United is drawing a boundary around what personal AI assistants can do on its airline website: they may show flight options, but they may not book a ticket for a customer. The company says the restriction reflects concerns about privacy, purchases made without a customer’s intent and whether an agent can handle information airlines need travelers to receive and confirm.
Flight search is allowed; checkout is not
An AI agent can help a user find United flights, but the transaction must stop short of booking. That leaves the customer to complete the purchase directly, instead of handing the final step to an automated assistant.
The distinction matters because finding an option and buying it involve different levels of access. A search can present choices; a booking can affect an account, use personal information and commit a customer to a purchase. United says it wants protections in place before third-party agents interact directly with a United account or booking.
United’s concerns go beyond accidental purchases
The airline says an agent could expose customer information or make a purchase the customer did not intend. Those are risks of giving software permission to act on a person’s behalf, especially when the action involves a payment or travel reservation.
There is also a regulatory concern. The source article points to information airlines need to share with customers, including a traveler’s attestation that their bags do not contain explosives. United’s position is that an automated intermediary could complicate whether customers receive that information and provide the required confirmation.
That example shows why booking is not simply a matter of choosing a flight. Completing a transaction can include steps where the traveler must be informed and must respond. United is not allowing an agent to stand in for the customer at that point.
A wider question for AI assistants
United says it has not seen many people try to use AI agents to book flights, according to The Wall Street Journal. The article describes a similar pattern at other businesses: companies are weighing whether automated agents should be able to transact on their websites, and some are restricting access.
For people using personal AI assistants, the immediate limit is practical. An assistant can help locate a United itinerary, but it cannot take the process all the way through checkout. Users who want an agent to handle a purchase must still step in themselves for this airline.
United CEO Scott Kirby described his concern about adding another party to the process. “To be honest, I don’t want to create another middleman,” he said at an event on Tuesday, according to the Journal. That comment frames the issue as both a question of control and a question of who should sit between a traveler and an airline.
The policy could change as agents develop
United has left open the possibility that its approach could evolve. The company says it sees opportunities as third-party AI agents advance, while emphasizing that direct interaction with a customer account or booking can involve sensitive actions.
That leaves the door open, but makes safety protections the condition for any change. For now, AI travel tools may help with discovery on United, while the customer remains responsible for completing the booking and the steps attached to it.
The decision highlights a broader tension in personal AI: people may want assistants to handle more routine tasks, while businesses remain responsible for transactions and required customer interactions on their services. United’s current line is clear: flight information can be surfaced by an agent, but the purchase stays with the traveler.
