Hello, I am Charles Davis.
Hello, how may I aid you today?
I would like to go to a event in Houston, so could you please book a ticket for me?
Sure Davis, I am here to help you out. Please provide me your location airport codes.
Sure, my source and destination airport codes are OAK and IAH.
Please mention me your trip dates to check the best flight in your route.
I would like to go on 04/16 and return back on 04/18.
Sorry Davis, there is no flight with your desired travel dates.
That's ok, thank you for checking.
Thank you for reaching us.
