Hello, how may I guide you?
assistant
I want to meet my wife who lives in Boston on this weekend. So, can you please check for the flights from DCA to BOS?
user
Ok, can I know your preferable dates?
assistant
My journey will start on Oct 19th and I will be returning on Oct 21st. I only need an economy class reservation.
user
I am sorry, there are no flights available.
assistant
Oh! That's fine. Thank you for checking anyways.
user
Thank you, have a good day.
assistant
Most welcome.
