Hi.
Hello, how can I help you?
I am Jacob Walker. Can you help me searching  flights from CLT to HOU to attend my project seminar?
Sure, may I know on what dates you have planned to travel?
My travelling dates are 04/24 and 04/26.
Sorry for the inconvenience, there is no flight available on your requested dates.
Oh! It's ok, no problem.
You are welcome.
