NEW YORK - (AP) - The Port Authority of New York and New Jersey is considering taking over operation of Atlantic City International Airport to help reduce air traffic congestion at New York-area airports.

The agency announced Thursday that it has authorized $3 million for a study.

The Port Authority operates the New York area's three major airports - Newark, JFK and LaGuardia - in addition to Teterboro Airport in northern New Jersey and Stewart Airport in Newburgh, N.Y.

New York's three major airports annually handle more than 100 million passengers. Delays at any of the three often have a ripple effect on air travel throughout the United States.

Atlantic City's airport is operated by the South Jersey Transportation Authority. A spokesman for the authority didn't comment on the Port Authority's plans.
