookings
United is not alone in reviewing the rapid growth of AI-assisted travel reservations, but major airlines are taking different approaches.
JetBlue president Marty St. George said on Nov. 11 that he knows customers are booking flights with AI agents. Reuters reported that he believes airlines should adapt to customer behavior, even if automated bookings create additional costs.
Delta’s policy allows customers to use third-party agents, but places responsibility for the agent’s actions on the traveler. The airline also reserves the right to block or reject automated transactions. In practical terms, a customer could be left to resolve the consequences if an AI tool books a nonrefundable flight to the wrong destination.
American Airlines said it monitors traffic on its website and app and can investigate, manage or block automated activity when necessary. Meanwhile, Southwest Airlines launched a ChatGPT plug-in in October that helps customers search for flights, although travelers must complete the booking themselves on Southwest’s website.
Consumer Advocates Recommend Human Help
Michelle Couch-Friedman, founder of Consumer Rescue, said travelers who do not want to make a reservation themselves should consider using a professional travel adviser. Human advisers typically carry errors and omissions insurance, while AI tools do not.
For now, travelers can still use AI to research destinations, compare schedules or build an itinerary. The safest approach is to review every detail personally and complete the final reservation directly through the airline or a trusted adviser.
