Hello.
Hello. How can I help you?
I am happy that there is a special airline for me from CLT to IAH. Can you book me a flight ticket in that airline?
That's good, I will help you with that. May I know your name please?
My name is Charles Clark.
Can you please mention the travelling dates?
Preferably, from 11/30 to 12/02.
Ok, please wait for a moment. Sorry, there are no flights found on your requirement. Do you have any other plans to travel?
 I haven't expected this, I will think what to do further. That's all for now. I need some time to plan. I will reach you soon.
Ok. Thank you for approaching us, have a nice day.
