Hello.
Hello, how may I aid you?
Robert Lopez here. I have a program to attend, so could you help me to book a  ticket from IAH to ORD.
May I know your trip dates?
My travel dates are 08/14 and 08/16.
Do you prefer any connections?
I would prefer connecting flight with business class.
May I know your specifications?
There are none, thank you for asking.
Sorry, no flights found on your route.
No problem, I will make an alternate arrangement.
Thank you.
