Hi.
Hello, how may I help you today?
Sarah Lewis here. I am a journalist, I have to interview a celebrity at Dallas. Please book my ticket from DCA to DFW.
Sure, can you please share me with your dates of journey?
 I am planning the trip on 04/27 and after that I will catch the return flight on 04/29.
Please wait for a moment.
Ok.
Sorry Sarah, there is no flight found as per your travelling details.
It's ok, no problem. Thank you for your information.
You are welcome always.
