Hello.
Hello, how can I provide assistance to you?
Can you please help me to book a flight from DTW to DCA?

Do you need direct flight or connecting flight?
I need a connecting flight.
If you can help me with your name, I can check with the availability of flights.
Myself Gary King.
 Would you let us know if you have any other preferences?
