Newark Liberty International Airport: For West New York itself, a taxi/rideshare is usually the sane choice: roughly 25–50 minutes and about $50–80 including the usual airport/traffic variables. The budget route is AirTrain plus NJ Transit to New York Penn Station, then a 15-minute walk to Port Authority Bus Terminal for a 127, 128 or selected 159 bus toward West New York; allow 75–105 minutes and roughly $20–25 total. There is no useful direct rail link to town.
John F. Kennedy International Airport: Do not take an expensive door-to-door shuttle. Take the AirTrain to Jamaica, then the LIRR to New York Penn Station; from there either take a taxi/rideshare across to West New York or walk to Port Authority Bus Terminal for NJ Transit buses 127/128 (some 159 trips also serve the area). Allow 90–120 minutes by transit and about $15–25 before the final bus; a car from Penn is usually another $30–55 and saves a cumbersome last transfer. A direct JFK car ride can be much slower in traffic and is commonly expensive.
LaGuardia Airport: With light luggage, use the free Q70 LaGuardia Link bus to Jackson Heights–Roosevelt Avenue, take the E train to 42 St–Port Authority Bus Terminal, then board NJ Transit 127 or 128 for West New York. It is about 80–105 minutes and roughly $7–10 total. A taxi/rideshare can be faster but is traffic-dependent—typically 35–75 minutes and often $55–90 once congestion and tolls are factored in.
New York Penn Station: This is the most useful intercity-rail arrival point. Walk northwest to Port Authority Bus Terminal (about 15 minutes), then use NJ Transit 127, 128, or the appropriate 159 service for your West New York address; buses run through the Lincoln Tunnel and take roughly 15–35 minutes after leaving the terminal. Budget about $3–5 for the bus. With luggage or a late arrival, take a taxi/rideshare instead; it is usually 20–45 minutes, not reliably quicker in rush hour.
Newark Penn Station: If your train stops here, do not assume it is a convenient transit hub for West New York. A taxi/rideshare is the practical transfer: about 25–45 minutes and roughly $40–65. Public transport generally means going into Manhattan or making multiple bus/PATH connections, so it is only worth it when money matters more than time.
