Hello. I'm Edward Evans.
Hello, how may I help you for today?
I am planning for a round trip from DCA to DCA, can you please help me with booking a flight ticket?
Sure, could you please provide your travelling dates to search for the flight?
Sure, I would like to take off on 09/02 and return back on 09/04.
Please hold on for a moment.
Ok, but please make sure that the price limit does not exceed 500.
