It might cost to pick up or drop off passengers at Newark, Kennedy and LaGuardia airports.

The Port Authority of New York and New Jersey is exploring airport access fees as a way to deal with growing curbside congestion outside airport terminals.

The agency says in an email that it is examining the fees in the wake of recent changes in passenger preferences that have altered vehicular traffic in front of terminals. The agency says there are more vehicles-for-hire using the front of the terminals as staging areas.

The Port Authority has not charged to drop off or pick up. But other airports around the country do and car services usually pass the cost on to riders.
