Hello.
Hello, how may I assist you now?
Can you please help me in booking the flight ticket from DEN to EWR?
Ok, may I know your planned dates for this trip?
My travel dates are Mar 13 and Mar 15.
Do you need a direct flight?
 I am willing to travel in a single connecting flight.
May I know your good name?
Michael White.
I am very apologetic to tell you this information but there are no flights currently available for your trip.
Not an issue, thank you for the information.
Thank you for consulting with our services. Have a nice day.
