Hello, myself Patrick King.
Hello, how can I help you today?
I am planning to book a flight ticket from AUS to IAD, can you please do it for me?
May I know your travelling dates?
Sure, I would like to fly on 11/11 and 11/13.
Sorry, no flights are available for you.
That's ok, thank you for the information.
