As mentioned you can see movements but it would be near impossible to get some shots from the monorail. Try to meet up with an JFK
local so they can guide you around. I know Art Brett amongst others always go to JFK
. Don't do what I did, I could not meet up with anyone at the time, so me and two friends went to JFK
eventually got to Howard Beach ($20 cab fee for a 5 minute walk) and saw that the wind was the wrong way. We got screwed.
