Hello.

Hi.  How can I help you?
assistant
I am planning to meet my childhood friend located in Houston, so please check a flight ticket from IAD to MCO.
user
Okay.  What name will this flight be under?
assistant
I would like to book this ticket under name Joseph Nelson.
user
What days do you intend to travel, Mr. Nelson?
assistant
I want to start my trip on 01/29 and ends on 01/31.
user
Okay.  Give me one moment to see if we have any flights available.
assistant
Ok, take your time.
user
I'm sorry sir, but it seems that there are no flights that match your request.  Is there anything else I can help you with today?
assistant
It's ok, thank you for searching for the flight.
user
Your welcome.  Have a nice day.
