Hello, myself Robert Jackson.
Hello. How can I assist you today?
I am planning to book a flight ticket to IAD from LAS, can you please help me out?
I am ready to help you with that booking, may I know your preferable dates?
Sure, my planned travelling dates are 05/17 and 05/19.
Just give a moment.
Ok, take your time.
Sorry Rober, no flights are available on your desired route.
It's ok, thank you for the information.
Thank you for reaching us.
