user: I need help finding a one-way flight.

system: I'd be happy to help. Where do you want to go?

user: I want to go to Philadelphia on the 1st of this month.

system: Ok, and where do you want to fly from?

user: I'll be leaving from Washington.

system: I was able to find 3 flights that match your requirements. American Airlines has a flight leaving at 8 am with 1 stop. The cost would be $138.

user: Which airport does that flight leave from and when would I arrive in Philadelphia?

system: The flight leaves from Dulles International Airport and will arrive at your destination at 11:36 am.

user: That might work.

system: Would you like me to book you a ticket for that flight?

user: No thanks. Can you look for one flexible bus ticket there that leaves on the 8th?

system: Yes, there are 8 buses available. The first leaves at 7:10 am and costs $50 for a flexible ticket.

user: Ok, can you buy that bus ticket for me?

system: Please confirm you would like to purchase 1 flexible bus ticket from Washington to Philadelphia, leaving on March 8th at 7:10 am.

user: Yes, buy the ticket. What station do I leave from and arrive at?

user: Thats. I don't need anything else.

system: Have a safe trip.
