From the FAQ this category is only going to be available for Brazilian residents.

It seems a measure to offer more benefits for passenger traveling within Brazil with Priority Boarding, a couple of miles more and discounts on paid seats. I think this is to have a better value proposition against Azul and Gol for passengers that fly a lot but not so much

As long as there isn’t a lot of competition, I don’t think we will see this in other markets. Maybe Colombia in a couple of years?
