How long does the AirTrain + LIRR take?
The AirTrain takes about 10 minutes to get to Jamaica Station. It takes about 5 minutes to switch from the AirTrain to the LIRR, and the LIRR takes about 20 minutes to get from Jamaica to NY Penn Station. If your flight arrives at Terminals 1, 2 or 3 at JFK, you can cut a few minutes off of your AirTrain ride by taking the “internal” AirTrain to the Terminal 8/9 stop and switching there to the “external” AirTrain to Jamaica. This way you avoid having to go all the way around to all of the terminals. Going to JFK Termainls 8/9 you can do the same trick: get off the “external” AirTrain at Terminal 1 and switch to the “internal” AirTrain to 8/9.
