Compare that to anywhere in Australia where you can be sure security won't take more than 10 minutes - you can arrive at the airport with 45 minutes before your flight and still be waiting 20 minutes after you check in and pass security before you board.
I'm not too big of a fan of the AirTram + Long Island Railway (LIRR) route, which ends up at one of the major train stations, has on outside terminal (not great in the winter and slow with a lot of things to remember to do), but is about half price of that.
I've recently started doing Penn Station -> Jamaica w/ LIRR -> AirTrain, it's miles better than subway and almost preferable to car if you're paying for the car.
