United says no to personal AI agents, even through travel agencies

United Airlines said on Wednesday it is banning personal AI agents from making flight reservations on behalf of travelers, according to a CBS News report on the carrier’s statement. The airline cites security risks and possible conflicts with federal rules.

What United says the ban covers

The restriction targets unauthorized, third-party personal AI agents or assistants. United said it will limit their access directly on its own digital platforms and indirectly through travel agencies and aggregators. The airline is updating its booking and ticketing policies to reflect the rule.

United gave two reasons. The first is credentials. To book, an agent needs a customer’s personal details and payment information, and the airline says that sharing account credentials with such tools can expose sensitive data. It also warned of unintended purchases, account changes, or use of MileagePlus miles.

The second is regulation. United said that using an agent to do something like check in for a flight could breach federal rules, including the requirement that travelers confirm in person that their bags contain no banned substances.

CBS notes that consumers already use assistants such as Meta’s Muse and OpenAI’s dots to research products, find deals and make purchases. The report does not say when the restriction takes effect, how United will detect agent traffic, or what penalties a customer might face.

Rivals are going the other way

Not every airline is shutting the door. Southwest has made its flight inventory viewable to ChatGPT users, who can reach the airline’s website through the app, according to the same report.

For travelers, the practical effect appears limited. Henry Harteveldt, an aviation analyst at Atmosphere Research Group, told CBS that United fares will stay bookable through aggregators such as Kayak, Hopper and Google Flights. In his words, “consumers shouldn’t find it any more difficult to find good fares on the airline.” He added that blocking bots will not make United fares easier to find either.

Harteveldt also read the move as a control play. In his view United does not want another intermediary, possibly a more powerful one, on top of Google search, metasearch sites and online travel agencies. He said flight searches cost airlines money, and that United likely wants to avoid the cost of a surge in AI bot searches. That is an analyst’s interpretation; United’s own stated reasons are security and compliance.

What to watch: Enforcement and the line between agent and aggregator

The wording leaves a hard question open. Aggregators and travel agencies are themselves third parties, and some already use automation. United’s text targets personal agents, but it does not define where an assistant ends and a legitimate booking tool begins. How the airline draws that line, and whether it publishes it in its terms, will show how far the ban reaches.

United’s position has a precedent in how it treats automated access. In 2013 it stopped ExpertFlyer from showing upgrade and award space, saying the site accessed united.com in an unauthorized way and used bandwidth other customers could use, according to Live and Let’s Fly. That earlier dispute concerned scraping tools rather than AI assistants, but the stated grounds of unauthorized access and load are similar.

The stance also fits what United executives have said about AI and sales. At the Aviation Festival Americas in June 2026, United’s vice president of sales strategy and effectiveness, Glenn Hollister, argued that AI’s impact on airline retailing depends on who ultimately controls it, according to Aviation Week. The new policy is a concrete example of an airline choosing to hold that control.

Three signals would confirm or undercut the picture: whether United publishes the revised policy text with a start date, whether other large carriers copy it or follow Southwest’s open approach, and whether AI assistant makers respond with airline-approved integrations. The source also does not establish how many bookings are currently made by personal agents, so the scale of the problem United describes is not independently verified.
