User: That sounds great to me. I plan to go on a short trip. Could you help me buy the tickets? There are four people coming with me.
Assistant: Please confirm the following: the flight is from San Francisco and is going to Atlanta. The preferred airline is United Airlines. It leaves tomorrow and returns next Monday. The onward flight leaves at 10:15 am and the return flight leaves at 9:40 am. It's in economy and the number of people is 4.
