Hi, I am Justin Perez.
Hello, how can I assist you today?
I need to travel to Houston HOU to enjoy river rafting with friends. Can  you make a reservation from IAD?
 Sure, I would be happy to help you. Do you prefer any halt in between your journey?
I need a direct flight.
May I know when you have planned to travel?
Sure, my planned dates are 01/09 and 01/11.
Ok, please wait a moment, let me search a flight for you.
Sure.
 Thanks for your precious time. We found Southwest airline fare of 400. Shall I proceed for booking with a direct flight?
Do not proceed. I am looking a flight within fare 200.
Ok, thank you for reaching us.
