PS JFK Loads

With the move of PS to EWR from JFK coming in October I found that this will most likely be my only time to try non reving from JFK on United. I am trying to leave on Aug 3/4 and wanted to know if anyone has ever gotten first on PS. The seats are all about 10-15 in F and 10-15 in Y. I also wanted to know the reason for the lack of upgrades on these routes when its aimed for Business fliers.

No complimentary upgrades on the PS routes, so the upgrade list is narrowed down to those with the certificates and such. I'm sure a nonrev has gotten F before, but you know... be happy to get a seat!
