United Airlines Bans AI Agents From Booking Flights (Rule 6.J.6): What’s Allowed, Cancellation Risks & Airline Rules
United Airlines has written an explicit ban on personal AI booking agents into its Contract of Carriage. The change gives the airline legal authority to cancel bot-booked flights without notice. United Airlines bans AI agents booking flights effective November 11, 2026. Travelers need to understand what this means for their bookings and MileagePlus accounts.
The revised Contract of Carriage took effect on November 11, 2026. It updates Rule 1, Rule 5.F, Rule 5.H, Rule 6.J.6, and Rule 6.K. Rule 1 defines an AI Agent as any software or service that takes autonomous or semi-autonomous action. This includes AI assistants, AI agents, and AI-enabled browsers. The definition applies whether or not a passenger supervises or approves the actions. Rule 6.J.6 prohibits the use of AI Agents to make, modify, or service a ticket, and to purchase any service or product. Rule 5.H and Rule 5.F authorize United to cancel reservations made, modified, or serviced by AI Agents without notice. Rule 6.K allows ticket invalidation, MileagePlus mile forfeiture, and account termination. Bookings completed before November 11, 2026 are grandfathered and will be honored. Travelers can still use AI tools to search and compare flight prices. Only the transaction and servicing steps are prohibited.
If you booked a United flight through an AI agent before November 11, 2026, your ticket is safe and will be honored. Going forward, however, giving an AI browser or assistant your MileagePlus login to buy a ticket, swap a seat, or auto-check in violates Rule 6.J.6. This applies even if you manually click approve on the final screen. The reservation can be cancelled without notice under Rule 5.H and faces potential forfeiture of your MileagePlus miles under Rule 6.K. Note that using an AI agent after November 11 to modify or service a pre-existing booking could also trigger the rules.
United Airlines bans AI agents booking flights: FAA rules, Scott Kirby’s $2.1B warning & how Delta and Southwest differ
United cited FAA and DOT safety regulations as a reason for the ban. These rules require passengers to personally acknowledge hazardous-materials restrictions during check-in. An AI agent cannot make that acknowledgment on a traveler’s behalf.
CEO Scott Kirby explained the commercial motive in Chicago on November 10. He said, “To be honest, I don’t want to create another middleman.” United already spent $2.1 billion on distribution in 2025. Bot-defense data from Arkose Labs, dated October 20, 2026, shows that 97.7 percent of legitimate AI agent sessions carry no verified identity.
Rival airlines take different approaches. Southwest Airlines launched an official ChatGPT plugin with OpenAI and AWS that searches in chat and hands off checkout to Southwest.com. Delta Air Lines runs its own first-party Delta Concierge in the Fly Delta app and permits authenticated agents with safeguards. American Airlines continues to evaluate its position.
| Airline | AI Approach | Checkout Handling |
|---|---|---|
| United Airlines | Bans AI agents from transactions | No AI checkout allowed |
| Delta Air Lines | First-party Delta Concierge | Authenticated agents with safeguards |
| Southwest Airlines | Official ChatGPT plugin | Hands off to Southwest.com |
| American Airlines | Evaluating | Not yet announced |

Rule 1 defines AI Agents by autonomous or semi-autonomous action. Rule 6.J.6 covers only making, modifying, or servicing a ticket, and purchasing a service or product. Search and compare are not prohibited, so agent searches with human purchases remain allowed.
Can I still use AI to search for United Airlines flights under the new rule?
Yes. Under United Airlines’ revised Contract of Carriage effective November 11, 2026, travelers can still use AI assistants and chatbots to research destinations and compare United flight prices. However, Rule 6.J.6 strictly prohibits AI agents from purchasing tickets, selecting seats, buying upgrades, or modifying or checking in reservations, even if the passenger supervises every step.
