Hello, how can I help you today?
I am a scientist and I have to do research on plants at SFO location, can you please book a flight ticket for me from DCA locations?

Thank you and my planned travel dates are May 2nd and I will return back on May 4th.
May I know your connection limit?
I will prefer to travel in single connected flight.
Do you have any other specifications?
I would like to return back in evening time.
