Hello.
Hello, how may I guide you?
I am Jack Green. I would like to book a flight ticket from ORD to BOS.
Sure, can I know your preferable dates?
Sure, I am planning to start on 10/29 and return back on 10/31.
I am sorry, there are no flights available.
Ok, no problem. Thank you for the information.
Thank you, have a good day.
