Hello.
Hello, how can I aid you?

That's good to hear. Then what are your planning dates?

Ok, may I know your returning details?
My return date from Washington-IAD airport is on 10/23.
May I know your respected name please?
My name is Edward Parker.
Ok Edward, sorry to tell you that there are no flights available on your preferred dates. Do you like to prefer any other date to fly?
