<p>hi there
I live on Long Island and use McArthur/Islip regularly…just came throught there Sat night.
Its a $5 shuttle ride to the Ronkonkoma Long Island Rail Road station and then a train into Manhattan to Penn Station…probably about $14 or so and yes an hour and a half.If you are staying anywhere NOT in the Penn Station/Times Sq area (where train goes to) you will need to use a subway or taxicab from there.
Trouble with the LIRR is its on a schedule,it doesnt run continously like the subways.Heres the LIRR link <a href=“http://www.lirr.org,it%5B/url%5D”>www.lirr.org,it</a> will have that branch of the LIRR’s schedule for you which you can estimate from your arrival time at the airport plus baggage time (not so bad there its a small airport) plus shuttle commuting time to the station.All in all you’re looking at adding many hours to your trip but its doable.
It just might work in your favor to take a taxi from the airport into Manhattan.It will be a flat rate and theres a taxi stand right outside of baggage claims,especially if you’re travelling with other people.</p>
