Hello. I am Richard King.
Hello Richard, how can I aid you today?
I want to meet my sister, who stays in BOS. Can you help me in booking a ticket from ORD?
Sure, I can help you with that. Could you please let me know your trip dates?
My planning dates are from 09/11 to 09/13.
Sorry Richard, there is no flight available on your provided dates which is travelling to your destination. Do you have any other preferable dates to travel?
It's fine, anyway thank you for your help. No thanks.
Ok, have a nice day.
