United Airlines says it will restrict access for AI agents that book flights and manage reservations on users' behalf. The airline cites cybersecurity risks and possible conflicts with federal aviation rules.

United Airlines said it will restrict AI agents and autonomous assistants from booking flights and managing reservations for users. The airline described the move as a response to cybersecurity risk and to potential conflicts with federal regulations. It is the latest large American company to block such tools from its systems.

The airline warned that sharing account credentials with third-party AI assistants can expose sensitive information. It also said actions taken by these tools could lead to unintended purchases, account changes, or use of MileagePlus miles. United added that some federal aviation rules require a human to complete steps such as check-in and acknowledging that bags contain no banned substances.

United said the restrictions will apply directly in its digital platforms and indirectly through travel agencies and aggregators. The company said it is updating its booking, ticketing and distribution policies. The announcement follows a warning from banks, including Bank of America, urging customers not to share passwords with AI assistants.

## Why it matters if you build agents

Agents that book or change United reservations through its own site, travel agencies or aggregators may now be blocked, so builds that depend on those flows need a fallback. Developers should check how their travel integrations handle access refusals. Credential-sharing designs that log in on a user's behalf face the same scrutiny from airlines and banks.
