Hi. I am Joseph Green.
Hello, how can I help you?
I am planning to conduct a cultural event in my college at Washington, IAD. Reserve me a flight ticket on 12/06.
Sure, May I know when will you return your journey?
12/08 is my arrival date.
Help me with your source airport code.
My take off airport code is Houston, IAH.
Please, wait for a moment.
Sure.
Thank you for waiting.
Ok.
