United Airlines banned third-party artificial intelligence agents from making flight reservations on Wednesday citing security risks and potential federal rule violations.
The policy update places direct limits on automated bots attempting to handle travel arrangements. The carrier prohibits unauthorized AI assistants from buying tickets, changing itineraries, or managing flights across its website, mobile app, and indirect channels such as travel agencies and ticket aggregators.
United Blocks Automated Booking Tools
“sharing account credentials with personal, third-party, AI assistants can expose sensitive information, and actions taken by these tools may result in unintended purchases, account changes, or use of MileagePlus miles,” United warned. Actions taken by these assistants may result in unintended purchases, account changes, or use of MileagePlus miles without passenger authorization.
Consumers use artificial intelligence agents such as Meta’s Muse and OpenAI’s dots to complete tasks. Flight check-in requires passengers to personally acknowledge that luggage lacks prohibited materials like explosives, an obligation that automated bots cannot legally fulfill on a traveler’s behalf.
Industry Rivals Weigh Bot Rules
The restriction points to a commercial dispute over customer relationships and distribution spending.
Harteveldt said that United fares will continue to remain bookable through flight aggregators such as Hopper, Kayak, and Google Flights. Consumers should not find it any more difficult to find good fares.
Competing carriers are adopting varied strategies toward automated tools.

Carriers Enforce Contract Penalties
The newly revised Contract of Carriage gives United grounds to cancel unauthorized reservations without notice. Penalties include ticket invalidation and travel restrictions. The airline confirmed it will honor any reservations completed by automated tools before November 11.
Travelers can use artificial intelligence systems to research destinations and compare flight prices.
