Hi. I am Emma Evans.
Hello, how may I guide you?
I would like to book a flight ticket from HOU to CLT.
Sure, can I know your preferable dates?
I am planning to start my trip on 07/12 and return back on 07/14.
I found a flight 1012 of Delta  airlines matches with your preferences, can I proceed?
Yes please proceed.
Your ticket is booked.
Thank you.
Thank you, have a good day.
