Hi, I am Anthony Robinson.
Hello, how can I provide our service to you?
I planned to attend a press conference about a New product in New York  on 12/07. Could you please help me in booking a ticket from DCA?
Ok, I can help you in booking. Please let me know when would you like to return?
I intend to return on 12/29 from New York.
Is there any fare limit you need?
Yes, price should be below 200.
Ok, can you mention your destination airport code?
My destination code is EWR.
Ok, let me check what flights are available for you.
Sure.
Thanks for waiting. Due to some technical up-gradation at your destination airport we are unable to provide a flight for you.
No problem, I may go by road ways. Thank you for your information.
Thank you for opting us.
