Hello. I am Gregory Phillips.
Hello, how may I guide you?
I want to book a ticket from DFW to BOS to attend seminar, can you help me in booking?
Sure, can I know your preferable dates?
I am departing on 09/06 and return on 09/08.
I am sorry, there are no flights available.
That's ok, thank you for your information.
Thank you, have a good day.
