Hello.
Hello, how may I aid you today?
Can you please help me with booking a flight ticket from LAX to JFK?
Sure, can I know your good name please?
I am Michael Thompson here.
 When you are willing to travel?
My travelling dates are from Dec 14-16.
Do you need direct flight or connecting flight?
I would be comfortable with single stop over.
 Would you let us know if you have any other preferences?
I prefer business class and my depart has to be in evening.
Sorry to say that, there are no flights available on the routes of your journey.
No problem, thank you for the information.
Thank you for availing us.
