Hello, Jonathan Walker here.
Hello, how may I help you?
I would like to travel from IAD to IAH. Can you please help me to book a ticket?
Sure, could you please provide your travelling dates to search for the flight?
I want to start on Nov 24. I intend to return on Nov 26.
May I know your class preference?
I am comfortable with any class.
Sorry to say, no flight is available for you as per your requests.
Ok, not an issue.
