Hi, I am Jonathan Green.
Hello, how can I help you today?
As I am a journalist, I want to visit Library of congress to get some information from the books. So, can you please book a flight ticket from Oakland, OAK?
Sure, may I know your other airport code?
My landing point is Washington, DCA.
Let me know your planned dates.
Sure, I intend to start on 09/03. After completing the trip, I will return on 09/05.
Please wait for a while.
Ok.
Thanks for waiting, there is no flights found on your given requirements.
It's ok, no problem. Thank you for your kind information.
Thank you.
