Hi, I am William Walker.
Hello. How can I aid you?
I would like to travel LAS to attend client meeting, can you assist me to book a flight ticket from PHL?
Sure, help me with the travelling dates.
My travelling dates are on 03/23 and return back on 03/25.
Sorry, there is no flight on your requested dates.
Ok, no problem with that one.
Thank you for choosing us.
