AFAIK the slots are by hour, not aircraft type. AA could probably operate as many flights as it wants at 6 AM. It's the peak hours (which at JFK are in the afternoon) where slots are tight.
Regarding the sizing of planes, keep in mind that for inside the perimeter, demand is split between LGA and JFK, which can limit the size of plane that a flight to JFK can support. This is true for both O/D and connecting as there are plenty of people connecting at LGA.
My guess is that you'll see more adds along the lines of the recently announced JFK-SAT, where SAT is outside the perimeter, is a large area to have good O/D, and has a reasonable FF base for AA. I know it's boring for folks on FT but someone is running the numbers at AA.
