<p>If you know someone going the same place as you, though, taxi can be convenient and fastest. $45 from JFK to anywhere in Manhattan (plus tip). So if you split that you would pay $25. Supershuttle is also a good option, $20 plus tip. But it takes more times, sometimes. Subway is the best, if you have minimal luggage. I usually take the shuttle, cuz I have two bags with me, usually.</p>
