Hello, I am Mary Rodriguez.
Hello, how may I aid you?
I am excited to visit the Redwood Regional Park in Oakland, CA - OAK from CA  - LAX. Can you book me a ticket with price limit of 500?
Ok, may I know when you want to travel?
I start on 07/12 and return on 07/14. Make sure there should be one connection.
Ok, please give me a moment. I will check the availability of flights and revert you.
Sure.
Thanks for being patient. Unfortunately there are no flights available at this moment according to your request.
OK, no issue. Thanks for the information.
Thank you for reaching us.
