Hi.
Hello, how may I serve you today?
Can you help me in booking a flight ticket from DCA to SFO?
Sure, please share me your trip dates.
I want to travel on 10/06, and return on 10/08.
If you can help me with your name, I can check with the availability of flights.
I am Nicole Lewis.
 Would you let us know if you have any other preferences?
I prefer for normal cost airline.
Sorry to say that, there are no flights available on the routes of your journey.
Ok, no issues. Thanks for the information.
