Hello. This is Mr. Kenneth Thompson.

Hi Kenneth, how can I help you?
assistant
I need to book a flight from New York-EWR to Vegas-LAS.
user
What days would you like to depart and return?
assistant
I need to leave New York on October 7 and meet with a client until October 9.
user
Please wait while I search for flights based on your criteria. I found a flight on Frontier Airlines for 300, shall I book a ticket?
assistant
Is there anything for cheaper.  Say, 200?
user
I'll adjust the search parameters. Just one second. I was unable to find any flights fitting your criteria. Is there anything else I can do for you? Thank you for choosing us, have a good day.
assistant
Bye.
