New York City has three international airports: Newark (EWR), John F Kennedy (JFK), and La Guardia (LGA). All three will get you within a taxi drive to the venue. JFK and EWR have relatively easy public transit via train/subway systems, LGA has bus service that connects to Manhattan.
If not using public transit, we recommend using official taxi dispatch lines or Lyft/Uber, avoid solicitations by drivers on the curbside.
