Hello,.
Hello, how may I help you?
I want to book a flight ticket on 08/15 to 08/17.
Ok, may I know your name?
I am Debra White.
Ok  Debra, can I know your travelling airport codes please?
I am planning to meet my childhood friend's in TX - AUS and my origin from TX - IAH.
That's good but sorry for inconvenience, all the flights are busy on those dates. So, there is no flight available for you.
It's ok, not an issue, thank you, for your good service.
Most welcome.
