Hi. I am Jerry Baker.
Hello, how may I provide service to you?
Can you help me in booking from LGA to ATL, as there is a business meeting to attend?
Sure, may I know your journey dates please that you prefer to travel?
My trip dates are Dec 28 to Dec 30.
Do you prefer business or economic class in your journey?
I am ok with any class, but my depart time should be in the evening and return time is Afternoon.
Do you have any restrictions on connection limit?
I need a connecting flight.
We found a American Airlines  with 1019 flight number matching your preferences, class is economy, price is 200.
Ok.
And your departure at evening and return flight at afternoon. Shall I proceed?
You can book it.
Your ticket has been reserved.
Thank you.
Thank you for choosing us.
