The answer is correct
It's called AirTrain and it's free between the JFK terminals. In the terminals you cross the street and generally go up 1 floor and take it to one side or the other depending on how close you are to the circuit's exit. Look at the map. If you want to leave the airport you have to go to the two stations for this purpose: Jamaica or Howard Beach. Even these terminals are free but to get out of them you must pay $ 7.75 with the metrocard that is bought right there usually in the self-consultations. If you don't have the metrocard, add 1 dollar for it. Now the metrocard is used to buy an unlimited subscription that lasts a certain time (7 or 30 days) and / or to charge you a balance. Example: You want to get to Midtown Manhattan. You go to Jamaica station. Metrocard + 7.75 to leave the station + 2.75 for the subway ride (subway E). TOTAL 11.50. If you decide to buy a pass that lasts 7 days you get 33 dollars. This allows you to travel on all local buses and subways.
I dont know. I've never used it. But I will investigate.
