United Airlines has banned artificial intelligence (AI) agents from booking flights on behalf of travelers, citing security risks and potential violations of federal rules. The airline is concerned that sharing personal and payment information with AI agents, such as Meta's Muse and OpenAI's dots, could expose sensitive data and lead to unintended purchases or account changes. Additionally, United notes that using AI agents to complete tasks like checking in for a flight could violate federal regulations, including those requiring in-person verification of luggage contents. As a result, the airline is restricting access to its digital platforms to prevent AI agents from making bookings and other transactions on behalf of customers.
