Hello.
Hello. How can I help you today?
My name is Cynthia Clark. I have a plan to meet my friend in Washington, can you help me for booking a flight ticket?
Sure, can you please share your airport codes?
My travelling airport codes are from  DCA to ORD.
Please share your trip dates too.
My travelling dates are from 10/23 till 10/25.
Sorry, no flights are available on your route.
That's ok, thank you for checking.
Welcome, have a nice day.
