Hello.
Hello, how can I help you today?
My name is Richard Hall. I want to book a ticket from Detroit-DTW  to visit my home town Chicago-ORD.
Sure, may I know your travel dates?
My departure date is on 12/07 and return from Chicago on 12/09.
Sorry Hall, I did not find any flight basing on your details.
That's ok, thanks for your help.
Thank you for reaching us.
