Hi.
Hello.
I am Sandra Anderson.
How may I help you today?
Can you help me in booking from IAD to DTW?
Ok, may I know your travelling dates?
My journey dates are 11/10 to 11/12.
Sandra Anderson, please wait for a moment. Sorry to inform you, there are no flights available as per your request.
That's ok, thank you for checking.
Sorry for the inconvenience. Have a great day ahead.
