Hello.
Hello, how may I help you at this moment?
I am Donna Moore. I would like to celebrate my birthday at Chicago, can you please help me to book a flight from DEN to ORD?
Sure, I will help you. Please send your travelling dates.
Sure, my travelling dates are 10 Oct and 12 Oct.
Do you have any requirements to be met? Sorry Donna Moore, there is no flight available on your travelling dates.
That's ok, thank you for your information.
You are welcome, have a nice day.
