Last August I told you that small dogs in carriers are allowed onboard AirTrain Newark, which takes you from Newark Airport to New York’s Penn Station or Trenton (via a connection with NJ Transit) for much less than the cost of a taxi.
Another inexpensive alternative for passengers arriving at Newark is the Newark Liberty Airport Express, a bus that leaves from Terminals A, B and C and takes you to three stops in the city: Port Authority Bus Terminal, Bryant Park (the corner of 42nd St. and 5th Ave.) and Grand Central Station. Buses to Newark Airport also depart from each of those stops.
One-way fare is $15; round-trip is $25. You’re encouraged to buy tickets on-line, but you can also buy them on the bus. The buses run every day of the year, and aim to “come to every stop every 15 minutes during the day.” The site says nothing about dogs, but a customer service rep told me in a phone conversation that small dogs in carriers are allowed onboard.
