Hi. I am Donald Williams.
Hello. How can I assist you?
 I want to go for an industrial tour conducting by our college management, can you please book me a ticket from DEN to ATL?
Sure, may I know your journey dates please?
My travelling dates are 12/26 to 12/28.
Delta airlines is having a flight with travel charge of 200, shall I proceed booking?
You can book it.
Your ticket has been booked with flight-1022, have a safe journey.
Thank you for helping.
It's ok, thank you for choosing us.
