Hello, Thomas Parker here.
Hello, How may I help you?
 I want to go New York to visit my daughter's convocation day. Will you book a ticket to New York?
Sure, May I know journey details?
Fine, my origin airport is PA - PHL and destination code is NY - JFK. My depart day on 02/03 and return day on 02/05.
Please wait for a moment, I will check and get back to you.
OK.
Thanks for waiting, We did not find flight with your requirement.
Fine, no problem.
Thank you for visiting us, Have a great day.
