Hi, I am John Green.
Hello, how may I help you?
I want to book a flight ticket to Houston on 02/09 and will be returning on 02/11, can you help me to book a ticket?
Please provide me your airport codes.
I prefer to fly from AUS to IAH.
May I know your connection limit?
I need a connection in between.
Sorry, there is no flight available according to your criterion.
Ok, thank you.
