Hi.
Hello.
I am Helen Green.
How may I assist you today?
Can you find a direct flight for me from LAS to DCA, to meet my school teacher.
May I know your travel dates to search flight for you?
Sure, my trip dates are 02/05 and 02/07.
Sorry, I could not find any flight with your details.
It's ok, thanks for your information.
It's my pleasure.
