GOL on ID Travel

I'm trying to get into PUJ on Oct 1st and most flights are filling quickly. However, GOL, if I'm understanding their numbers right, is wide open out of MIA and MCO. It has a green smiley and where it usually displays the fair bucket numbers, it only has one fair bucket of Z and it says Z81. The numbers change for various days so does that mean GOL only has a single bucket and is selling 81 more seats? Flights less than a week out are $105 + tax so I figured it has a bunch of seats at the least with prices so low. Can anyone confirm that I'm looking at it the right way?

edit: I took a quick look in dlterm and they do have multiple buckets and it's 9s across the board so I suppose that's good.
