Hello. Myself Jonathan Walker.
Hello, how may I help you?
I need to travel New York, can you please book flight ticket from OAK and LGA?
Sure, may I know your travelling dates?
My journey dates are 11/24 and 11/26.
Sorry to inform you, there is no flight available as per your request.
That's not an issue, I will choose any other source to reach my destination.
Most welcome.
