Hi.
Hello. How may I help you?
I am Linda Adams. Can you help me to book a flight from DCA to EWR?
Sure, I am obliged to help you in that plane ticket booking. Can you please share your moving dates for better searching of flight?
My travelling dates are 06/03 and 06/05.
  Is there any another specifications on your trip, so that I can arrange like that only.
I need a connecting flight from DCA.
Sorry to say, there is no flight found on your route to book your ticket.
No issues, thank you for your time.
Welcome, have a good day.
