User: This sounds good. It'll be a short trip so I'd like it to be Economy class. Can you help with purchasing tickets for the flight?
Assistant: So just to be sure, this flight originating in London will go to San Francisco. It is an American Airlines flight that departs next Monday and returns on March 12th. The onward flight leaves at 3:05 pm and return flight leaves at 7:05 am. It is for 4 passengers in the Economy class.
