Hello, myself Melissa Martinez.
Hello Melissa, how can I aid you today?
I would like to meet my brother on his birthday, could you please help me to book my flight ticket from LAS to OAK?
Sure, I will help you. Please mention your travel dates.
Sure, I will depart on 07/05 and return back on 07/07.
Ok, please wait for a moment.
Sure.
Sorry Martinez, there is no flight available for you as per your requirements.
Sad to hear that, thank you for checking.
You are welcome.
