United Airlines Restricts AI Agents for Flight Bookings to Enhance Security

United Airlines Restricts AI Agents for Flight Bookings

United Airlines has announced new policies to block unauthorized third-party artificial intelligence (AI) agents from booking or managing flights on behalf of customers. This move aims to enhance account security and prevent unintended transactions. The airline’s updated ticketing and distribution policies will restrict these AI tools from accessing its website and app for various services.

The airline stated that these AI agents can book and manage trips with minimal human oversight. This policy update affects how AI tools can interact with United’s digital platforms and booking systems. While AI can still be used for research, the final purchase and management of flights must be handled by a human.

AI Agents Prohibited from Transactions

Under the updated rules, AI agents are specifically prohibited from making, changing, or servicing flight tickets. They also cannot purchase other products or services related to travel, such as seat upgrades or baggage. United reserves the right to cancel any reservations made or managed by unauthorized agents without prior notice.

This restriction applies to various forms of AI, including standalone agents, AI assistants, and browsers with AI capabilities. Even if a passenger is supervising the AI agent, the restriction still applies. The core issue is the unauthorized access and management of customer accounts and transactions by these automated tools.

Scope of the Restrictions

The new rules extend beyond simple ticket purchases. They cover any alterations or servicing of a reservation after the initial transaction. This also applies when an AI agent operates through an intermediary, such as a travel agency or an online aggregator. United has not yet authorized any AI booking agreements with third parties.

Travel agencies and platforms are also barred from using third-party AI agents to search for, purchase, or manage United flights. If these entities wish to use their own internal AI systems for such purposes, they require explicit permission from United Airlines. This distinction allows for the use of digital tools for comparison shopping, as long as the customer makes the final decision and completes the transaction themselves.

Human-Led Transactions Remain an Option

United Airlines emphasizes that human-led transactions are still fully available through various channels. Travelers can choose to buy tickets directly from United’s website or app. Travel advisors can also make reservations through a Global Distribution System (GDS).

Customers can use platforms like Google Flights or ChatGPT for research, but they must complete the transaction personally. Services like Kayak, Hopper, and Google Flights can display United fares, but an unauthorized AI agent cannot finalize the purchase for the customer. AI-driven flight research is permitted, but United’s website terms require written permission for any automated access to its site or app.

Security and Safety Concerns Drive Policy

United Airlines cites account security and passenger safety as primary reasons for these restrictions. The airline explained that sharing account credentials with personal, third-party AI assistants can expose sensitive information. Actions taken by these tools could lead to unintended purchases, unauthorized account changes, or the misuse of MileagePlus loyalty program miles.

Additionally, United points to potential compliance issues with Federal Aviation Administration (FAA) and Department of Transportation regulations. For example, airlines must provide passengers with information about dangerous goods at the time of purchase and check-in, and obtain their acknowledgment. While federal regulations do not explicitly prohibit AI transactions, United’s policy aims to ensure these requirements are met through secure, human-verified processes. The airline plans to add guidance to its Digital Trust Center regarding account protection and assistance for unintended actions.

Industry Trends and Future Evaluation

United’s CEO, Scott Kirby, has previously expressed reservations about increasing intermediaries in the travel industry. Aviation analysts also note that AI agents could become another layer between consumers and airlines, potentially increasing the cost of flight searches if automated tools generate numerous queries.

Other travel and technology companies are exploring different approaches to AI integration. Southwest, for instance, displays flights in platforms like ChatGPT for customers to book themselves. Many airlines, including Delta, American, and Southwest, use AI in other operational areas like customer service and pricing. In other sectors, companies like eBay have also moved to block agent browsing, and major banks have restricted AI agents due to security concerns. United states it will continue to evaluate AI assistants as they develop and has described its policy as the first of its kind from a major U.S. carrier.

Honoring Past Reservations

United Airlines will honor reservations that were made by AI agents prior to the policy’s announcement. However, the airline advises passengers with such bookings to review their trip details carefully for any potential errors. For future travel, United encourages passengers to use human-led channels or digital platforms where they maintain control over the decision-making and transaction process.
