Hello. I am Scott Edward.
Hello, how can I help you?
I need to book a flight ticket to visit Metropolitan museum with my colleges in New York EWR. Can you please help me for booking from IAH?
Sure, may I know your travelling dates?
I want to visit on 04/24 so, I would like to start on 04/23 and I intend to return on 04/25.
Sure Scott, I will help you in booking a ticket on 04/23. Do you have any price limit because that makes me easy to flight under your range?
As I have enough money today, I can pay up to 1000.
Ok. Please wait for a couple of minute, I am searching for the best flight under your price limit.
Sure, I will wait.
Sorry Scott, I am sorry to inform that there  are no flights found on your requested  dates.
That's ok I can reach my destination in another way.
Thank you for approaching us Scott, have a nice day.
