According to JetBlueBestFareFinder here are the unreserved seats:

 

To Orlando           13-10-10=33

To Fort Lauderdale     12-13-16=41

 

Based on 600 available seats this equates to a load of 87.66%    Again do not forget about 20% Dunkin Donut discount on JetBlue Tickets.  Read this post for details. 

Bottom line we are always seem to be in the mid-80’s, which seems pretty good to me considering July-August are the off peak months.
