United Airlines blocks personal AI agents from booking flights

Restricting automated bookings

United Airlines announced on Wednesday that it is restricting access to its booking systems for unauthorized third-party personal AI agents. These new rules will apply across the airline's digital platforms as well as through various travel agencies and aggregators. The company is updating its core policies regarding ticketing, distribution, and general booking procedures.

The airline's decision comes as personal AI assistants become more capable of performing complex tasks for users. While these tools can search for information, United wants to ensure that the final transaction remains under human control. The carrier stated that it will continue to monitor how these personal AI assistants interact with its services as the technology evolves.

United is currently seeing very little booking activity from AI agents. However, the airline's back-end systems are already equipped to distinguish between a human traveler, a traditional travel agency, and an automated assistant. This technical distinction allows the company to enforce these boundaries consistently across its various sales channels.

Security and data protection

A primary driver for these restrictions is the protection of sensitive customer information. United warned that sharing account credentials with personal AI assistants can expose private data to potential risks. The airline wants to prevent unauthorized access to personal profiles and travel history.

Beyond data privacy, the company is concerned about the consequences of automated actions. If an AI agent has the power to finalize a purchase, it could result in unintended transactions. This includes making unauthorized purchases, changing account details, or spending a customer's MileagePlus miles without their explicit consent.

United is urging other industries to consider similar steps to keep accounts secure. The airline noted that banking and retail companies have already taken similar actions against personal AI agents. These measures are intended to create a safer environment for consumers who are increasingly using AI to manage their daily lives.

Aviation safety and regulations

The airline also highlighted significant regulatory hurdles that automated agents cannot currently navigate. Tasks carried out automatically by AI tools might break rules set by the Federal Aviation Administration (FAA) and the Department of Transportation (DOT). These regulations are designed to ensure the safety of every flight and passenger.

One specific example provided by United involves the flight check-in process. Current regulations require a human to acknowledge that their bags do not contain banned substances, such as explosives. An AI agent cannot legally provide this human acknowledgment, making it ineligible to complete the check-in process independently.

By blocking these agents from the final booking step, United ensures that all legal requirements are met. The airline is prioritizing compliance with federal safety standards over the convenience of fully automated travel planning. This creates a clear boundary between what an AI can help research and what a human must execute.

The competitive landscape

United is not the only airline looking at how to handle AI, but it is taking a more restrictive path than some competitors. As reported by The Wall Street Journal, other U.S. airlines have not yet publicly announced similar bans on personal AI agents. This creates a fragmented landscape for how different carriers interact with new technology.

Delta Air Lines has taken a different approach by allowing authenticated AI assistants to complete bookings. Delta has implemented specific safeguards for sensitive transactions, such as making travel arrangements for unaccompanied minors. This suggests that Delta is betting on a system of permissions rather than a total block on automated actions.

Southwest Airlines has also integrated with AI, but in a limited capacity. Earlier this year, the carrier rolled out a plugin for ChatGPT that allows customers to browse available seats and locate trips. However, this tool is designed for information gathering rather than completing the actual purchase of a ticket.

What this means for travelers

For the average traveler, these changes mean that while AI can be a powerful research tool, it will not be a personal concierge that can book a trip from start to finish. Customers will still be able to use AI agents to surface available flights and compare different fares across the web. The AI can do the heavy lifting of finding the best options based on a user's preferences.

Once a user selects a flight, they will need to move to the carrier's site to finalize the purchase. United is updating its Digital Trust Center to help customers understand these new restrictions. The center will provide information on how to protect personal accounts and where to seek help if an AI agent performs an unintended action.

United's CEO Scott Kirby expressed his stance on the role of technology in the travel industry during a recent event in Chicago. "To be honest, I don't want to create another middleman," Kirby said, according to The Wall Street Journal. This suggests the airline's goal is to keep the relationship between the carrier and the customer direct, even as AI becomes a common tool for planning.
