Hello.
Hello, do you need any help from us?
I am Debra Turner. Can you please book a business class ticket from OAK to AUS?
Sure, could you please share your departure and arrival day?
My travelling dates are 10/21 and 10/23.
Ok, do you have any other specifications?
      I want to depart in the evening and return at evening.
Sorry, there is no flight on your requested travelling dates.
That's ok, thank you for the response.
You are welcome, have a great day.
