Hi, myself Amanda Walker.
Hello Walker, how can I assist you today?
I want to visit my uncle's place at Oakland, can you please help me to book my flight ticket from DFW to OAK?
Could you please let me know your trip dates?
I will depart on 07/09 and return back on 07/11.
Please wait for a while.
Sure.
Sorry Walker, there is no flight  available for you.
Not an issue, anyway thank you for checking.
Thank you for approaching us.
