Hi.
Hello.
My name is Donald White.
Do you want me to help you with anything?
 I am planning to visit Denver zoo, could you book a ticket from ORD to DEN?
Sure, may I know your preferable dates please?
The travel dates are from 01/14 to 01/16.
Ok, please give me a minute so that I can check the availability of flights for you.
Ok fine.
I am sorry to infirm that there is no flight found.
That's ok, thank you for your information.
