Hi.
Hello, how may I help you?
I am Barbara Scott. I want to book a ticket from IAD to PHL, can you help me?
Sure, may I know your dates of journey please?
My travel dates are 10/30 and 11/01.
Ok, please wait for a mean while.
Sure.
Sorry Scott, there is no flight found under your travelling details.
No problem, thanks for checking.
You are welcome.
