Hope this isn't off-topic, but related to getting from the 3 main airports into Manhattan via rail:
--LGA - nope (well, you need to take a bus or something else first, to get to a subway station) - looks like 2022 (maybe...) will bring a LGA AirTrain link, unfortunately takes you the wrong direction (Met stadium vs. one of the stations closer into the city), but nothing unworkable because you are already so close.
--JFK - AirTrain ride takes you to various stations, but you still have a fairly long ride due to it all being 'local' subway vs. an express train (there might be express subways, I don't know).
--EWR - maybe the best today? Quick AirTrain ride, then you get on another train that takes you right to Penn.

While I don't think it would ever happen (politically, NIMBY, financially), having a direct train connection from the airports right to a larger Manhattan station would be great. Imagine a loop from JFK, thru Brooklyn, up the center of Manhattan, to LGA, thru Queens, back to JFK. Maybe 6-8 total stops, just at the airports and major stations. Part of the concept like express lanes on a freeway would be to mitigate some of the crushing commute traffic so you could arrive at the airports during AM/PM commute times and be able to get on the trains.
