Hello, I am Joseph Allen.
Hello. How can I aid you?
I need to attend workshop in Smithsonian Institution at Washington, DCA. Can you help me with booking a connecting flight ticket?
Ok, help me with your travel dates?
My travelling dates are from 03/21 to 03/23.
May I know your journey points?
My source code is LAS.
Sorry, no connecting flights are working on your travel dates.
No problem, thank you for the information.
Thank you for availing us.
