Hi.
Hello. How can I help you?
I am Michael Roberts.
How are you Michael Roberts?
I am planning to travelling  with mother from DCA to OAK, will you help in booking a flight ticket? My date of journey is on 03/25 to 03/27.
Sure Michael, can I know your travel dates please? Please wait a moment. Sorry Michael Roberts, there are no flights as per your request.
That's ok.
Thank you for approaching us, have a good day.
Thank you for your help.
You are welcome.
