Hi.
Hello.
I am Robert Wright.
What help that I can assist you?
Can you help me in booking from DCA to DTW, as there is a volley ball match?
Sure, I can help you and can you please mention your preferable travel dates?
My trip dates are Jun 16 to Jun 18.
Do you have any specific depart and arrival time for this trip?
I need a connecting flight which return in evening.
Would you like to travel in a business class or in an economy class?
I am ok with any class.
 There is a flight which will return at 2:00 AM and the flight number is 1011 in Delta airlines, can I confirm your flight ticket booking?
You can reserve it.
I have confirmed your flight ticket booking on your journey dates.
Thank you.
You are most welcome and have a happy journey.
