Query: user: I need your help finding a one way flight. I only need one ticket and I would like it to be an economy ticket.
assistant: I can help you with that but first i'll need to know a few things. Where would you like to go, from which city would you like to depart from, and on which date would you like to trave?
user: I want to travel on the 4th to Chi-town from NYC.
assistant: Would you be interested in an American Airlines flight that takes off at 11:20 am with a ticket price of $180? The flight also has a layover.
user: That is fine. I'll keep it in mind but I want to check out the options for trains as well.
assistant: Would you still like to leave on March 4th?
user: No, on Tuesday next week.
