United Airlines bans AI agents from booking flights on behalf of travelers

United Airlines is prohibiting third-party personal AI agents from booking flights for travelers and is revising its booking and ticketing rules to enforce the ban. The airline says agents may need access to sensitive data, including account and payment credentials, creating risks of unauthorized purchases, account changes, or misuse of MileagePlus miles. It also warns that AI-assisted tasks such as checking in could conflict with federal requirements - for example, rules that require passengers to confirm in person that their luggage contains no prohibited items. United plans to restrict agents’ access both on its own platforms and through travel agencies and booking aggregators.

Aviation analyst Henry Harteveldt argues that the policy also reflects United’s desire to retain control of the customer relationship and avoid the costs of a surge in automated flight searches. Airlines already contend with search engines, comparison sites, and online travel agencies, and AI tools could add another powerful intermediary. Other carriers are more open to AI discovery: Southwest, for instance, makes its flight inventory viewable to ChatGPT users. United fares will remain available through services such as Kayak, Hopper, and Google Flights, so travelers should still be able to compare prices, but AI agents will not make United fares easier to find or book.
