Hello. My name is Kathleen Allen.
Hello. How may I assist you?
I just want to visit my sister's house, could you help me in booking a ticket?
Sure, I am happy to help you? May I know your travelling dates?
The dates are 09/15 to 09/17.
May I know your airport codes?
They are HOU to IAD.
Sorry to say that there is no flight found.
That's ok.
Thank you for contacting us.
