United Airlines said Wednesday it is restricting unauthorized personal AI assistants from booking or managing tickets for travelers. The restriction applies through United’s website and app and through intermediaries such as travel agencies and aggregators, the carrier said in a company statement. It draws a distinction between software that helps travelers compare flights and software that acts for them once they choose one.
United cited the risk of exposing customer data and allowing unintended purchases, changes to reservations or use of frequent-flyer miles. The airline also said some actions, such as checking in a passenger, can require a traveler to acknowledge safety rules. The Journal report said United would still allow assistants to show its flights and prices. The change concerns who can complete the booking and manage it afterward.
What the policy covers
United updated its contract of carriage, the terms that govern transportation on the airline. An analysis of the revised terms by PPC Land said they prohibit AI agents from making or modifying tickets or buying services on a traveler’s behalf. That extends the restriction to purchases beyond the original fare, such as a seat assignment or an upgrade. The revised terms also cover software that takes actions after a traveler reviews or approves them.
The distinction is between a recommendation and a transaction. An assistant that presents a list of flights leaves the passenger to select and buy a ticket. An assistant that submits the purchase for the passenger acts on the reservation itself. The carrier is restricting the second activity when performed by an unauthorized third party, including when the tool reaches its inventory through another seller. That does not eliminate ordinary reservations made through established travel agencies.
What happens to existing reservations
United told Travel Weekly that it would honor bookings made on customers’ behalf by AI agents before Nov. 11. For subsequent reservations, the revised terms described by PPC Land add bookings made, changed or serviced by agents to the list of reservations United can cancel. The airline’s statement did not detail how it would notify a traveler who believes a new reservation was affected.
The carrier said it would update its Digital Trust Center with information about the restrictions, account protection and how to get help if an assistant takes an unintended action. Its own digital services remain available for passengers who want to make or change a booking themselves. A traveler using an outside tool will need to distinguish a displayed itinerary from a confirmed reservation, especially when a tool offers to finish checkout or make later changes.
Why check-in raises a different issue
Booking can involve payment credentials, loyalty balances and personal details. Check-in can also involve questions about what a person is carrying. The United statement pointed to a traveler’s acknowledgment of restrictions on dangerous goods as an example of a step the airline says should not be delegated to an automated assistant. United presented this as a potential regulatory risk. It did not cite a federal ban on the use of AI for comparing fares or report a regulatory finding against an individual booking.
The Federal Aviation Administration’s passenger guidance distinguishes rules for hazardous materials from the Transportation Security Administration’s screening rules. It also notes that some common products are treated differently depending on whether they are in checked or carry-on luggage. That distinction helps explain why United treats check-in as more than a confirmation that a passenger plans to travel: it can require information about what that passenger is bringing.
Analyst Henry Harteveldt told CBS News that the policy also limits the role of another intermediary between United and its customers. He said travelers would still be able to find United fares through conventional comparison sites. The airline’s stated reasons focus on data, safety and unauthorized actions; the analyst’s account points to the separate commercial question of who manages the sale and the relationship with the passenger.
Other airlines are weighing their options
JetBlue President Marty St. George told Reuters that he understood airlines’ caution about AI booking tools, but said they should pay attention to what their customers want. Travel Weekly reported that United’s restriction applies to unauthorized agents and that it had not yet made any authorization deals for AI bookings. That leaves room for a later agreement if a tool can meet the airline’s terms. There is no indication that carriers are adopting a uniform approach.
For travelers comparing tickets, the practical change is where the sale stops being a suggestion and becomes a commitment. Under United’s policy, viewing a fare through an assistant is different from instructing that assistant to spend money or change a ticket. The terms also apply beyond checkout, so an existing reservation and permission for an outside tool to manage it are separate questions. United says it will keep evaluating how those tools interact with its services as they evolve.
