Hi.
Hello. How may I help you?
I am Katherine Taylor, can you help me to book a flight from IAD to SFO?
Ok, can I have your travelling dates to get a flight for you?
My travelling dates are 07/13 and 07/15.
Wait a moment please.
Sure, take your own time.
Sorry to inform you, there is no flight found on your route to book a ticket for you.
It's ok, thanks for your information.
Thanks for reaching us, have a good day.
