The fares from Newark ($6.65) and New York ($11.15) include a surcharge to cover the Port Authority of New York and New Jersey's debt and operating cost ($1.50 from Newark and $2.50 from New York).
Interestingly, there is the Airlink bus that runs from Newark Penn Station to Newark International Airport that cost $4.00. The regular 62 bus cost only a dollar. The Differences: the regular bus makes a few local stops before arriving at the airport. Both start and finish at almost the same spot: one bus lane apart.
Newark Penn Station serves as a major transportation hub. Besides being on the Northeast Corridor with Amtrak, NJTransit and PATH (To Manhattan) train service, it has NJTransit and Greyhound bus service.
