United Airlines moves to block AI agents from its platform over security concerns

www.cnbc.com · November 11, 2026 · 20:02

United Airlines said on Wednesday it would restrict AI bots' access to its ⁠digital platforms, citing data security, in the latest pushback ​against AI agents ​increasingly capable ​of planning and booking trips for travelers.

Companies across industries ⁠are ‌taking divergent approaches to the ⁠rapid rise of AI agents capable of carrying out tasks on behalf of users — some restricting access ‌to protect their platforms, others embracing partnerships.

Amazon has blocked Meta's AI ​agent Muse, while Walmart has partnered with it.

Meanwhile, online travel firms such as Expedia and Booking are working ⁠with ChatGPT-parent OpenAI.

United warned that sharing ‌account credentials with third-party AI ‌assistants could expose sensitive information and lead to unintended purchases, account modifications or the unauthorized use ⁠of frequent-flyer miles.

It also said automated ⁠AI tools performing actions like flight ⁠check-in — which requires human acknowledgment for prohibited items such as explosives — could ​create regulatory risks.

The ‌carrier said it would take steps to restrict access both directly through its digital platforms and indirectly through travel agencies and aggregators, including ​updates to its booking, ticketing ‌and distribution policies.
