United Airlines Plans to Ban Personal AI Assistants from Booking System; Meta Shares Dip Slightly. According to Jinse Finance, on November 12th, United Airlines (UAL.O) planned to ban personal AI assistants from accessing its system for booking tickets, sparking market concern about restrictions on the commercial application of AI agents. As AI assistants such as Muse from Meta Platforms (META.O) and Dots from OpenAI gradually take on routine tasks like booking tickets, banks, retailers, and other businesses are reassessing how to manage system access permissions for such agents. Following the announcement, Meta's stock price reversed its earlier slight rise and fell, dropping approximately 0.2% during the session.
