Hi, Paul Green here.
Hello, how may I assist you?
 I planned to celebrate my parents 31st wedding anniversary in LGA, can you help me to book a flight ticket from LAS?
That's great. Sure, on which dates you want to travel?
My planned dates are 01/14 to 01/16.
There is a flight-1002 of Delta airlines, do you fine with that?
Yes, book it to me.
Sure. Your ticket has been booked, have a nice journey.
