Whichever airport you arrive into in New York, there are plenty of transport links to take you to your destination. Here are some of the options...
JFK Airport is in Queens, just 15 miles from central Manhattan. It is well served by transport links to hotels and central attractions. Options include hopping into a yellow taxi, taking the AirTrain and travelling by bus - both public and private bus companies run services from New York's airport.
Newark Liberty International Airport is in New Jersey, 14 miles from central Manhattan. Again, transport options include yellow cabs, the AirTrain and public or private bus services.
For both airports, if you are travelling in a group, a taxi is probably the best option as you can split the cost of the trip and, if you are tired after a long flight, the thought of lugging bags on and off public transport won't appeal.
Alternatively, if you plan to explore the areas outside New York City, car hire could be a good option. Pre-book your car hire in advance, pick it up at the airport and set off on your adventure.
