Hello.
Hello.
Brian Wilson here.
Brian Wilson, how can I aid you today?
Can you please help me in booking a flight ticket from SFO to JFK?
Sure, I am here to help you. May I know your travel dates please?
Sure, my travel dates are from May 18 to May 20.
Ok, hold on for a moment. Let me check the best flight for you. I found a flight for you with Delta airline and it costs you 200. Shall I proceed?
Please make sure that my return time must  be in the evening.
Sorry Brian Wilson, there are no flights available on evening time in those routes. Sorry for the inconvenience provided.
That's ok, no problem. Thank you for the information.
Welcome, thank you for choosing us. Have a great day.
