Hi.
Hello, how may I guide you?
I am Kimberly Robinson. I would like to book a flight ticket from OAK to DEN.
Sure, can I know your preferable dates?
I am planning to start on 04/09 and return back on 04/11.
I am sorry, there are no flights available.
Ok, no problem. Thank you for the information.
Thank you, have a good day.
