The decision and the stated reasons
United Airlines will not allow personal AI assistants to book tickets on its system. The company cited privacy and regulatory concerns as reasons for the decision, according to The Verge, based on a Wall Street Journal article. The agents will still be able to show users United flights, but not complete the transaction on their behalf.
The cited reservations concern three areas. The first is the possible exposure of customer data. The second is the risk of unwanted purchases. The third concerns federal obligations on the information airlines must provide passengers: among them, attestation that baggage does not contain explosives. According to the company, an AI agent is unable to issue this attestation.
United also specified that it has so far not observed many attempts to book through AI agents. According to the Journal, the observation is consistent with what has been detected by other companies such as Doordash.
The context and implications for personal assistants
United's choice is part of a broader debate: companies are assessing whether to allow AI agents to conduct transactions on their sites. According to the material, eBay appeared to block agents' browsing, and several major banks had already imposed restrictions. United is therefore not an isolated case but an example of an emerging trend.
The most direct consequence concerns the usefulness of new AI-based personal assistants, such as Meta's Muse and OpenAI's Dots, cited in the material. If airline websites do not accept transactions performed by agents, the ability of these tools to complete practical tasks such as booking a flight is limited. United CEO Scott Kirby summarized the position during an event: he does not want to create another intermediary between the company and its customers.
United has left open the possibility of reviewing the decision in the future, depending on the progress of third-party agents. The company stated that it sees the opportunities these tools present, but wants first to establish protections for travelers, since allowing an agent to interact directly with a United account or booking would involve sensitive actions.
What remains to be verified
The material does not clarify what technical or contractual requirements United would intend to impose for any future authorization of agents, nor what security measures are already under study. It also does not specify whether the block applies to all third-party agents or only unauthorized ones, nor by what technical means it is applied. No figures are provided on AI agent traffic to United's systems. The actual scope of similar restrictions adopted by eBay and the cited banks is not detailed in the source.
