ASSISTANT: Hi Donald.  How can I help you?

USER: I am going on a business trip to New York in November, and need to book a flight as soon as possible.

ASSISTANT: I can help you with that. First could I get your full first and last name?

ASSISTANT: And when in November would you like your flights to be?

USER: Ah, acutally, the return would be 11/02 and the departing date would be 10/31.

ASSISTANT: Where will you be flying out of and which airport do you plan to go to in New York?

USER: I would like to fly out of IAH and to LGA.

ASSISTANT: There's a Frontier flight for 200.  Would that work?

USER: That is perfect. Please book that for me. What is the flight number?

ASSISTANT: Flight 1004. Okay. Your flight has been booked.  Is there anything else that I can help you with today?

USER: No, that will do it. Thank you.
