United Airlines will restrict unauthorized AI agents from booking flights, citing security and federal rules. Delta, American and Southwest are letting agents book.

United Airlines said on Wednesday it will restrict unauthorized third-party AI agents from booking flights or managing reservations, both on its own platforms and via travel agencies and booking sites

Why United says it is doing this

United cited the risk of handing account credentials to an assistant: unintended purchases, account changes, misuse of MileagePlus miles, and possible violations of federal aviation rules. Check-in, for instance, requires a human to attest that bags hold no banned substances such as explosives, and an agent completing that step could violate them

United says agents can still surface its flights and fares to shoppers. What they cannot do is finish the purchase, and its systems can tell whether a reservation came from a person, a conventional agency or an automated assistant

There is a commercial motive too. Scott Kirby, United's chief executive, had already said as much the day before, at an event in Chicago: "To be honest, I don't want to create another middleman"

Rivals are inviting the agents in

United's rivals are taking the opposite path. Delta told reporters it allows authenticated AI assistants to complete bookings, with extra safeguards for sensitive transactions such as unaccompanied minors

. American told Fast Company some AI tools would be allowed to book, and Southwest launched a ChatGPT plug-in for finding trips earlier this year

The split runs across industries: Amazon blocked Meta's Muse agent while Walmart partnered with it, Expedia and Booking work with OpenAI, and eBay appeared to block agents

2

. Banks and retailers have reportedly made similar moves, United noted: JPMorgan Chase restricts agents, and Bank of America warned customers just last week not to share passwords with AI assistants

.

The behavior being blocked is currently rare. United itself says agent booking volume is low so far, and the wider numbers back that up: per Uber's own earnings call, agents accounted for 500 Uber Eats orders and four rides out of 320 million trips and deliveries in the week of Halloween

How the block would work, nobody knows

How United will actually enforce the restriction is undisclosed; The Register's suggestions, such as biometric confirmation or detecting automated browsing, are its own speculation, and United had not responded

. The announcement lands days before the holiday season, when many travelers are expected to lean on AI for trip planning

3

. Per Bloomberg's reporting via PCMag, it also follows an FTC inquiry opened last month into United and others over loyalty-based and AI-informed ticket pricing, though no causal link to the ban has been claimed

.

Per Engadget's reporting, the ban could limit the usefulness of new personal agents such as Meta's Muse and OpenAI's Dot. Muse previously leaked a user's address online, the kind of incident United wants no part of

. The mathematician Hannah Fry saw the risk up close when she handed her bank card to an AI agent for an experiment, as The Register recounts. The agent, nicknamed Cassandra, leaked passwords and made ill-considered purchases. "Don't let her incompetence fool you, because these things are getting better fast," Fry said of the experiment
