Hello, this is Donald.
Hi Donald.  How can I help you?
I am going on a business trip to New York in November, and need to book a flight as soon as possible.
I can help you with that. First could I get your full first and last name?
The full name is Donald Walker.
And when in November would you like your flights to be?
Ah, acutally, the return would be 11/02 and the departing date would be 10/31.
Where will you be flying out of and which airport do you plan to go to in New York?
I would like to fly out of IAH and to LGA.
There's a Frontier flight for 200.  Would that work?
That is perfect. Please book that for me. What is the flight number?
Flight 1004. Okay. Your flight has been booked.  Is there anything else that I can help you with today?
