Hello, I'm Michelle Walker.
Hello Walker, how can I help you today?
I'm having convocation event at Oakland university, can you book my ticket from MCO to OAK?
What are your planned dates for this journey?
My preferable journey dates are from 04/20 to 04/22.
There  is no flight available for you in your  route.
It's ok, not an issue.
Thank you, have a nice day.
