"Air Canada must honor refund policy invented by airline’s chatbot." The chatbot provided inaccurate information to a customer, encouraging the customer to make a purchase for bereavement travel, then use Air Canada's bereavement travel refund policy to receive a reimbursement. Unfortunately, Air Canada does not have such a policy. It was an AI hallucination. In legal trials, Air Canada argued that the client should have known better than to trust a chatbot. However, the final decision was that Air Canada is responsible for all the information on its website, "It makes no difference whether the information comes from a static page or a chatbot."
