Robert Boyle, executive director of the Port Authority of New York & New Jersey, announced his resignation from his post at a meeting on Wednesday evening.
It was reported that Boyle told the agency's 7,000 employees that he had decided to leave his post as soon as a transition could be accomplished.
Boyle was appointed to the head position of the bistate agency in March 1997. The organization runs the three major New York airports - John F. Kennedy, Newark and LaGuardia. JFK and Newark have extensive cargo operations.
While a Port Authority spokesman did not elaborate on whom Boyle's successor would be, industry sources said a possible choice is Lillian Borrone, who was promoted to the number two job of assistant executive director on September 11 this year.
