United Airlines Bars AI Agents From Logging In and Booking Flights

United Airlines is blocking AI digital assistants from logging into customer accounts and managing reservations. The carrier says the move protects customer information and helps it comply with regulations. The decision signals that major companies may restrict third-party AI agents acting on users' behalf.

Why it matters: Teams building or deploying AI agents that act inside consumer accounts now face access restrictions from large platforms, so they need to plan for data-security and compliance limits on agent access.
