Flying from Newark Liberty

Three terminals A, B and C connect via the AirTrain people mover to the NJ Transit and Amtrak rail station, with NJ Transit reaching New York Penn Station in 25 minutes for around $16. Newark fares are typically a few dollars cheaper than JFK on the same routes thanks to United's heavy capacity; international long-haul is the deepest of the three NYC airports for European destinations.

Morning summer fog (May–August) routinely causes ground delays; book afternoon departures or mid-day arrivals during that window.
