As of 2015, the Westchester County Airport (HPN) serves an average of 1.5 million airline passengers per year.

On an average day, approximately 39 flights operated by eight airlines depart from the main terminal.

Flights offer direct service to and from business and recreation destinations throughout the United States. Through connections are also available to major cities around the U.S and the world.

Westchester is unusual, in that since the early 1980s, the County has strictly regulated the flow of commercial aircraft and passengers in respect to the impact of aircraft activities to its surrounding communities. Westchester County and the airlines serving the airport operate under a Terminal Capacity Agreement that limits terminal use to 240 scheduled passengers per half hour and four available gate positions. This limit, however, is increased during peak holiday travel periods.
