Hi.
Hello.
Jacob Robinson here.
How can I assist you?
 I am planning to travel from OAK to PHX to attend a convocation party, can you please help me with booking a flight ticket?
That's great. Can I know your journey dates?
My required dates are from 07/12 till 07/14.
Sorry Jacob, there is no flight available on your requested dates.
It's ok. Thank you for checking.
You are welcome.
