Hello. Myself Kevin Baker.
Hello, how may I help you?
Can you help me to book a flight ticket from DCA to New York, JFK?
Sure, could you please provide your travelling dates to search for the flight?
Ok, please book for the dates Dec 21 and Dec 2. My return date is Dec 23.
Sorry to say, no flight is available for you.
That is ok, thank you for assisting me.
Welcome.
