How do I get to 811 7th av. Times Square from the airport

Just get the ticket from the airport. There is a ticket for Amtrak which is a very fast and convenient train from the airport to Time Square. It's the train 7 it will take you to Timesquare directly. Please always ask questions, there are NYPD officers at the airport, you can ask them question whenever you need to. They will be very supportive

There are a variety of public transportation from JFK to the Times Square area (42nd Street, Port Authority of NY). Inquire in JFK for their Airport Shuttles. It would also be the cheapest method of transportation. The Ariport Shuttles usually do not have any stops outside of the airport to the city. So time wise, it going to be the same time as the taxi that is pulling out in front of you.

Take a yellow cab. Cost you 65U$. Front door delivery and with some luck a nice driver.
