Hell.
Hello, how may I help you?
My name is Frank Martin. I would like to travel from AUS to IAH.
Ok, please help me with your travel dates.
My preferable dates are  08/11 to 08/13.
I found a flight 1008 of Southwest airlines matches with your preferences, can I proceed?
Please proceed with the booking.
Your ticket has been booked.
Thank you.
Most welcome.
