I want to travel from MCO to SGN anytime Mid-January and returning anytime Mid/Late February (Flexible on Dates). Airline doesn’t matter too much but I’d like to experience business class flying using my Amex/Chase/Citi points.

Researching I’m seeing business tickets around 600k points which is wayyy higher than what I have. As I’m a newbie how can I be able to make my dream happen?
