JFK has more than 30 airport lounges where you can step out of the commotion of the terminal and into a quiet sanctuary. Some are quite reasonable considering the complimentary food, beverages (including beer, wine and liquor) that are usually included. Check out LoungeBuddy for JFK choices and booking just a one-day pass (as opposed to signing up for an airline credit card or membership), even on the day of your flight.
