I am a Black elite status.
LA714 SCL GRU had 8 J seats when coupons applications open (it's the daily widebody flight). I started as 3, then got down to 8 because BS applied later on.

Now only 1 seat available and still on 8th position.

I guess they sold on the auction

Same happened to me on the GRU SCL.
Black status has been useless this year so far. Let's see in a couple of days for a GRU JFK flight
