United banned AI agents from buying tickets. It's right about why.

On 11 November United changed its Contract of Carriage. Rule 6.J.6 now forbids "the use of AI Agents to make, modify or service a Ticket, and/or to purchase any service or product", and Rule 5.H lets United cancel any reservation an agent touched. The definition is wide: any AI assistant, agent or AI-enabled browser, "whether or not Passenger or another individual supervises or approves its actions".

It's easy to read this as an airline protecting its margins, and that's part of it: Scott Kirby is reported as saying he doesn't want another middleman. But read United's reasons and they're the same three I keep finding when websites turn agents away:

The agent spends money the person didn't mean to. A ticket, a seat, an upgrade, miles.
The agent holds the person's login, on someone else's servers.
Nobody confirms what a person has to confirm. For an airline that's literal: federal rules assume a passenger says, at check-in, that their bag holds nothing dangerous.

None of those is something an agent needs to do to be useful. Most of what people ask an assistant about a flight is a look-up: is it on time, which gate, what does Newark to San Francisco cost on the 8th.

So that's what I built for United, in the tool I'm making. It has two look-ups: flight status and flight search. On 13 November it reported UA 857 San Francisco to Shanghai on time from gate G7, and a nonstop from Newark to San Francisco on 8 December from $179. Both run in the person's own Chrome, not on a server with their password. It has no action on United at all, not even one that waits for a yes, because United says a yes doesn't count. When the person wants the flight, they buy it on united.com.

United's rule doesn't forbid that. It forbids an agent making, changing or servicing a ticket, or buying anything, and searching and showing fares stays open.

What I think United gets wrong is the same thing most of these bans get wrong: they can't tell a careful agent from a careless one, so they ban the category. There's still no agreed way for a personal agent to say "I'm acting for this signed-in customer, I only read, and they'll buy it themselves." Until there is, the honest move for anyone building agents is to stay on the side of the line the business drew, and to say plainly which side that is.

I'm building this as Bowser, a waiting list for now: https://www.bowser.live/locked-out?ref=united-article
