United Airlines Bans AI Agents From Booking Flights
United Airlines bans AI agents from booking flights, checking in passengers or changing customer accounts, becoming the first major United States carrier to draw a formal line against automated booking tools.
The airline announced the policy on November 11, citing concerns about passenger privacy, unauthorised purchases and compliance with federal aviation regulations. The restrictions apply to AI agents using United’s website and mobile app, as well as those operating through travel agencies and booking platforms.
Why United Airlines bans AI agents
United said letting AI assistants into customer accounts could expose sensitive personal and financial information. These tools usually need account logins and payment details to book flights or manage travel, and the airline warned they could make purchases, change reservations or spend MileagePlus miles without the customer’s approval.
The ban is written into United’s revised Contract of Carriage. Rule 6.J.6 lists AI agents making, changing or servicing a ticket, or buying any service or product, among prohibited practices. Rule 5.H lets United cancel reservations made or managed by AI agents without notice.
The ban applies even if a passenger watches the agent or approves its actions. Bookings completed before November 11 will not be cancelled, but United advises travellers to check they were ticketed correctly.
The check-in problem
United also raised a regulatory concern about automated check-in. Under United States aviation security rules, passengers must personally acknowledge that checked baggage contains no prohibited materials, including explosives, and an AI agent completing that step could bypass the required acknowledgement.
United cited Federal Aviation Administration and Department of Transportation rules. Under the hazardous materials rule, airlines must tell passengers about banned items when they buy a ticket and check in, and passengers must confirm they received that information.
The airline will update its Digital Trust Center to explain the restrictions and guide passengers concerned about account security. It also plans to explain how customers can seek help if an AI agent performs an unintended action. AI assistants are already taking on business tasks in other sectors, and OpenAI has brought business profiles to ChatGPT, while researchers at MIT have even tested AI agents in a desert island simulation.
A first for a major US airline
United is the first major US carrier to announce such restrictions formally. Delta Air Lines was reported last month to be blocking similar tools, but has made no formal announcement. The Wall Street Journal first reported United’s move.
There are also commercial reasons behind the decision. United chief executive Scott Kirby said at an event in Chicago that he did not want to create another middleman between the airline and its customers. Aviation analyst Henry Harteveldt of Atmosphere Research Group told CBS News that flight searches cost airlines money, so a surge in automated searches by AI agents could add expense without producing bookings. Airlines are also under scrutiny over how they use data and AI in pricing, and the Federal Trade Commission recently ordered Delta, United and JetBlue to explain how they set fares and whether personal data plays a role.
What travellers can still do
The ban does not cut travellers off from United flights through normal booking channels. According to Harteveldt, passengers will still be able to find and book United flights through established services such as Google Flights, Kayak and Hopper. The restrictions target unauthorised AI agents acting on a customer’s behalf, not the booking platforms themselves. Travellers can also still use AI tools to research and plan trips, as long as those tools do not access United’s website or app to transact. Travel agencies and booking platforms must obtain United’s express written consent before using AI agents to service its flights, or risk losing their authorisation to issue United tickets.
United said companies in banking and retail have introduced similar restrictions on third-party AI agents. The airline added that it does not currently work with any third-party AI agents, but wants to build standardised, secure integrations with privacy and accountability protections first. It will keep reviewing how personal AI assistants interact with its services as the technology develops.
For travellers in Pakistan booking United flights, the message is simple: an AI assistant can help plan the trip, but the booking must be completed by the passenger through United or an approved channel. In Pakistan, AI is seen as an opportunity rather than a threat, and foreign airlines here have faced questions over a $2.4 billion outflow.
